| Zeolite Y and its Derivatives (NaY, USY, ReY) | Zeolite Y is the main catalyst component used in FCC/RFCC refinery units. The selectivity and catalytic activity of these types of catalysts are due to zeolite Y. Although this zeolite has other applications such as dehumidification, its mainly used in the world as the main catalyst component of the FCC/RFCC residue fluid catalytic cracking process. | Zeolites are generally minerals that are mainly composed of aluminosilicates with a regular crystalline structure, and they are commercially used in various industries as surface adsorbents. Among natural zeolites, only 9 types such as clinoptiolite, natrolite and stilbite are found in nature, and a large number of them are synthesized artificially and through chemical reactions. The structure of zeolite Y has a three-dimensional pore system in which the pores of 3.7 angstroms connect larger cages (with a diameter of 13 angstroms) to one another, which are known as supercages in this zeolite. | In the process cycle, first this product is prepared using silicate and aluminate sources. Due to the semi-stable nature of zeolite Y, its manufacturing steps must be carefully controlled, otherwise the final product will be another material and will not be used. Usually, solutions containing sodium hydroxide (caustic soda) are used for the synthesis of zeolites. Sodium in soda as a positive ion neutralizes and balances the tetrahedral negative charge of aluminum. This zeolite is called soda Y or NaY. Common sources of silica and alumina are sodium silicate and sodium aluminate, respectively. Crystallization of zeolite Y usually takes place within 35 hours at 100°C. Production of a high quality zeolite requires precise control of temperature, time and pH of the crystallization solution. NaY zeolite is separated from the crystallization solution after filtration and washing with water. NaY zeolite is not hydrothermally stable due to its high sodium content. The size of the particles, the size and volume of the holes and the active surface area of the product are its important features. | Заявка на материалы |
| 3A and 4A Zeolites | Among the applications of these compounds are the removal of oil and gas sulfur compounds such as mercaptans and H2S (which is essential in the process of refining crude oil and gas) as well as air pollutants such as CO and CO2. Another important application of these zeolites is the use in washing powders as an agent for absorbing calcium ions from water. | First Chapter | Advanced Catalysts & Absorbents27Chemicals26 Zeolites (Zeolites) are a type of molecular sieves, which, due to the high polarity of the internal surfaces of their cavities, are among the most important selective surface (physical) absorbers of water, water-soluble salts, and impurities and pollutants in water streams. In this way, they can be useful in wastewater treatment. These compounds are a type of aluminosilicate, which have different types based on their molecular structure and crystal network, and they can be divided into two types of natural and synthetic zeolites. Among the most important synthetic zeolites, we can mention zeolites A, X, Y and ZSM-5. Zeolite A has three different types named 3A, 4A and 5A. The reason for naming three types of zeolite A is because of their pore sizes, which are 3Å, 4Å and 5Å, respectively. The pore size is the main factor in absorption speed, absorption power and also the type of material that can be absorbed. These three types of zeolite can be converted into each other through the process of ion exchange in an environment saturated with metal salt. | The production steps are: 1. The reaction of the aluminum source (sodium aluminate) with the silicate source (sodium silicate) in the presence of sodium hydroxide and forming a gel 2. Gel aging 3. Hydrothermal reaction under specific temperature (about 100 °C) and time (crystallization reactor) 4. Concentration of zeolite cake formed from aqueous solution using Belt Filter system 5. Washing and drying the product using the Spin Flash Dryer method at 260 °C | Заявка на материалы |
| Molecular Sieves Based on 3A, 4A, 5A and 13X Zeolites | Zeolite 3A: sodium-potassium aluminosilicate with a pore diameter of 3 angstroms, used in the deep drying (dehydration) of fuel gases from the cracking process, unsaturated hydrocarbons (ethylene, propylene, butadiene and acetylene), aromatic compounds (BTX), light alcohol solvents (ethanol and methanol) and food grade CO2 gas. Zeolite 4A: sodium aluminosilicate with a pore diameter of 4 angstroms, used in drying gases, natural gas, alkane solvents, gases such as argon, drying agent for pharmaceutical packaging and electronic components. Zeolite 5A: calcium-sodium aluminosilicate with a pore diameter of 5 angstroms, used for drying natural gas and absorbing CO2, CO and H2S, nitrogen, hydrogen and inert gases. Zeolite 13X: X-type sodium aluminosilicate with 9 angstrom pore diameter, used for absorption of water, mercaptans and CO2, typical industrial air drying, low recovery temperature and long service life. | First Chapter | Advanced Catalysts & Absorbents29Chemicals28 Zeolites are a type of molecular sieves, which, due to the high polarity of the internal surfaces of their cavities, are among the most important selective surface (physical) absorbers of water and sulfur compounds of oil and gas (such as mercaptans and H2S), which is essential in the crude oil and gas refining process. In addition, they absorb impurities and pollutants from water streams (essential in wastewater treatment) as well as air pollutants such as CO and CO2 well. These compounds are a type of aluminosilicate, which have different types based on their molecular structure and crystal network, and they can be divided into two types of natural and synthetic zeolites. Among the most important synthetic zeolites, we can mention zeolites A, X, Y and ZSM-5. The reason for naming three types of zeolite A, namely 3A, 4A, and 5A, is because of their pore sizes, which are Å3, Å4, and Å5, respectively. The size of the hole is the main factor in the speed of absorption, the strength of absorption and also the type of material that can be absorbed. These three types of zeolite can be converted into each other through the ion exchange process in an environment saturated with the corresponding metal salt. | Synthetic zeolites consist of three main bases: zeolite powder, binders and other additives needed to improve properties. In general, the production process of these products includes the process of preparing the raw materials, mixing the components (in the right proportion and based on the formulation according to the specific application) and proper shaping. Based on the need, this shaping can be spherical (bead) (through the pen granulator or bead former) or string (through the extruder). Next, in order to remove the physical water in the macropores, drying is done. Finally, in order to remove the chemical water present in the meso and micro pores and increase the thermal, mechanical and chemical stability, calcination and activation operations are performed. Various BET, XRD, XRF, ICP, Atomic Absorption and Particle Size, Strength (Crush) and Attrition analyzes have been conducted by the company. | Заявка на материалы |
| SRU Sulfur Recovery Catalysts, Oxygen Scavenger, Titanium Oxide | Oil and gas refining | Sulfur Recovery Unit or SRU is used in the famous Claus process in gas and crude oil refining companies to convert hydrogen sulfide (H2S) to sulfur (S). | There are different types of sulfur recycling catalysts, which can be divided into the following three categories: 1. Aluminum-based catalysts (ρ-Alumina and γ-Alumina) 2. Oxygen scavenger catalysts (treated with iron) 3. Titanium oxide catalysts: it has multiple applications. The main role of this catalyst is to decompose and convert CS2 and COS compounds in the Klaus process to H2S after the catalyst function and sulfur production. Basically, because the CS2 and COS compounds in the Klaus process cannot be converted into molten sulfur and enter the environment as pollutants, due to the new environmental standards, refineries and petrochemicals are not allowed to release these compounds. Therefore, in order to eliminate these compounds, there is a need for a catalyst that can convert these compounds into H2S through the reduction process, and the produced H2S returns to the beginning of the Claus cycle and turns into elemental sulfur in the corresponding catalyst bed. | Заявка на материалы |
| Gamma Alumina-Based - Gamma Alumina Catalyst with Catalyst Base Synthesis | Some of the industries that use it include: oil, gas, petrochemical and other industries, such as steam reforming catalysts in steel industries, catalysts that reduce car pollutants, endothermic catalysts used in metallurgical and component manufacturing industries, etc. | This catalyst is used in the benzene chlorination unit of petrochemical industries. In this unit, the benzene in the EDC feed is a harmful factor for the continuation of the process and environmental pollution. The feed containing benzene and chlorine gas enters the reactor with gamma alumina catalyst and this catalyst selectively chlorinates benzene with high conversion percentage. Chlorinated benzene can be easily separated from the original feed. Gamma alumina or activated alumina has important physical and chemical characteristics, some of which are: high specific surface area, high mechanical (abrasion) and chemical resistance against acids and amphoteric property, porosity with nanometer dimensions, etc. For this reason, it can be used as a catalyst, catalyst base or adsorbent in many processes and reactions. | In this company, all stages of catalyst manufacturing from the base to the refinement stages have been done and by optimizing the production method, hole size, spatial distribution of holes and uniformity in the shape of the pores, better chemical and thermal stability has been created with the lowest cost. The presence of different stages of synthesis, the number of different components with high purity, the method of calcination operation and special standards in the use of the product and finally the long research and development process have increased the quality of the product. | Заявка на материалы |
| High Purity Alumina Catalyst and Adsorbent Active Alumina | Activated alumina as a moisture absorbent with a contact surface of more than 200 square meters per gram. This material is used for drying air, dehydration of natural gases and liquefied gases. | Active alumina is a product of aluminum hydroxide processing and has a very high absorption power. This material absorbs liquids and gases and does not soften, disintegrate or change its shape when immersed in liquids. Activated alumina has many tiny pores that act like a tunnel, so that when air enters this tunnel, water molecules are trapped, and the water in the air (moisture) sticks to the alumina, and when it passes through this tunnel, it dries. Also, active alumina with specific surface area above 300 m2/g and high porosity can be used as a catalyst in sulfur recovery unit (SRU), dehydration of alcohols and isomerization of olefins. | To produce this material, a method called GRANULATION PAN is used. In this method, in the first step, a flash calcination system is used to produce active alumina powder. For this purpose, the primary powder with specific granularity enters a tunnel-shaped path through a rotating plate with a specific drop rate and is exposed to a temperature of 550 to 700 degrees Celsius for a very short time. In this way, while creating an incomplete break between hydride bonds, finally active alumina powder is produced. | Заявка на материалы |
| Titania Catalyst | Refinement of gas and crude oil. | This catalyst is produced from titania compounds plus necessary additives during the process of material preparation, shaping and baking. It is used as one of the catalysts of sulfur recycling units for the hydrolysis of sulfur-containing organic compounds in order to increase the conversion rate of the unit. Another important feature of these catalysts is that they allow the reaction to take place at a lower temperature. The amount of titania used in these catalysts is usually more than 85%. | First, the initial titania powder with a special surface and suitable porous volume is added to the rotating cylinder to make it uniform and produce a suitable paste. Then, the appropriate pore-forming additive is dissolved in a certain percentage of water and added uniformly to the main powder. The blades of the powder machine mix the water solution and the additive well over a certain period of time, and a uniform and homogeneous paste is finally obtained. It should be noted that the additive used in this step should be selected in such a way that firstly it creates the required porosity and secondly, its remaining impurity does not harm the final product. In the following, the extrusion process is used to obtain filament-shaped catalysts. The production strands are then transferred to the drying chambers with the aim of removing water and surface humidification and thus facilitating the calcination process, and finally the dried product is transferred to the wagon shuttle furnaces for calcination.

| Catalysts for Mercaptan Removal by the MEROX Method (Par-MO-Cat) | The mercaptan removal catalyst is used in the MEROX process (MEROX =MERCAPTAN OXIDATION) in oil and gas refineries in order to convert methyl and ethyl light mercaptan sulfur compounds into disulfide in liquid gas and kerosene compounds | The primary washing of oil cutting is done using 2% soda. The extraction of light mercaptan (methylethyl) is done using a 30% soda solution along with a catalyst soluble in soda in the extraction tower. From the catalytic oxidation of heavy mercaptans in the vicinity of liquid catalyst and oxygen, sulfide dioxide is created. | The catalyst used in these processes are metal-organic compounds called metal-phthalocyanines. Cobalt, ruthenium, etc. metals are used as active metals. In the company›s two-step method, it is first prepared from the dry mixing of raw materials urea, sodium orthophthalic acid, cobalt salt and two other components by Ball mill at high temperature and with metal-phthalocyanine intermediate. After preparation of the metal-phthalocyanine intermediate, the sulfonation step is carried out by oleum. | Заявка на материалы |
| HDS Hydrodesulfurization Catalysts (Par-Hyd-Cat) | Refinement of gas and crude oil in special processes | First Chapter | Advanced Catalysts & Absorbents41Chemicals40 Hydrodesulfurization is a process in which sulfur-containing components present in crude oil or natural gas cuts used in petrochemicals are removed by reaction with hydrogen. This process results in the removal of nitrogen and oxygen along with the hydrogenation of aromatics and olefins; Therefore, the set of these processes is called hydrotreating. Heavy metals, aromatics and olefins can also be removed with the help of par-Hyd catalysts. Hydrotreating simply leads to the conversion of organic compounds containing sulfur, nitrogen and oxygen into hydrocarbons and hydrogen sulfide, ammonia and water, respectively. At the same time, it is possible to convert olefins and aromatics into saturated hydrocarbons without any cracking process on hydrocarbons. In fact, this process leads to the production of fuels with the lowest amount of sulfur and impurities. With the passage of time and heavier crude oil entering the refineries, the amount of sulfur compounds in the hydrocarbon cuts from the distillation tower has also increased. Environmental regulations based on the production of refined products, including gasoline and diesel, are compatible with quality and environmental standards in such a way that the permissible limit of pollutants is reduced every year; Therefore, refiners have been directed to use processes to reduce the amount of sulfur and polluting compounds in hydrocarbon cuttings. Due to the catalytic nature of this process, this product includes the catalyst used in these processes. | To make this type of catalyst, gamma-alumina is often used as a catalyst base. The active metal catalyst is nickel or cobalt and molybdenum, which is added to the catalyst base using various methods, including common Impregnation methods. It is worth mentioning that due to the existence of different cuts in an oil refinery, such as naphtha, kerosene, gas oil, and mazut, a special process and catalyst are used for each of these cuts. Naphtha catalysts include naphtha hydrotreating (NHT), kerosene hydrotreating (KHT) and gas oil hydrotreating (GHT) catalysts. The preparation of these catalysts consists of several steps: 1. Preparation of catalyst base or support, which is usually a formulation based on gamma alumina. (The company claims that it uses gamma alumina produced by the company itself). 2. Formation of the catalyst base 3. Drying and curing the catalyst base 4. Solubilization of catalyst salts, which are water-soluble salts of active metals (nickel, cobalt, and manganese). 5. Impregnation of the catalyst solution on the catalyst base 6. Heat treatment and final drying (removal of physical water) and calcination (removal of chemical water in meso and micro pores) of the catalyst | Заявка на материалы |
| Catalyst for Desulfurization of the Output Gas Streams of Claus Process with COS and CS2 Compounds (Par-Cata-Mond-Gas) | The properties of bentonite include: softness, swelling, relatively good ability to mix with water, pastiness, plasticity, adhesion and absorption. For this reason, this substance has many uses, which include: production of catalytic absorbent soil, drilling mud, softener of sanitary detergent powders, preparation of casting sand, bedding soil for pets, preventing water leakage in dams and water supply channel, clarifying agents for liquids such as juices and wine, clarifiers and other sprayable substances, preparation of plant and animal poisons, fillers in industries such as papermaking, production of cleaners and detergents, and preparation of all types of ceramics and paint removal and refining of all types of oils | First Chapter | Advanced Catalysts & Absorbents43Chemicals42 COS and CS2 compounds in the Claus process cannot be converted into molten sulfur and enter the environment as pollutants; Due to the new environmental standards, refineries and petrochemicals are not allowed to release these compounds. As a result, in order to eliminate these compounds, there is a need for a catalyst that can convert these compounds into H2S through the reduction process, and the produced H2S returns to the beginning of the Claus cycle and turns into elemental sulfur in the corresponding catalyst. | The catalyst is similar to HDS catalysts, whose active metals are nickel, cobalt and molybdenum based on alumina. But there are many differences both in the base (shape, size of holes, acidity level, extrusion and calcination methods) and in the type and amount of active metals. | Заявка на материалы |
| Cobalt-Manganese-Bromide (CMB) Catalyst Used in the Production of Terephthalic Acid with the Synthesis of Cobalt Acetate and Manganese Acetate | This catalyst is used to convert paraxylene to terephthalic acid in the polymerization processes of terephthalic acid with ethylene glycol to produce polyethylene terephthalate (PET). | CMB catalyst is a combination catalyst of three basic components of manganese, bromine and cobalt. This catalyst is in a red liquid state, which changes the ratio of these elements according to the type of technology used. This product is a liquid and homogeneous catalyst that enters the process and exits after playing a catalytic role. This catalyst is used to produce PET with different grades, including edible grade, as the primary polymer of liquid bottles (PET bottles). | This catalyst is a homogeneous and mixed catalyst that is used in modern PET production technologies in the world. In order to be effective and to produce the right product quality, this catalyst must have certain characteristics. One of the special features of this catalyst is its low corrosion rate, which reduces production costs. The second feature of this catalyst is its easy use and reduction of catalyst preparation steps for use. The third feature of this catalyst is its reasonable price compared to previous catalysts used in PET production industries. | Заявка на материалы |
| Vanadium Pentaoxide Catalyst | Vanadium pentoxide is one of the important catalysts used in chemical oxidation processes (such as production of terephthalic acid from paraxylene, production of sulfuric acid from sulfur in the presence of oxygen). This material is used as one of the important elements in the production of steel and other steel or aluminum alloys for use in the aerospace industry. Adding small amounts of this material to stainless steel alloys increases its strength 7 times | Vanadium pentoxide is a yellow solid mineral compound with the chemical formula V2O5, molecular mass 181.88 g/mol, density 3.357 g/cm3, melting point 690 °C and solubility 8 g/L at 20 °C. It turns orange when dissolved in water, and due to its high oxidation property, it is both an amphoteric oxide and an oxidizing agent. One of the most important steps in the production process of sulfuric acid and sulfonic acid is the oxidation of SO2 to SO3. Vanadium pentaoxide catalyst is used for this process. SO2 gas along with O2 and N2 gases are passed over the catalyst and during the passage over the catalyst, SO2 absorbs and performs oxygen exchange on the active sites of the catalyst. The result of this process is the conversion of the catalyst to SO3. | The production process of this catalyst, which is used as a fixed bed, includes the following four parts: 1. Preparation of the paste, which is a formulation of vanadium pentoxide silica or diatomaceous earth (the dominant part of the formulation), mineral binder which is mostly sodium silicate (glass water). 2. Forming the dough, which is in the form of an extruder. In this context, horizontal or vertical extruders can be used. 3. Drying 4. Calcination. This stage is very sensitive to the temperature profile, time control and heating speed, which is done continuously in the furnace. 5. Identification analyzes such as XRD, BET, SEM-EDAX, as well as functional analyzes such as compressive strength, scratch resistance, density, capacity, strength and absorption speed have been performed by the company. | Заявка на материалы |
| Vanadium Pentoxide Protective Catalyst Used in the Production of Sulfuric Acid and Sulfonic Acid | Sulfuric acid and sulfonic acid production factories | In sulfonic acid production plants, such as the production of detergent raw materials (such as linear alkyl benzene sulfonated (LABS) and sulfuric acid), especially metallurgical units that have heavy metals, toxic gases and moisture, the expensive V2O5 catalysts of the main reactor are subject to poisoning, pulverization and pressure drop. As a result, it causes expensive shutdowns of acid plants, high electricity consumption of blowers and reduced profitability. One of the reasons for the failure and rapid pressure drop of these catalysts is the entry of toxic polluting elements (fluorine, chlorine and arsenic) which causes the loss of the adsorbent, reducing its activity, pulverization and increasing the pressure drop. One of the reasons for the failure and rapid pressure drop of these catalysts is the introduction of toxic polluting elements (fluorine, chlorine and arsenic). These elements cause the loss of the adsorbent, decrease its activity, pulverize and increase the pressure drop. The use of protective catalysts makes the toxic pollutant elements to be removed before contact with the main catalysts, and the problem of pressure drop is eliminated and less pressure is applied to the blower. As a result, in addition to reducing electricity consumption, the catalysts are less damaged and the life of the catalysts increases. | Protective catalysts are used in the first to fifth beds of reactors of sulfonic and sulfuric acid plants, depending on the single or double absorption process system. In case of single absorption in the first bed of the reactors, due to the use of diesel when heating the converter, 5 to 7 cm (depending on the process conditions) of catalyst is used; This amount is three centimeters in other beds. In double absorption processes, if the process system is 3+2 or 7 ,1+4 cm of protective catalysts are poured into bed 4 or bed 5. The reason why more catalysts are used in these beds is to prevent the sulfuric acid vapor that has passed through the demister pads in the absorption tower. In this situation, protective catalysts play the role of protection and safety shield. The creativity of the company in the development of this product is that, in fact, the manufactured product has the ability to completely replace the original catalyst, and with the improvements made by the company, it plays both the role of a catalyst and a protector. | Заявка на материалы |
| Catalytic Converter in Automotive Exhaust | These catalysts, which are installed as a set on the car, have the task of converting the pollutants coming out of the exhaust into less dangerous substances. Therefore, these catalysts are generally installed on passenger cars, heavy vehicles and motorcycles. | Generally, Catalytic Converters are made of silicon carbide (rarely) or aluminum oxide and silica; Inside the catalyst, precious metals have been coated and increased the price of the catalyst. Automotive catalysts are mainly installed in two ways: UNDER BODY at a distance of 1 to 1.5 meters from the engine or CLOSE COUPLED with direct connection to the exhaust manifold. In the second case, the pressure, temperature, and abrasion are higher, and as a result, the stress on the part is higher. On the other hand, placing the monolith and mat inside the shell (canning) can be done as a clam shell (opening the shell and placing the catalyst and welding) or hard stuff (the monolith is inserted into the shell through a funnel). | The core of the catalytic converters of all domestically produced cars made by this company is made of ceramic material. Metal core is used for motorcycles and expensive foreign cars. The coating, which is prepared in the operation and is also called washcoat, includes basic, enhancing and stabilizing materials, as well as catalyst metal salts, which are from the group of precious metals: palladium (Pd), platinum (Pt) and rhodium (Rh), which are known as PGM metals. In the production process, washcoat materials are first produced based on specific formulations, including base materials, enhancers, stabilizers, and precious metals. Then the pulsed laser deposition of the washcoat material on the core (monolith) is done through the suction or blowing process by air pumps, and after the drying and calcination process, the coated monolith is placed in a thermal-mechanical insulator and then covered with metal. Therefore, this product or catalyst is very effective in reducing air pollution. The triple catalytic converter performs the following three tasks: a) reduction of nitrogen oxides to oxygen and nitrogen through the reaction: NOx → xO2 + N2 b) Oxidation of carbon monoxide to carbon dioxide through the reaction: CO + 2/1O2 → CO c) Oxidation of unburned hydrocarbons and their conversion into carbon dioxide and water through the reaction: CxH2x+2 + [(3x+1)/2] O2 → xCO2 + (x+1)H2O | Заявка на материалы |
| Chlorine Absorber (Chlorine Guard), Mercury Absorber (Mercury Guard) and Arsenic-Phosphine Absorber | All the mentioned impurities are absorbed by chemical adsorbents and removed from the feed stream or output product. | In naphtha reforming units (CRU & CCR), noble metal catalysts based on chlorinated alumina are used to increase the octane number of naphtha cuts. The presence of chlorine in the composition of such catalysts is essential. But the noteworthy point is that after a while and after the passage of the hydrocarbon flow, some chlorine is separated from the catalyst surface, and this chlorine is observed in the gas (hydrogen) and liquid (hydrocarbon cut) output flow, where it is generally in the form of inorganic chlorine (HCl) and organic chlorine (R-Cl). Crude oil and gas condensates extracted from reservoirs contain amounts of various metals (including mercury). In addition to safety and biological issues, the presence of mercury in these streams causes several process problems: corrosion in transmission pipes, loss of performance of catalysts in various units, and destruction of aluminum parts in converters. The presence of pollutants such as arsenic and some phosphorous compounds including phosphine in the feed of petrochemical units, even in very small amounts, can cause a decrease in process efficiency and permanent poisoning of downstream catalysts. Therefore, the complete removal of these compounds from process streams is always one of the challenges in the petrochemical industry. Among the various arsenic compounds, arsine with the chemical formula AsH3 is the simplest and at the same time the most common compound found in hydrocarbon streams. Due to its greater abundance compared to others, the oil and gas industry usually considers all arsenic content in streams to be arsine. The presence of this substance in polypropylene units even at the ppb level can cause poisoning of expensive catalysts in downstream units | Among the various methods that currently exist to remove the mentioned compounds, surface absorption with low cost and a simple process is able to completely remove these compounds. All of the company‘s products are based on active alumina, and other salts are added to the absorbent base according to the desired impurity in the hydrocarbon streams | Заявка на материалы |
| Hydrogen Sulfide Absorbent Based on Triazine Synthesis (Tachem 3040) | Oil and gas industry | Hydrogen sulfide adsorbents or H2S Scavenger are a group of materials that are widely used in the oil and gas industry. These materials specifically react with hydrogen sulfide and remove it from the environment. Hydrogen sulfide causes a lot of damage to transmission lines, chimneys, or other systems. It can also react with steel and produce a thin film of its sulfide and cause corrosion. When this gas dissolves in water, it produces sulfur, which can also cause corrosion. Therefore, removing this gas is necessary and important. Hydrogen sulfide is naturally present in crude oil and is also produced in oil refining methods such as hydrocracking or hydrolysis. But to remove it completely or to remove it from the exhaust gas of chimneys, hydrogen sulfide scavengers or absorbers can be used | The company›s product belongs to the category of water-soluble cleaners, which are the most common hydrogen sulfide cleaners and are used at temperatures below 90°. This company‘s product is based on triazine and is a light brown liquid product, and every 10 ppm of it is able to remove 1 ppm of H2S. | Заявка на материалы |
| Adsorbent Used in the Purification of All Types of Transformer and Turbine Oil on an Industrial Scale Based on Processed Bauxite | The product is the result of thermal and chemical processing of mineral bauxite, which is used for the physical and chemical adsorption of various colored impurities and sulfur-containing compounds in used oils. | According to the definition of the IEC standard, the chemical treatment of oil is the removal of any polar and chemical contamination of the oil, including acids, aldehydes, ketones, esters, and aromatic compounds. This process improves the chemical parameters of the oil, including neutralization number (acidity), surface tension, loss coefficient and oil color. The oil after purification must meet the criteria and conditions described in the IEC 60296 standard. | The adsorbent must have a high specific surface and porosity so that it can adsorb a large amount of impurities in the oil. In addition, the adsorbent should have high thermal stability so that it does not lose its structure in different stages of adsorption and regeneration and maintains its efficiency. The second aspect of the design is the adsorbent regeneration system, in which the amount of oxygen needed for regeneration should be determined according to the structure and type of pollution, and the regeneration control and monitoring system should be designed accordingly. The regeneration process starts by heating the upper part of the adsorber to the ignition temperature of the polluting compounds and then injecting air, and then this process of burning continues along the adsorber bed. Controlling the temperature profile during the regeneration process is very important, and if these conditions are inappropriate, the regeneration process will either stop, or too much heat will be produced and the adsorber will be damaged.The adsorbent used in this product is Active Alumina, which is prepared from the natural source of bauxite. For this, an acid leaching step with hydrochloric acid is performed to remove impurities of iron (hematite), calcium and magnesium, and then two heating steps are performed. Bauxite is first transformed into boehmite and then into gamma alumina or active alumina with an average surface area of 150 cubic centimeters per gram of adsorbent. Next, this product reacts with acid and its main impurity, i.e. iron, is removed | Заявка на материалы |

Due to its greater abundance compared to others, the oil and gas industry usually considers all arsenic content in streams to be arsine. The presence of this substance in polypropylene units even at the ppb level can cause poisoning of expensive catalysts in downstream units | Among the various methods that currently exist to remove the mentioned compounds, surface absorption with low cost and a simple process is able to completely remove these compounds. All of the company‘s products are based on active alumina, and other salts are added to the absorbent base according to the desired impurity in the hydrocarbon streams | Заявка на материалы |
| Hydrogen Sulfide Absorbent Based on Triazine Synthesis (Tachem 3040 | Oil and gas industry | Hydrogen sulfide adsorbents or H2S Scavenger are a group of materials that are widely used in the oil and gas industry. These materials specifically react with hydrogen sulfide and remove it from the environment. Hydrogen sulfide causes a lot of damage to transmission lines, chimneys, or other systems. It can also react with steel and produce a thin film of its sulfide and cause corrosion. When this gas dissolves in water, it produces sulfur, which can also cause corrosion. Therefore, removing this gas is necessary and important. Hydrogen sulfide is naturally present in crude oil and is also produced in oil refining methods such as hydrocracking or hydrolysis. But to remove it completely or to remove it from the exhaust gas of chimneys, hydrogen sulfide scavengers or absorbers can be used | The company›s product belongs to the category of water-soluble cleaners, which are the most common hydrogen sulfide cleaners and are used at temperatures below 90°. This company‘s product is based on triazine and is a light brown liquid product, and every 10 ppm of it is able to remove 1 ppm of H2S. | Заявка на материалы |
| Adsorbent Used in the Purification of All Types of Transformer and Turbine Oil on an Industrial Scale Based on Processed Bauxite | The product is the result of thermal and chemical processing of mineral bauxite, which is used for the physical and chemical adsorption of various colored impurities and sulfur-containing compounds in used oils. | According to the definition of the IEC standard, the chemical treatment of oil is the removal of any polar and chemical contamination of the oil, including acids, aldehydes, ketones, esters, and aromatic compounds. This process improves the chemical parameters of the oil, including neutralization number (acidity), surface tension, loss coefficient and oil color. The oil after purification must meet the criteria and conditions described in the IEC 60296 standard. | The adsorbent must have a high specific surface and porosity so that it can adsorb a large amount of impurities in the oil. In addition, the adsorbent should have high thermal stability so that it does not lose its structure in different stages of adsorption and regeneration and maintains its efficiency. The second aspect of the design is the adsorbent regeneration system, in which the amount of oxygen needed for regeneration should be determined according to the structure and type of pollution, and the regeneration control and monitoring system should be designed accordingly. The regeneration process starts by heating the upper part of the adsorber to the ignition temperature of the polluting compounds and then injecting air, and then this process of burning continues along the adsorber bed. Controlling the temperature profile during the regeneration process is very important, and if these conditions are inappropriate, the regeneration process will either stop, or too much heat will be produced and the adsorber will be damaged. The adsorbent used in this product is Active Alumina, which is prepared from the natural source of bauxite. For this, an acid leaching step with hydrochloric acid is performed to remove impurities of iron (hematite), calcium and magnesium, and then two heating steps are performed. Bauxite is first transformed into boehmite and then into gamma alumina or active alumina with an average surface area of 150 cubic centimeters per gram of adsorbent. Next, this product reacts with acid and its main impurity, i.e. iron, is removed | Заявка на материалы |
| Bentonite Active Absorbent of Olefinic Compounds from Aromatic Products (Par-Tonit | Bentonite as a porous material is easily and abundantly found in nature. The possibility of using it as an industrial adsorbent and catalyst always exists and this field is the subject of many researchers› discussion. Activated bentonite is used as an active absorbent soil or color removal soil in various industries due to its specific surface area and high surface acid strength. The presence of olefins in aromatic compounds (benzene, toluene, xylenes) even in very small amounts can make these valuable intermediates of organic and petrochemical synthesis lacking desirable characteristics; Because under the relatively harsh conditions required for aromatics to continue industrial reactions, olefins, which are more reactive than aromatics, contaminate catalysts or create unwanted byproducts. On the other hand, since the amount of aromatic compounds in crude oil is much less than the increasing industrial needs, these valuable compounds are synthesized by the catalytic conversion process. In such a process, some olefin is inevitably produced. Although most of it is separated by distillation and solvent extraction, small amounts of olefin remain, and the deolefinization process by means of solid beds of activated bentonite is the only economic method for its complete removal. | Bentonite as a porous material is easily and abundantly found in nature.

| Electrolyte Fluoride Salts (NaF, LiF, MgF2, CaF2, AlF3 and Na3AlF6) Used in Aluminum Production Process | These salts cause the melting temperature of aluminum to decrease in the process of producing this material electrochemically | One of the most important and economic industrial methods of aluminum production is the Hall-Heroult process. In this method, alumina is used as a raw material. This material, along with other additives, is reduced to molten aluminum metal inside the electrolyte solution and using electric current at high temperatures (about 900 to 1000 °C). Then the molten aluminum is presented through cold molding for further use. One of the main problems related to the production and electrolysis of aluminum in the Hall-Heroult process is the high melting temperature of alumina. The actual melting temperature of this material is 2000 °C. Various additives are used to reduce the melting temperature to 900 °C and thus reduce energy consumption and production costs. | Electrolytic additives in the above process are aluminum fluoride, cryolite, calcium fluoride, lithium fluoride, sodium fluoride and magnesium fluoride. Basically, all these products are the result of the reaction of oxides (mostly magnesium), hydroxides (mostly aluminum) or carbonates (lithium, calcium, sodium) of the mentioned metals with hydrofluoric acid. All mentioned salts must be of high purity so that they don’t cause any disturbance in the aluminum production process | Заявка на материалы |
| Green Rubber Process Oil in Three Grades Gr-15, Gr-20, Gr-40 | This oil is used in the tire production process. | In the tire and rubber industry, process oils are used to create rolling resistance, thermal resistance, and ease of processability. These oils were usually the output of the process units of oil factories and the result of purification by furfurals, whose polyaromatic content is very high and causes cancer. With the establishment of new standards, the amount of polyaromatic compounds in these oils should reach below 3 ppm. The product is an oil cut whose polyaromatic compounds are below 10 ppm (about 7 ppm). | In the production of this product, the focus is on the selectivity and separation of polycyclic compounds based on the molecular structure of the feed. Due to the fact that the process is completely selective and the feed is selected as lube cut, which has the appropriate molecular composition and basic structure, it is possible to obtain a suitable product with the desired properties only by separating the desired compounds and not involving other useful molecules in the oil. There are also aromatic, paraffinic and naphthenic hydrocarbon compounds in the structure of lube cut. In the solvent extraction process, it is tried to separate all aromatics affected by the liquid-liquid extraction method from the paraffin tissue according to the type of solvent.

| Mineral Based Grease other than Bentonite Including Silicone and W1000 | Polyurea greases are prepared by thickening mineral oil or synthetic oil with organic compounds containing polyurea groups in the molecule. Polyurea thickeners are different from soap-based metal (calcium, sodium, lithium) thickeners and do not contain any metals. Typically, their operating temperature range is higher than greases based on metal soaps. Due to the nature of polyurea, they have better anti-oxidation and anti-abrasion properties. Their other advantages are: pumpability, oxidation resistance, mechanical stability, colloidal stability and water washing, high temperature and load tolerance. Polyurea grease has very good wear resistance and prevents direct contact with the surface of the teeth, so it can effectively extend the service life of the device. | Grease, according to the definition of the American Materials Testing Association (ASTM), is a semi-solid or solid combination of petroleum derivatives, a soap or a combination of soaps and a suitable filler that has a high viscosity and is produced for a specific type of lubrication. | Grease components include the following three parts: ٭ Base oil Most of the greases produced from mineral oil are derived from petroleum. These oils provide satisfactory performance in many industrial applications due to their ability to work at high or low temperatures. It should be noted that synthetic oils are also used for special applications. ٭ Thickener A thickener is a substance that, in combination with the base oil, produces a solid semiconductor structure. Often, the type of thickener used in metal-based greases is called metallic soap. This soap contains lithium, aluminum, clay, polyurea, sodium and calcium. Nowadays, complex thickeners have gained a lot of popularity in grease production due to their higher temperature tolerance and higher load tolerance. The most common complex grease is based on lithium, which is known as lithium grease. These types of greases are made with a combination of ordinary lithium soap and low molecular weight organic acid as a thickening agent. Non soap thickener is essential for use in high temperature environments. Bentonite and silica are two examples of soap-free thickeners that do not melt at high temperatures. Although the thickener is able to withstand high temperature, but because the base oil oxidizes quickly at high temperature, exposure of this thickener to high temperature for a long time will be associated with unfavorable results. ٭ Additives Grease additives are used with the purpose of improving and increasing desirable properties, reducing undesirable properties or creating new properties in grease. The most common grease additives are used to prevent oxidation, prevent rust and reduce friction | Заявка на материалы |
| Emulsifying Oils (Antimicrobial) Used for Machining of Parts | These materials have been developed mainly in the machining of metal parts to lubricate the machining process. | In many industries, emulsions of organic substances in water, such as oils, waxes, and solvents, are used for various processes. Among these industries, we can mention metal turning, textile, tanning, etc. However, oil and water emulsions are an ideal place for microbial growth, and for this reason, they spoil in a short time and lose their functional properties. The increase of the microbial population, especially in anaerobic conditions, causes the degradation of emulsions, the creation of odors, the reduction of pH, and the separation of oil and water. Heavy growth of fungi leads to clogging of components, such as fluid transfer pipes, and may also have harmful effects on workers’ health. It should be noted that the amount of degradation caused by microorganisms depends on factors such as the type, population, physical condition of the system such as temperature, cleanliness, type of water used and the age of the emulsion. | The presented product is an emulsifiable oil with a paraffin base and biological technology, which is designed and produced for machining parts with ferrous and non-ferrous alloys. The general idea of this method is to use a suitable substrate and selective growth of a less harmful microorganism species in the emulsion environment as the dominant species. For this purpose, a harmless type of aerobic bacteria is added to the product from the beginning, so that it does not allow them to grow by competing with the fungi. | Заявка на материалы |
| Emulsion Oil for Cold Rolling Mill of Steel Sheet in Three Types Single, Double and Five Row | Used as lubricant in cold rolling mill process | Cold rolling mill oils are special lubricants that are used to control the friction between the rollers and the sheet, as well as remove the heat generated in the cold rolling process of the sheet. These products are usually a mixture of synthetic hydrocarbons and additives. They are used in the form of emulsion and they facilitate the reduction of the thickness of the sheet and reduce the forces required for the rolling process. Excellent lubrication quality, super cleanliness of the sheet surface due to the washing nature of the emulsion, uniform and stable rolling, increasing the speed of the rolling process and the production rate, complete evaporation in the annealing process, cleaning the rolling unit chamber, and reducing the friction of the roller are some of the features of this product. | The most important challenge in the process of reducing the thickness of the sheet is the high heat caused by the movement and sliding of the molecules on each other. The quality of the resulting product is a function of oil polarity, particle size in the emulsion, its uniform distribution, the layer deposited during the process, thermal and chemical stability, and optimizing the process to achieve desired qualities is one of the most important challenges of producing a high-quality product. | Заявка на материалы |

Soybean oils contain high amounts of fatty acids that can be converted into epoxy fatty acids. | To produce this product, the epoxidation process must be done. In terms of kinetic engineering, this reaction is considered one of the complex processes on an industrial scale, and it is in great need of control. This process has many complications, some of which are: precise and sensitive temperature control, control and regulation of reaction mixing, raw material control (saponification value, iodide number and color), biphasic reaction, sewage management and epoxy instability under acidic conditions. | The reaction is carried out by oxygenated water and in the presence of a transfer agent such as acetic acid or formic acid, we get a peroxide. Peracid is highly active and explosive. Reaction control and reproducibility are very important with this product.

| Polyisobutylene Succinimide Dispersant Additive Used in Engine Oil | Dispersants include two heads: a polar head and a non-polar head (soluble in oil). The polar heads of the dispersants attack and surround the desired pollution and by forming a ring, they keep the pollution suspended in the oil and prevent it from connecting with the metal body of the engine. | Dispersants are used as one of the essential additives in the lubricant industry. These compounds have the task of cleaning the engine body, so there is no contamination on metal surfaces. This contamination on metal surfaces creates an acidic environment and severely reduces the quality of engine oil or any other lubricant. Dispersants keep these contaminants, which may be caused by the thermal degradation of the lubricant or the decomposition of additives, or other cases, in a suspended and so-called dispersed form in the lubricant space. When the oil is changed, these contaminants are removed along with the oil. One of the reasons for the darkening of the engine oil after consumption is this, which indicates the excellent quality of the oil because it has been able to keep the pollution suspended in it.

Machining lubricants are divided into three categories according to the type of operation and conditions of the part and tool: pure oils, emulsifying oils, and soluble gel and solid oils. Gel-soluble and solid oils are similar to liquid-soluble oils in many ways, and they all dissolve in water. Their difference is that these oils are solid or semi-solid and are used for machining processes. The optimal performance of solid soluble oils is as follows: the lubricant stays on the part and melts with the heat from machining and performs cooling and lubrication. | The introduced product has many components that should be optimized according to the final performance of the product.

| Polyurethane Mold Release Wax (POLYBON) | Separating wax plays an essential role in polyurethane foam production industries, among which we can mention: car insulation foam production industries, car seats, and home and office furniture production industries | The production process of polyurethane foams is by injecting materials into the mold, and separating wax acts as an important component in the final stage of polyurethane foam production. This process is such that after the completion of the curin process and the growth of the foam inside the desired mold, the separating wax comes into action and the desired foam can be easily separated from the surface of the mold even with a very low thickness. In case of improper performance of the separating wax, the adhesion of the foam on the surface of the mold and the tearing of the desired foam will occur. The result is that the produced foam becomes waste, and in addition, it is no longer possible to recycle it. The surface of the mold must also be cleaned for the next production, which causes the production line to stop and waste a lot of time. | The final product of the company is a dispersion in solvent-based media (both water-based and solvent-based) that is applied on the surface of the mold. This product forms a very thin film (Thin Film) with a nanometer thickness on the surface of the mold, which causes the separation of the polyurethane foam after the curing process and the complete growth of the foam.

In nanomaterials, epoxidized soybean oil is used as a coating layer on the surface to disperse nanoparticles and keep them in a colloidal state through the mechanism of electrostatic repulsion or spatial repulsion. Another important and abundant use of epoxy soybean oil is to use it as the main intermediate in the production of polyols used in polyurethane industries. | Epoxidized vegetable oils are of great importance in chemical industries and commercial products as a renewable intermediate material with biodegradability. Vegetable oils are used as a green raw material in the production of this epoxy intermediate material. In this way, it is possible to use in chemical, polymer, paint and cosmetics industries. The epoxidation of oils in the industry is based on a set of complex reactions between oil and peracetic or performic acid. Moreover, this reaction is generally reactive in situ through controlled mixing of hydrogen peroxide with a carboxylic acid in the presence of acid catalysts. | To produce this product, the epoxidation process must be done. In terms of kinetic engineering on an industrial scale, this reaction is considered one of the complex processes and needs to be controlled. Accurate and sensitive temperature control, control and regulation of reaction mixing, raw material control (soap number and iodide number and color), biphasic reaction, waste management, instability of epoxy in acidic conditions are among the complexities of the product production process. For example, if the soap number is high, it will play the role of emulsifier, which causes mixing of water and oil phase, which is not desirable. The reaction is carried out by hydrogen peroxide, which turns into a peroxide in the presence of a carrier such as acetic acid or formic acid. Peroxide is very active and highly explosive. Reaction control and repeatability are important considerations for this product. | Заявка на материалы |

In all machining operations such as turning, milling, drilling, cutting, the heat caused by the friction of the tool and the workpiece causes them to be destroyed. This problem can be avoided to a great extent by using cooling and soapy fluids. | Industrial lubricant solutions must have several important features: ٭ Have a high flash point and thermal tolerance, be able to absorb and dissipate the high heat of metalworking operations (cutting, drilling, etc.) well so that there is no problem for the part and it does not evaporate or catch fire. Also, at low and sometimes negative temperatures, the product should not freeze and lose its properties. ٭ Have high stability against biological spoilage through different microorganisms, bacteria, fungi, etc. Otherwise, there will be a bad smell in the environment and a decrease in product efficiency. ٭ have high stability against two phases and losing the stability of their emulsion. One of the reasons for the transformation into two phases is biological corruption. ٭ Do not cause the destruction of metalworking equipment such as rust, corrosion and clogging (jamming) of the device and have the ability to mix with water of different degrees of hardness. ٭ Creating a strong interface leads to improvement of mechanical properties such as impact and tensile strength and improvement of adhesion. ٭ Formulations of industrial lubricants are usually based on vegetable or mineral oils emulsified in water through ionic and non-ionic emulsifiers. To solve the problem of corruption and corrosion, biocides such as benzalkonium chloride and anti-corrosion compounds such as zinc compounds are used in the formulation, respectively. | Заявка на материалы |
| Motor Oil Based on Diamond Nanoparticles | This product is used as car engine oil. By changing the properties of this product, it can also be used as an industrial oil. | Oil containing diamond nanoparticles is obtained from the combination of base oil, common oil additives and diamond nano solution.

In addition, the use of this oil in engines will reduce fuel consumption and also reduce engine pollution. | Adding nanodiamonds does not cause any changes in the physical and chemical properties of the oil (viscosity, ignition temperature, etc.); Rather, we see the effects of these nanoparticles in the performance of oil in the engine. Assume the inner wall of the cylinder of a car that is in contact with the piston: only the space between them is filled with engine oil to reduce the friction and facilitate the movement of the two relative to each other, but on these contact surfaces, cracks or scratches It is very narrow which cannot be avoided. These thin grooves cannot be removed with any device and the surface can be polished. Since nanoparticles are very small (3 to 6 nanometers), they create a coating and a resistant film layer on the surfaces, and over time, they smooth and polish the surface and reduce the friction coefficient, and as a result, the engine works more smoothly. In this way, fuel consumption and energy loss are reduced and the speed and acceleration of the car increases. In order to prove that, the friction coefficient reduction test has been done. Also, samples of parts covered by gear oil and their radiographic images were taken. | Заявка на материалы |

Commonly used oils contain polycyclic aromatic compounds (PCA) and these compounds are carcinogenic and very dangerous for human health. Green oil product is produced by normal RPO processing and by extracting harmful substances from RPO. Since 2010, European countries, North America, Korea and Japan have decided to create a standard for process oil, based on which it was decided that normal process oil will be changed to “green” or environmentally friendly process oil. Today, in European, American, Korean and Japanese countries, the use of normal tires and normal process oils is obsolete, and a product that does not have the label of green tires is not allowed to be used in these countries. | The design of the extraction process and system, the amount of solvent, the type of solvent and the stoichiometric ratio of oil/solvent, different temperature diagrams are some of the technical complications in the extraction process.

| Emulsifiers Used in Food Industry | In the food industry, including modifiers of bread and pastry, yeast dough, sweets and chocolates, cakes and cookies, meat products and etc | Emulsifier compounds are of the subcategory of surface active agents or surfactants. In other words, emulsifiers are fatty substances that have dual properties of lipophilic and hydrophilic. The surface tension between two phases that are normally immiscible is reduced by emulsifier. Therefore, two liquids will be able to form an emulsion. An emulsifier contains water-soluble and oil-soluble parts. When an emulsifier is added to a mixture of water and oil, it is placed on the contact surface between the two. This is done in such a way that the hydrophilic part is inclined towards water and the lipophilic part is inclined towards oil. | The general raw materials used in the synthesis of emulsifiers are the same and include glycerol radical (monoglyceride, diglyceride, etc.), acid radical (tartaric acid, acetic anhydride, acetic acid, lactic acid), catalyst and anti-agglomeration agent. According to the use of emulsifier in the final product (food industry), the expected final soap number and acidic number, the type of acidifying agent, catalyst, glycerol radical are changed. Also, the process variables including temperature, time, and pressure are changed accordingly and optimized according to the considered emulsifier. | Заявка на материалы |
| Demulsifier | These materials cause the separation of water from the water/oil emulsion and prevent problems such as corrosion, difficulty in transferring oil and reducing the quality of oil. | By using several methods such as mechanical methods (including filtration, thermal treatment techniques and even membrane separation), thermal, chemical or even electrical methods, water dispersed in oil can be separated. Determining the characteristics of the emulsion is important to identify the best method to use. Among the mentioned methods, the best and most economical method is the chemical suspension process. Based on this, a suitable demulsifier with the lowest possible concentration should be used, which can completely separate the water at a low operating temperature and reduce the salt to the lowest possible level in the shortest possible time. | The demulsifier breaks the water-in-oil emulsion and separates the water from the produced oil. The demulsifier, in contact with the water-in-oil emulsion, weakens the electrostatic forces of repelling water droplets and eventually causes the droplets to collect together. This process includes the following two steps: ٭ Flocculation: tiny water droplets are connected to each other and appear in the form of clusters. ٭ Coagulation: binding of water molecules. Solid wetting: With this process, physical separation takes place and water is placed at the bottom. It is necessary to investigate various factors affecting the performance of demulsifiers, such as the rheology of interfacial properties, the amount of hydrophilicity and hydrophobicity, the rate of mass transfer from the demulsifier to the interface, etc. One of the characteristics of a suitable demulsifier is the maximum separation of water from crude oil with the minimum amount and concentration of demulsifier used at the lowest operating temperature and the shortest time. Demulsifiers are a combination of different materials, including acid or base catalyzed phenol formaldehyde resins, polyols, polyamines, polyethylene imines and even epoxy resins. The main component of these materials is based on polymer or copolymers, which must be ethoxylated or propoxylated in a controlled manner before use. The product is a formulation of one or more of the aforementioned ethoxylated or propoxylated polymers along with some additives, including alkyl aryl sulfonic acids, fatty acid esters, ethers and esters of bis-phenol glycol, sodium dodecyl sulfate, etc. These additives are soluble in solvents such as xylene, heavy aromatic naphtha, isopropanol, methanol, ethylhexanol, etc. Their composition is done in certain percentages, which need to be changed according to the specifications of the oil extracted from each oil field. | Заявка на материалы |
| Demulsifier | DEMULSIFIERS or emulsion breakers are special chemicals that play an important and strategic role in the separation of oil-related materials. These materials overcome the water-oil emulsion and lead to the separation of water from oil. | Due to the presence of high amounts of water, salt and other solids in crude oil, it is necessary to separate these materials from crude oil in primary extraction before refining crude oil; Because the presence of these materials, especially water, which also carries some dissolved salt with it, has led to a decline in the quality of oil in the world market and will even cause it not to be purchased if the permitted amount is not met. One of the most important problems created in case of no separation or insufficient separation of water and soluble salts from oil is the creation of severe corrosion problems of crude oil refining equipment | Mostly, demulsifiers are a combination of different materials including acid and/or base catalyzed phenol formaldehyde resins, polyols, polyamines, polyethyleneimines and even epoxy resins.

| Kinetic Inhibitor to Prevent Hydrate Formation Based on Phenol Formaldehyde Resin | As an inhibitor of hydrate formation in oil and gas pipelines | Natural gas and crude oil are naturally in contact with water in underground reservoirs. Water molecules form a quasi-network structure due to having strong hydrogen bonds by creating holes. In the formed crystal network, gas molecules (guests) with molecular diameters smaller than the diameter of the holes are trapped inside the shelves created by water molecules (host) and by hydrogen bonds between them and due to the interaction between guest and host molecules, the created structure becomes stable. This formed crystalline substance, which resembles ice, is known as gas hydrate. Hydrate formation is a serious and essential factor in clogging process equipment and pipes in oil extraction, production operations in the petrochemical industry and refineries, as well as in gas transmission lines under low temperature and high pressure conditions. In the past decades, various types of hydrate inhibitors have been developed based on thermodynamic and kinetic changes. | The most important and newest hydrate inhibitor compounds that have been considered, instead of changing the thermodynamic conditions of hydrate formation, change the kinetics of its formation by slowing down the nucleation process and crystal growth.

| Corrosion Inhibitor | Almost all organic molecules used as corrosion inhibitors in oil and gas are highly polar and mainly nitrogen-based (such as amines, amides, imidazolines and quaternary ammonium salts). Nitrogen-based organic inhibitors such as polyamidoamines and imidazolines and their salts have been successfully used in this type of applications. The mechanism of action of this type of material is their sur- face absorption on the metal surface and creation of an interface layer. The ability of these compounds to create cations causes their strong surface adsorption on negatively charged surfaces such as metals and turns hydrophilic surfaces into hydrophobic ones. With this action, cathodic and anodic reactions are prevented. This product is used to prevent corrosion in tubing and wellhead equipment of oil wells and oil and gas fluid transmission pipelines, transmission and process systems related to sour water (such as stripping towers), process equipment (such as the overhead of distillation towers in the oil and gas, refining and petrochemical industries, which have a high H2S content (25% or higher)). | CO2 and H2S gases and chlorine and cyanide impurities in oil and gas cause corrosion of pipes and equipment made of carbon steel.

It is used as an anti-corrosion additive in oil, gas and petrochemical industries, power plant industries and treatment plants and other related industries (in general, industries where the presence and transfer of water leads to corrosion of their metal parts) | Anticorrosives are chemical substances that react with the surface of metals or are placed as a single layer around the surface subject to corrosion to partially protect the surface of the metal from the agents that cause corrosion of metals. Anticorrosives often protect the surface of metals by adsorbing themselves on the surface of metals and forming a film. They also reduce the corrosion process by increasing the behavior of anodic and cathodic polarization, reducing the transfer or diffusion of ions on the surface of metals and increasing the electrical resistance on the surface of metals. The systems used by the industry include metals such as iron, zinc, aluminum, steel, copper, etc. These metals may be used in various systems such as boilers, engine cooling systems, etc. In addition, these systems are in contact with acids such as hydrochloric acid, sulfuric acid, phosphoric acid, etc., or with water that has a lot of solutes and salt, all of which cause corrosion of these metals. Among them, there are chemical compounds that reduce the severity of corrosion, and each of these compounds is used with specific percentages for specific metals. Some of these compounds include: tripolyphosphates, imidazolines, sodium nitrite and mercaptobenzotriazole, borax, etc. Depending on the type of system used, corrosion inhibitors are divided into three categories: soluble in water, soluble in oil, and three-phase corrosion inhibitors. | Density: 1.3 to 1.7 (depending on the concentration of the active substance in the water solvent) ٭ Appearance: clear, yellowish to syrupy (depending on pH) ٭ pH: 8 to 9 for a %1 solution in water ٭ Solubility: It is completely soluble in water in any ratio.

| Simultaneous Inhibitor of the Formation of Calcium, Strontium and Barium Sediments Inside the Well and Oil Transfer Pipes | SCALE INHIBITOR is used to prevent the formation of calcium, barium and strontium sediments (carbonate and sulfate of these metals) etc. in oil wells and oil fluid transfer pipelines | To remove sediment and clogging, strong chelating and complexing materials are used with these cations to prevent the formation of insoluble carbonate and sulfate deposits. The formation of sediments of these compounds, such as calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate, causes clogging of pipes, reduction of oil production, increase of extraction and transportation costs, and as a result, heavy costs are imposed in order to remove this sediment.Phosphonate base compounds as well as polymers and copolymers based on acrylic acid are the most important and common compounds that have strong phosphonic and carboxylic acid chelating agents in their structure and form strong and soluble complexes with the desired cations and as a result prevent the formation of insoluble sediments of these compounds.

Another application of seawater antisediment is the use of these compounds as anti-scalant materials for waters with a high concentration of calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, and bicarbonate ions in the reverse osmosis (RO) system. This work is applied before the water enters the membranes as a suitable pretreatment system based on the quality of the feed water, and its purpose is to maintain the efficiency of industrial water treatment devices and increase the life of the membranes. Also, due to their relatively high stability in environments with high alkalinity, sea water anti-sedimentation is suitable for the preparation of household and industrial detergent products, which require the use of materials with strong performance. | Considering that most oil facilities are built by the sea, it is very important to use anti-sediment materials before seawater enters the facility due to the high level of salts and chemicals. Also, the formation of organic and inorganic sediments during crude oil production has always been one of the most important and common problems in the oil industry. This challenge can lead to interruption of flow and occurrence of various problems in various stages of production up to oil storage tanks and export. Since the first step in the occurrence of this problem is the formation of sediment inside the column of oil wells, therefore, chemical methods and continuous injection of anti-sediment chemicals with special efficiency can play a vital role in preventing corrosion caused by sedimentation and reducing its huge costs. | The product has been developed on the basis of phosphate ester called trietha-nolamine tris (dihydrogen phosphate) and is supplied as 50% soluble in water | Заявка на материалы |

This solution has different types and is used in systems such as cooling towers, condensers, boilers, chillers and absorptions, engine houses, packages and all systems that use water for heat transfer. | Converters are devices that are used to transfer heat. These devices have different types and are widely used in light and heavy industries, high-rise buildings (engine houses), refineries and petrochemicals, etc. The fluid flowing in the converters is water in most cases. One of the problems of using water in exchangers is sedimentation, corrosiveness and the possibility of growth of microorganisms and macro-organisms. It is very important to solve these problems in order to reduce energy consumption, increase productivity and reduce depreciation in facilities. Sediments formed on working surfaces; They increase resistance to heat transfer between two fluids and cause corrosion in systems. In order to increase the productivity and efficiency of the system and to prevent the formation of sediments on the walls of the converters, the surfaces of the facilities and pipelines, as well as to reduce the rate of electrochemical corrosion and general corrosion in the facilities, anti-sediment and anti-corrosion materials should be used. Before that, the formed sediments should be removed without damaging the facilities. | All the functional properties of the product have been carried out by organizations such as Oil Industry Research Institute, Shiraz University and many large industrial consumers such as Continental Plateau Oil, Khuzestan -Dez District Hydropower Plant Repair Company and Behnoosh Iran Company. | Заявка на материалы |
| Anti-Sediment Solution | Anti-sediment materials prevent the sediments from sticking together and make the particles suspended and dispersed in the circulating water so that they can be removed from the system through the water itself. | When water is used as a thermal fluid, the solutes and hardness in the water are separated due to the temperature shock and deposited on the surfaces. These sediments are one of the most important factors of erosion and corrosion in thermal and refrigeration facilities. The presence of sediments, along with the erosion and corrosion of the equipment, cause the heat exchange not to take place and wastes a significant amount of energy and reduces the efficiency of the facilities. The effect of sedimentation on energy loss is a topic that has received more attention today, so that the annual cost of energy loss due to sedimentation is estimated at 45 billion dollars in all countries, which is equivalent to 2.0% of the net production of the whole world | The main chemical compounds that cause deposits in water pipes, boilers, cooling systems, and reverse osmosis water purification devices are: calcium carbonate, calcium sulfate, barium carbonate, barium sulfate, magnesium carbonate, silica, and calcium phosphate. Common anti-sediment agents include formulations of synthetic resins, mostly acrylate bases, polyphosphates (sodium tripolyphosphate), soluble chelating agents (EDTA), and sometimes biocides to control microbial contamination. Antifouling materials with anionic functional groups (phosphate or carboxylate) create electrostatic interactions with metal ions of barium, calcium and magnesium, etc. or with fine particles of insoluble salts of these ions. This interaction is based on three prevention mechanisms: threshold, crystal deformation and dispersion, and the result is preventing the formation of these mineral deposits. The company's products are based on a synthetic terpolymer including acrylamide, maleic anhydride and AMPS. Another grade includes acrylic acid copolymer and AMPS. After synthesis, the mentioned resins are formulated with other components to achieve the desired final properties. | Заявка на материалы |
| Fire Extinguishing Foam | Generally, this product is used to extinguish class B fires (hydrocarbon liquids and polar solvents) | Various products have been developed by companies for extinguishing different types of fires. One of these products is firefighting foams. Foam is a stable mass of small bubbles that is less dense than oil or water and tends to cover a horizontal surface. This mass flows freely over the surface of the igniting liquid and forms a thick, continuous, airless coating that prevents volatile vapors from entering the air.The main component of the company’s product for film formation is animal protein obtained from the hydrolysis of wool, horn or animal protein residues, which forms firefighting foam by formulation with other materials. | The base of these foams consists of two main components, foaming and extinguishing, which act in two opposite directions, and it is difficult to create compatibility between them. For this purpose, types of anionic, cationic and non-ionic fluorine surfactants are used. It should be noted that the type and number of carbon chains are effective on the quenching power. In the protein foam, there was a possibility of sedimentation, and this challenge was solved by the company. This is a powerful extinguishing product that gently covers the fire and prevents the penetration of oxygen and the chain movement of fuel molecules. Due to the presence of water in this foam, the heat decreases during the fire, and due to the complete covering of the surface of the combustible material in it, oxygen is prevented from reaching the fire. The part that plays an essential role in fire extinguishing is the ability to form a resistant film layer with a suitable expansion coefficient. This product is offered in two types: natural base with high degradability in the environment or protein base structure, as well as chemical base.

Anti-foams are generally divided into three categories: oil, polymer and silicone. | The emergence of foam in various industries is one of the factors that will create a negative and downward effect on production efficiency. The production of foam involves many problems and causes adverse effects on the related industry, and that is why the use of anti-foam is necessary. In general, foam occurs in the processes of food processing, chemical production, fermentation, textile industry, adhesive production, printing ink, paint, coating and resin, petrochemical and refinery industries in mixing, filtration, dilution, filling product containers, distillation and reflux. . The occurrence of foam in various industries reduces the efficiency of equipment and imposes high costs. For this reason, appropriate control and interventions are very important to eliminate this phenomenon. In industrial processes, foams cause serious problems. They cause defects in surface coatings and prevent efficient filling of containers and cause overflow of materials inside production tanks in various industries. In addition, the speed of chemical reactions of physical processes related to chemicals also decrease, among which we can mention a sharp drop in the efficiency of crushing processes or a change in the rheological properties of fluids. | This product is generally a chemical additive that is used in various industries such as paint and resin, paper making, alcohol making, etc. These materials are used in a very small amount in the formulation, but in the same small amount (below 1% and usually in the range of 0.1%), they leave a great impact on the final performance of the product. Its final function is very sensitive. Consumers of this product replace commercial products that are currently used in their production line. Therefore, this product must be able to provide not only a good performance in the customer's production line (both prevent the formation and growth of foam and prevent adverse effects such as creating unevenness of the film or stains or creating non-viable colors in the paint), but also be able to simulate the performance of an foreign reference product that has overcome these challenges. This product is available as an oil-in-water emulsion or an oil-in-organic solvent solution. The main components of this formulation are: 1. Hydrophobic agent: This agent here is silicone oil, which is absorbed on the interface of fluid (usually water) and air and makes it unstable. 2. Solid particle: this agent here is usually nano silica. After it is absorbed on the interface along with silicone oil, it destabilizes it by creating defect points on the surface and prevents the formation and growth of bubbles on the one hand, and on the other hand, it destabilizes and destroys the formed bubbles. 3. If the product is in the form of an emulsion, an emulsifier is needed, otherwise a solvent is used.

This product is in the form of polymer granules, which is used as the final layer in a Steel Pipe Coating system and also in cable coating. This coating system is known to be very effective in preventing corrosion in steel pipes | One of the most efficient methods of coating metal pipes is the use of a three-layer polyethylene pipe coating system. These coatings consist of layers of meltbonded epoxy, glue, and high-density polyethylene. In the method of coating metal pipes, we use a system including one layer of EBF, Epoxy Bond Fusion, one layer of intermediate glue and one layer of high density polyethylene as the final layer (Jacket Black). | The formulation of this product includes 4 different components. The main parts of this product include two main components, i.e. polyethylene polymer and black masterbatch (containing 40 weight percent of carbon black). It should be noted that in the final composition of the product, the percentage of soot reaches about 2 weight percent. The melt flow index is suitable for the production of plastic film, and the mechanical and functional properties of the film, such as resistance to cracking caused by environmental stress, are about 5000. | Заявка на материалы |
| Crude Oil Desalting Materials | These materials cause the separation of water from the water/oil emulsion and prevent problems such as corrosion, difficulty in transferring oil, and reducing the quality of oil | The desalination process is one of the most important steps in the operating units in the crude oil processing wells and the first step in the refinery units. The crude oil extracted from the well after the separation of gases and accompanying water contains some water in the form of water-in-oil emulsion, which contains various mineral salts such as sodium, magnesium and calcium chloride. | The function of these materials is such that they cause the thin membrane around the water emulsion droplets to break. In fact, demulsifiers are surface activators and neutralize the emulsifying agents of water. However, excessive injection of these materials causes the production of new emulsion materials and creates many problems in the wastewater treatment process. Therefore, accurate calculations must be done in determining the injection rate of these substances. The emulsions formed are usually not weak and cannot be neutralized by mechanical forces. Therefore, in most cases, demulsifiers must be injected into the system. These substances are insoluble in salt water and highly soluble in oil. For this reason, they can quickly move in the oil phase and reach the surface of the particles, and with this, salt water droplets stick together more easily and form larger particles. The company's product is ethoxylated phenol formaldehyde resin. These parts are important in the quality of the final product: the polymerization of the resin with a certain molecular weight, the distribution of the certain molecular weight and its ethoxylation rate. | Заявка на материалы |
| Synthesis of Various Peroxide Initiators for Polymerization Reactions | They are usually used as initiators in radical polymerization reactions. | Peroxides are a group of organic compounds with a peroxide functional group (ROOR) in which the bond between O-O is broken under the influence of controlled agents and free radicals are formed. Organic peroxides are initiators of polymerization reactions and are highly oxidizing, unstable, dangerous and explosive substances. Due to the complex production technology, polymerization initiators are considered important and strategic raw materials of petrochemical and polymer industries and have a special position in this industry. The technical knowledge of the production of these initiators is often exclusively under the control of industrial and advanced countries of the world. Peroxide compounds should be stored in opaque containers in cool places without vibration. Heat and light accelerate chemical reactions with peroxides and should be avoided. | These initiators are synthesized by the reaction between an organic acid, mineral acid and peroxides. In all stages of temperature control, the flow rate of raw materials, mixing speed, the percentage of raw materials, etc. are essential factors. The storage conditions of these initiators are very difficult and they are mainly kept at negative temperatures (-15°C) and sent to petrochemicals by containers equipped with cooling systems. | Заявка на материалы |
| UPVC Window and Door Profile Stabilizer (Based on Lead) | ٭ UPVC door and window profiles ٭ PVC pipes and fittings ٭ Cable sleevings ٭ Foamed PVC sheets | The structure of PVC makes this composition highly sensitive to temperature and cutting pressure, and as a result, it is easily destroyed. The destruction of PVC causes the release of hydrochloric acid gas, which will cause the catalytic effect of destruction and thus; Degradation proceeds very quickly. This process produces large amounts of HCL gas, which is corrosive and toxic. This is why thermal stabilizers are used. According to the process conditions and formulations, these stabilizers will be different. Most stabilizers contain metal elements that react with HCL and prevent further degradation. | Stabilizer packages include stabilizers, mineral fillers, emollients, lubricants, process aids, and special additives such as flame retardants. Stabilizing packages are used in most products to provide thermal stability and rheology behavior adjustment, and these materials should be changed according to the customer's formulation. One of the sensitive products that have the most stabilizing package components is UPVC door and window profiles. Due to long-term exposure to sunlight, this product must have a suitable environmental resistance. Also, the primary color of the profile should be suitable and in the formulations with high calcium carbonate, proper lubrication is necessary to prevent burns. | Заявка на материалы |
| Anti-Sticking Agent | Used in PBR mills | The manufactured product is a substitute for laurate salt. In the process of styrene polymerization, to increase the mechanical strength of the polymer, polybutadiene is used to create transverse connections and produce HIPS products. Consumable polybutadiene rubber (PBR) is purchased in blocks of 20 to 50 kilos and must be ground and converted into small pieces before being added to the polymerization reactor. Because this material has a high adhesion, the smaller parts produced during grinding quickly stick together and lose their efficiency when the grinding process is applied. To solve this problem, a special type of lauric acid salt is used in the petrochemical industry, which is added to PBR during grinding and prevents the sticking of the milled rubber parts. The presented product has different bases and is prepared without the use of lauric acid. At the global level, the only effective material used in the polybutadiene rubber (PBR) mill is the chemical potassium laurate, which, despite some problems in its use and due to its sensitivity and the possibility of disrupting the polymerization process, the manufacturing companies have not been able to find a replacement for it. This product is prepared without the use of lauric acid compounds, and after many tests, it has replaced the imported material as a new material with the firm approval of the Petrochemical Research Unit | ٭ Anti-sticking agent for use in the production of HIPS (polybutadiene rubber adhesion prevention) ٭ Appearance: yellow to red-brown oily liquid ٭ Ionic Properties: Mainly anionic ٭ Solubility: It dissolves well in water ٭ pH: 9.5 ± 1 ٭ Cloud point > 30°C ٭ Boiling point > 90°C ٭ Density: 1.3 ٭ Storage conditions: Store in a closed place at a temperature of 10 to 45 degrees Celsius and away from flammable materials, heat and flame. ٭ Expiration date: one year after production ٭ Packaging: 60 kg plastic containers | Заявка на материалы |
| Modified Two-Component Mortar Based on Latex | This mortar has technical advantages in sealing concrete resources and tanks, swimming pools, building services and water and sewage channels, as well as economic benefits in construction projects. As a result, it has been introduced as the most suitable alternative to insulation systems such as Qirguni, Izogam and white insulation. | The product is a type of concrete that, as a result of adding a styrene-butadiene emulsion latex dispersed in water, improves some properties, including compressive, tensile and bending resistance. Also, the permeability of concrete against chlorine and salt has been significantly reduced. | This product is a combination of cement base powder reinforced with polymer and acrylic base sealing resin. Among its capabilities, we can mention the ability to seal all concrete and cement tanks and pools with a thickness of 3 to 4 mm and without the need for auxiliary mesh fibers. In addition, the possibility of bearing pressure up to 2 bar is one of the other features of this product. | Заявка на материалы |
| Antistatic Material | This substance is used in the petrochemical industry in the production of expanded polystyrene to increase the surface stability of the produced polymer and prevent sparks and explosions. | The manufactured product is an antistatic material that is used to neutralize electric charges in the production process of expanded polystyrene. The use of antistatic in the drying path of EPS (expanded polystyrene) grains produced before the separating sieves is important from two perspectives: 1. Due to the presence of pentane in the system, there is a possibility of causing an explosion as a result of the electrical discharge of the charged seeds, which causes irreparable damage. 2. The electric charge of the grains disrupts the grain grading by creating larger masses and blocking the openings of the sieves. For this purpose, the antistatic solution is sprayed on the seeds with a spray system. | ٭ Antistatic material for use in the production of EPS (expandable polystyrene) ٭ Appearance: yellow oily liquid with distinct alcoholic smell ٭ Solubility: It dissolves well in water ٭ pH: 1±8.5 ٭ Boiling point: > 70°C ٭ Density: 1 to 1.02 ٭ Storage conditions: Store in a closed place at a temperature of 10 to 30 °C and away from flammable materials, heat and flame | Заявка на материалы |
| Anti-Milkstone Deposits Detergent | The product is used to remove milk stone in washing tanks, pasteurizers, operators and pipelines and fittings in the dairy industry | This product is formulated to be added to alkaline detergents, especially caustic soda, and by having dispersant and surfactant, it increases the washing power and causes the separation of stains and milk stone in dairy factories. | Traditionally, soda is used for CIP (Cleaning In Place) washing, which is unable to separate the milk stone from the surfaces and reduces the work efficiency in the milk powder process. The presence of these sediments increases fuel and energy consumption and causes faster depreciation of equipment. By adding this product to caustic soda, the time interval between two CIP increases and the CIP time decreases, and therefore the milk powder production efficiency increases. Energy consumption is reduced due to the removal of milk powder sediments and the increase of the heat transfer coefficient, and the consumption of acid and water is saved in other stages of CIP. Due to the fact that milk sediments contain proteins and calcium in addition to fat, therefore, special detergents are required that can synergistically break down all these compounds and somehow remove them from the surfaces in a short period of time. | Заявка на материалы |

When this product is applied on metal, with its penetrating power and high adhesion, it buries all corrosions and pleats and reaches the microscopic level of the metal. At this stage after waxing, it permanently protects its underlying surfaces against decay, rust and all corrosive factors. Applying this product on concrete makes the desired surface waxed and protected against moisture, corrosion and penetrating agents in general. | Technical properties of the product: Fam (color) / Black Base / Bitumen Resin type / Polymer Gloss / Semi-glossy Number of components / single component Density / 0.9±0.05 g/cm3 to modify bitumen, polymer compounds such as styrene block copolymers (SBS, SEBS) or polyolefinic compounds such as (APP, etc.) are used to improve rheological properties and improve adhesion. | Заявка на материалы |
| PVD Hard Nitride Coatings on Industrial Parts | These coatings can be applied on different types of sub-layers. These items include: types of extrusion molds, deep drawing, rolling, wire drawing, punching, forging, diecasting and plastic injection, drilling tools, gearing, finger milling, punching, internal threading , plastic cutting, paper and plastic shredding, medical cutting and surgery and cutting of wood, piston ring, gauges, pins and other parts under abrasion can be applied. Among the general properties of this category of coatings, we can mention the increase of hardness, reduction of friction coefficient and surface roughness, very good adhesion to the substrate and improvement of corrosion resistance of the coating | Machining has been the main process of shaping engineering parts throughout history. For each machining process, durable and long-lasting, efficient and reliable tools are needed. Cutting tools are one of the main parts in the machining process. In the competitive environment of the industry, tools should move towards increased life, increased quality and better efficiency, and less need for lubrication. In this regard, there are fundamental challenges: for example, in order to prevent the breakage of a tool and reduce abrasion, it is necessary for the tool to be flexible, while flexibility is the opposite of hardness. Usually, a material is either very hard or has high flexibility, and having these two properties at the same time is a contradictory desire. The solution to this problem is to protect tools made of flexible materials (such as steel) by using hard coatings. As a result, you can have a tool that is resistant to breakage while also taking care of it against abrasion and mild adhesions. One of the methods of applying coatings with high hardness and in nanometer and micrometer thicknesses is the Arc-PVD method. In this method, the voltage generated by the power supply causes an electric arc between the anode and the cathode. The arc current is concentrated on a very small surface of the cathode (target) and creates a very high current density, which causes the cathode to evaporate and turn it into ionized vapor. Ionized steam reacts with gases entering the chamber (oxygen, nitrogen, etc.) and deposits a thin ceramic layer on the surface of the target piece. | Due to the low chemical reactivity of these coatings with the work pieces, the tool is protected against welding and creating a sticky surface. The result of all these effects is that cutting with a coated tool increases the cutting speed and increases the life of the cutting parts. Hard protective coatings are usually nitrides of intermediate metals, which have high hardness, high resistance to abrasion and oxidation. | Заявка на материалы |
| Synthesis of Water-Based Organosiloxane Waterproofing Polymers | These surfaces have special properties such as: self-cleaning, anti-friction, anti-ice and snow, waterproof and anti-corrosion. This product makes surfaces hydrophobic | Coatings and super-hydrophobic surfaces in general are a class of smart coatings that are gaining an important position in the field of technology and industry. These surfaces have very little friction with water and this causes water to flow over them with minimal pressure difference. In addition, the water droplets roll instead of sliding on their surface. The rolling of water droplets on the surface causes the pollution on the surface to be removed from the surface along with them. | A criterion to distinguish between hydrophilic and hydrophobic surfaces is generally the water contact angle (WCA). Accordingly, surfaces with WCA greater than 90° are called hydrophobic and those with WCA greater than 150° are called superhydrophobic. In order for a surface to be able to provide high hydrophobicity, it must: 1. have suitable surface chemistry and in fact very low surface energy 2. have a surface texture with high roughness and on a nano scale. The product under review is the synthesis of an organosiloxane resin emulsifiable in water, which is applied on cement and brick surfaces or on the surface of textiles and protects them from water penetration and wetting. This product is available in different types and in some types it also provides super hydrophobic behavior which makes the surface self-cleaning. | Заявка на материалы |
| Biodiesel on an Industrial Scale | This product is used as a substitute for diesel fuel or as an additive to diesel engines | This product is the result of the esterification reaction of vegetable or animal fats of food waste with methanol in the presence of basic catalyst (KOH). The advantages of biodiesel compared to diesel fuel are: safe transportation, availability, renewablity, higher cetane number (48-75), less sulfur and aromatic content, higher combustion temperature and more natural degradability. With the production of biodiesel from waste oil sources, the costs related to urban wastewater treatment and replacement of the sewage system are greatly reduced. | In this product, an oil refining step is performed before the reaction. The reaction is carried out in a single step at a temperature below 100°C and a pressure of 1 bar, and finally it is converted into two phases of glycerin and biodiesel. Then, after separating the two phases, routine purification operations (filtration, washing and dyeing) are performed. | Заявка на материалы |
| Safe Flammable Materials | This product is used to make fire. | Mankind is facing many problems in the field of lighting fire and lighting coal. In the past, they used oils made from the skin and fat of animals to light the fire, both in industrial use and in recreational use and home gas stoves. With the passage of time and human access to fossil fuels, first crude oil and bitumen and then kerosene, gasoline and petrol replaced oils.These types of fuels cause serious damage to the environment as well as human health due to the creation of greenhouse gases and soot particles resulting from incomplete burning, and they are also part of non-renewable fuels and contain volatile and polluting compounds, which are very dangerous and unsafe.Alcoholic compounds are used in the formulations of the compounds available in the market, such as fire-causing gels and alcohol tablets, which are biologically carcinogenic, and also due to the volatile nature of alcohol, their shelf life is short and they will gradually lose their properties. Also, the cost of their preparation is high and it takes a lot of time to light the coals. Among their other disadvantages, we can mention low efficiency and creating a low flame, and as a result, not lighting the fire well, as well as emitting polluting gases. | The company's product is in three forms: cube, spray and liquid. One of the innovations of this product is its complete safety, so that this product creates fire only by pouring it on wood or charcoal and does not create fire on other surfaces. Its spray form is also non-explosive and does not explode in any way, even in the furnace and oven. | Заявка на материалы |

| Polymer Packing Used in BOP (BLOW OUT PREVENTER) of Oil Wells | To prevent splashing of fluids inside the well | In the drilling of oil wells, it is very important to prevent the fluids inside the well from splashing out. There are flammable, toxic and corrosive fluids with very high pressure inside the oil well, which can be thrown out of the well and cause very harmful accidents. For this reason, a structure called blow out preventer or BOP is installed at the head of the well to prevent this risk. These BOPs are classified into two categories: Ram and Annular. | In the Ram type BOP, an activator must be injected behind the P-seal to maintain its function. This material must be able to be injected into the back of the p-seal in some way and perform a leak stop. This leak stop factor is called plastic packing. This mixture should have several features: 1. It should not be destroyed under the stress caused by friction with the drill bit. 2. It should not change its dimensions and properties when exposed to gases and fluids in the well. 3. Hydrocarbon and water absorption should be very small. 4. It should create low friction with the drill bit. 5. It must be able to inject under temperature and pressure. 6. It should maintain its elastomeric property at the injection site to realize leakage prevention. 7. It should perform properly at high temperature of the well. In order to provide suitable mechanical properties, the company has introduced Kevlar fibers and carbon fibers in the structure. In addition, in order to provide lubrication behavior and low friction, graphite, fluorine, polymer and molybdenum sulfide have been used as fillers. In order to achieve waterproof and oil-proof properties at the same time, fluoroelastomer has been used as the main base. Fluoropolymers have both hydrophobic and oleophobic propertie | Заявка на материалы |

These damages can lead to holes and holes in the part, which completely disrupt the performance of the part. In these cases, efforts will be made as much as possible to repair the damaged part and eliminate the need to replace it. | This product must have many features and in the course of its development, many challenges must be overcome, among which the following can be mentioned: 1. This material must be able to have a high resistance to abrasion and corrosion. 2. The product must have a high hardness. 3. Adhesion of this mixture to the metal substrate should be suitable. 4. It is expected that the coefficient of thermal expansion of this product will be close to that of the underlying metal. 5. If necessary and if it is placed in high friction situations, this product should have a smooth surface as much as possible. 6. The product should be customized for different situations and functions. 7. The product must be machinable. In many cases, the repaired position with this material must be made into the desired shape during the machining process. 8. In some cases, the magnetic behavior of the part is also important, and in such situations, this product should be developed with the desired magnetic property. The product is a two-component product developed mainly based on Novalac epoxy resin. In order to improve its abrasion and corrosion resistance, ceramic particles have been used inside it.

| Heat Transfer Nanofluid | The nanofluid product can be used in a variety of heat exchange systems such as heaters and heat exchangers with water-based fluids, ethylene glycol and oils. | Common heat transfer media usually consist of fluids such as water, ethylene glycol and various oils. These fluids have a low thermal conductivity compared to nanoparticles. For example, the thermal conductivity coefficient of copper at ambient temperature is 700 times the thermal conductivity coefficient of water and 3000 times the thermal conductivity coefficient of engine oil. Therefore, it is possible to improve their performance by adding nanoparticles to conventional thermal fluids without changing the design of mechanical systems. | The obtained product is actually a combination of synthesized nanocarbon with a conventional thermal fluid such as water and ethylene glycol. The addition of nanocarbon will increase the thermal transfer characteristics of the desired fluid, but it will not affect the thermal range of the fluid. The concentration of nanocarbon used is very low and below 5%. Things such as single-walled or multi-walled nanocarbon, size of nanocarbon, morphology, type of functionalization, etc. are conditions that should be optimized for a suitable nanofluid. | Заявка на материалы |

These solutions are mixed with ethylene glycol as an antifreeze additive with a low percentage (5-6 by weight percent) and are produced and marketed as ready to use antifreezers in antifreeze manufacturing companies. | In the structure of the engine (engine body, cylinder head, water pump, etc.), various metals and metal alloys are used, such as iron, steel, copper, brass, and most importantly, aluminum. Therefore, it is necessary to fully protect these metals against all kinds of corrosion mechanisms, such as electrochemical corrosion and cavitation phenomena, galvanic corrosion, etc.In general, in the production of these additives, they are formulated based on the prevention of corrosion of all types of metals such as steel, cast iron, steel, aluminum, copper solder and brass in the engine system. These additives should be such that, in addition to being miscible in water and not reacting, they do not have a negative effect on other properties. The ingredients in the formulation are as follows: 1. Yellow metal compounds (such as copper, brass, etc.) - use of organic compounds such as azoles, benzoates, etc. to prevent the corrosion of these metals 2. Metals such as steel, steel, iron and cast iron - the use of mineral compounds such as phosphates, sodium nitrites and... 3. Aluminum and solder - use of sodium silicate compounds 4. Additives to adjust pH and Adjusting the concentration of the solution in water All these compounds are combined with specific percentages with a suitable pH range and temperature, and finally a viscous solution or a specific pH range is presented as the main product, which becomes antifreeze by combining with 95% ethylene glycol. | Заявка на материалы |
| PVC Paste Stabilizer | Therefore, the additives used should be non-toxic in addition to stabilizing PVC. | Polyvinyl chloride or PVC is one of the most widely used polymers due to its suitable physical and mechanical properties. However, this polymer may be degraded during the process. Therefore, stabilizers should be used as additives in it. These materials prevent the rapid destruction of PVC. | The company's products are based on calcium and zinc and do not contain lead or tin. These products are offered in two grades that have the same structure and differ only in the ratio of calcium and zinc and the type of antioxidant. This difference is related to the use of stabilizer in the production of the final product. The grade with higher transparency and lower thermal stability is used in transparent films and the production of medical equipment. Another grade is used to produce products such as hoses, which are generally thicker and less sensitive to transparency. | Заявка на материалы |

This is an equilibrium reaction and is associated with the release of water, which must be removed from the environment during the process. But there is always some water left in the system. The reaction is carried out under ambient pressure and temperature. The reaction is equilibrium and after reaching a percentage of progress, it is either stopped or greatly slowed down. The most important issue in the purification of these solvents is that these solvents are mostly azeotropic with water, making it difficult to purify them to high purity. | name / Purity (%) / Boiling point (°C) / Application Methyl acetate / 99.5 and 85 / 57 / All kinds of air dry paints, glues and nail polish removers Ethyl acetate / 99 / 77 / The main application of ethyl acetate is in printing and packaging industries.

| Methyl Acetate with a Purity of More than 99% | Methyl acetate solvent with high purity (over 99%) and small water content is widely used in the industry, especially the printing industry, and can be used as a substitute for acetone. This solvent has a vapor pressure and boiling point close to that of acetone. Its solubility constant is also somewhat close to acetone (its polar solubility constant is slightly lower) and can act as a substitute for acetone in many cases. | Methyl acetate is an ester solvent synthesized during the reaction of methanol with acetic acid. This product is produced with a purity below 98.9% in a singlestage condensation known for the presence of acid catalysts, specifically paratoluenesulfonic (p-toluenesulfonic) acid (PTSA). Its production occurs under an equilibrium reaction associated with water removal. But in any case, some water remains in the system. The reaction is carried out under environmental pressure and temperature. The reaction is equilibrium; after reaching a percentage of progress, it is either stopped or slowed down. | Reactive distillation process is a combination of distillation process and chemical reaction, both of which happen simultaneously inside a tower. This combination is very effective for processes where the reaction occurs at the appropriate temperature and pressure for separation. The simultaneous separation of the production products from the reaction causes the inappropriate side products to be removed from the process. As a result, the efficiency of the operation increases. For this reason, the problem of separating substances that have a boiling point close to each other or form an azeotrope together is largely eliminated. The desired reaction can be homogeneous and non-homogeneous catalytic reactions, creating several advantages compared with conventional processes. The company uses this method in product production. In the production of methyl acetate, because the product with methanol makes an azeotropic compound and this compound is 81.3 percent by weight of methyl acetate, and the rest is methanol, all the existing producers in the country are not able to produce higher purity methyl acetate due to the special conditions of this process. The importance of producing methyl acetate with %99 purity is due to breaking this azeotrope in a tower that does both the work of the reactor and the distillation tower. | Заявка на материалы |

| Methanol with a High Purity of 99.5% (USP Grade) and with a High Purity of 99.8% (GC and HPLC Grade) | ٭ USP grade methanol has medical uses in medical diagnostic laboratories. ٭ GC and HPLC grade methanol, as their name suggest, are used as mobile phases in GC and HPLC devices to identify and separate different compounds | The process of purifying chemical compounds, including methanol, is a process in which the degree of purity of the product must reach a value that can be used for its special application. Degrees of purity, in order of increasing degree of purity, are high purity, pharmaceutical grade or USP (abbreviation of United State Pharmacopoeia) and HPLC grade. Of course, there are laboratory grades, dry grades, GC grades, etc., which have a lot of overlap with the above-mentioned three grades of purity. Increasing the degree of purity of some substances up to the USP level and some up to the HPLC level can have technical complications both in the design of the reaction (raw materials and catalyst) and in the design of the process to perform the purification process. Of course, cost considerations will also be an important part in choosing the method and process used for material purification. The level of high purity, USP and HPLC is a certain amount for each substance. For methanol, high purity grades mean purity grade ≥ 99%, USP grade - purity ≥ 99.5% and HPLC grade purity ≥ 99.8. | If the impurities are volatile, fractional distillation or reverse distillation will be required. Due to the relative proximity of the boiling points of water and methanol (the difference is about 35°C) and other impurities, and also to achieve a high degree of purity, the component-by-component distillation method is used. The most important and complex part of this method is the design of the column or distillation tower. The column creates the vertical path through which the vapor must pass in the transfer from the distillation vessel to the refrigerant. During the transfer of steam from the distillation vessel to the top of the column, some of the steam is condensed. If the lower part of this column is kept at a higher temperature than the upper part, the liquid will condense and partially evaporate again while it falls to the bottom of the column. The non-condensed steam along with the steam obtained from the re-evaporation of the condensed liquid rises inside the column and passes through a series of condensation and evaporation. These actions cause the re-distillation of the liquid, so that in each of the stages of the vapor phase that is created, enriches the more volatile component. The condensed material that flows down the column enriches the material with less volatility compared to the steam that is in contact with it in each stage. The longer the column, the higher the purity of the volatile component. | Заявка на материалы |
