We provide different services related to the refinery industry to our customers
Designing, building, and operating a 30,000 BPD mini refinery involves maximizing the conversion of crude oil into high-value products like gasoline and diesel using advanced UOP technology. Key components include units for processing gas, propane, butane, various grades of gasoline, diesel, kerosene, and atmospheric gas oil. The refinery’s processes include distillation and further refining through units like the Naphtha Hydrotreater, Platformer, Fluid Catalytic Cracker (FCCU), and Diesel Hydrotreater, ensuring high efficiency and minimal waste. Support systems include gas plants, fuel gas treating units, Merox units, and facilities for handling sulfur and sour water stripping.

White spirit solvents are hydrocarbon compounds that are produced from cutting kerosene. These materials have aromatic and linear hydrocarbon compounds. These compounds cause to have special fragrant and properties. Based on the percent of aromatic compounds, these materials split into two categories of high & low aromatic. White spirit is colorless and a mixture of 7 to 12 aliphatic and cyclic aliphatic hydrocarbons with a very low solubility in water and an odor threshold between 0.5 to 5 mg/m3.
White spirits are mainly used as extraction solvents, diluents, detergents, carriers of additives and raw materials in many industries such as paint-resin, varnish, adhesive, thinner, wire, waxes and polishes. This material due to its special properties is used for cleaning oils from the surface of metals, greases, carbon etc.
These materials are divided into two categories as Aliphatic, and Aromatic (Benzene, toluene, xylene, etc.).
The uses of solvent 404 are as same as solvent 406.
Solvent 406 is divided into two categories such as Aliphatic, and Aromatic (Benzene, toluene, xylene, etc.). In general, these solvents are extracted from crude oil. These solvents can be used in different fields. For instance, linear paraffin has a low viscosity, while branched paraffin has high viscosity and good low-temperature properties. The combination of these solvents with normal viscosity and low temperature provides us normal temperature.
The uses of solvent 406
1. Producing paints and polishes
2. Cleaning the grease from the surface of metals
3. Producing wood antibacterial material
4. Used in preparing bitumen and production of car tires 5. Cleaning solution for industrial equipment and machines.
The conversion of heavy hydrocarbons to light hydrocarbons is so important due to the less economical value of heavy hydrocarbon. In addition to the less economical value of heavy hydrocarbons, there are some problems in their transformation. One of the reasons for the less economical value of heavy hydrocarbons is the difficulty of manufacturing and using in energy production process. These products, which are often used in less valuable fields such as bitumen and wax, can be converted into lighter products with higher value by processing and breaking large hydrocarbon chains. A large number of production methods of light hydrocarbons from heavy petroleum compounds are based on chemical procedures using catalysts and upper temperature that cause to increase the final prices of manufacturing of lighter products.
Hence development of alternative methods in these processes to reduce energy consumption can pave the way for the development of the production process of lighter petroleum compounds than heavy petroleum compounds with higher economical value. In this regard, cold plasma can effectively play a role in breaking down heavy petroleum compounds and converting them into valuable light hydrocarbons. Cold plasma can be a correct option for using in chemical processes because of its innate nature (an ionized medium with high energy level). Providing an ionized environment with energetic ions that can be a starter of many chemical reactions, including cracking, which can be used as another choice in common methods of refining process. These are so useful in many refineries of the whole world.
Thinners are volatile chemical liquids that are used in diluting paints. These liquids can improve color properties. These materials have a crucial role in color properties, and the time of drying. A right selection of thinner impacts viscosity, cutting properties, separability, drying time, and other properties.
Thinners can be used in cleaning tools and equipment. In order to decrease the viscosity of thinners, these materials are combined with paints to use in paint applicators. Another use of thinner is that it prevents paint from drying after the door is opened.
Lubricants are kinds of materials which are used for reducing friction and exhaustion of dynamic metal parts in contact with one another. Accordingly, a subtle layer of lubricant which is called the viscosity of the lubricant is generated between the parts of machines. Each lubricant consists of a basic substance to which several additives are added. This substance can be mineral (with petroleum source) or synthetic (such as polyolefin, polyesters, and polyethylene glycols). Mineral bases are usually vacuuming distillation products and asphalt residues that have been subjected to solvent extraction, waxing, and refining.
These materials are useful to make sure of correct movement of parts of a machine. The primary role of these industrial substances is to reduce the friction of surfaces of machines, and durability and enhance their longevity. Since we know that friction produces heat, lubricants cause to transferring from the surface of machines and also helps in cooling process. Due to this, this group of substances is also called heat transfer fluids. Moreover, these substances sometimes reduce electrical resistance.
In addition, these substances protect the machines from corroding and rusting during use. Industrial lubricants, oil, and greases can be made of organic or synthetic substances. Most organic lubricants are produced from the refining of petrochemicals, whereas synthetic types of chemicals are made in several reaction stages and the presence of some additives. In general, these materials are available in three forms as liquid, semi-liquid and solid. Engine, turbine, and gear oils are kinds of liquid lubricants.
Gas oil or diesel fuel (French: Gazole) is used as fuel in diesel engines and thermal installations. Its range of hydrocarbon is between C14-C20 and even C25 with a boiling point range of 385-250°C. Gas oil mainly consists of three groups of paraffinic, naphthenic and aromatic with minimum flash point 54°C and maximum pour point of 0°C. Its density is 15.6°C which equals to 820-860 kg / m3. Cetane number is the most important feature that it should be more than 50 so that engine can work easily and silently.
