Solvent oil consists of two processes: cutting distillates and refining. There are usually three methods to cut the fraction: directly from the atmospheric column; cut the corresponding light fraction into a suitable narrow fraction; and fractionate the catalytic reforming raffinate. It is usually necessary to refine various solvent oil fractions. Improve color, stability, remove corrosive substances, reduce toxicity. The common refining methods are alkali washing, clay refining and hydrofining. Main uses: solvent oil is one of the five major types of petroleum products. Solvent oil is widely used. A large amount of paint solvent oil (commonly known as paint solvent oil), followed by edible oil, printing ink, leather, pesticides, pesticides, rubber, cosmetics, spices, medicine, electronic components and other solvent oils. At present, there are about 400-500 kinds of solvents on the market, of which solvent oils (hydrocarbon solvents, benzene compounds) account for about half.
