What does petrochemical production do?

Refers to the field of the chemical industry in which petroleum is used as a raw material for the production of chemicals The scope of petrochemicals The variety and scope of chemicals produced from petroleum and natural gas is extremely large. Petrochemical raw materials are mainly from the petroleum refining process produces a variety of petroleum fractions and refinery gas, as well as oilfield gas, natural gas and so on. Petroleum fractions (mainly light oil) through hydrocarbon cracking, cracking gas separation can be produced ethylene, propylene, butadiene and other olefins and benzene, toluene, xylene and other aromatics, aromatics can also come from petroleum light fractions of catalytic reforming. Petroleum light distillate and natural gas by steam reforming, heavy oil by partial oxidation can produce syngas, and then produce ammonia, synthetic methanol and so on. From olefins, various alcohols, ketones, aldehydes, acids and epoxy compounds can be produced. With the development of science and technology, the above olefins, aromatic hydrocarbons can be processed to produce polymer products including synthetic resins, synthetic rubber, synthetic fibers and a series of products, such as surfactants and other fine chemicals, so the scope of petrochemicals has been expanded to the polymer chemical industry and most of the fields of fine chemicals. Petrochemical production, generally combined with petroleum refining or natural gas processing, to provide each other with raw materials, by-products or semi-finished products, in order to improve economic efficiency (see petrochemical complex).
