Refining process generally refers to the process of processing crude oil into various fuels (gasoline, kerosene, diesel), lubricants, paraffin, asphalt and other petroleum products or petrochemical raw materials (such as n-alkanes, benzene, toluene, xylene, etc.). The general process of petroleum refining is to first cut crude oil into various fractions with different boiling ranges, and then remove non ideal components and harmful impurities from these fractions according to product specifications, or undergo chemical conversion to form the required components, and then process them into products.
The main process of petroleum refining can be roughly divided into five categories:
Separation process - electric desalination, atmospheric and vacuum distillation
Conversion process - catalytic cracking, hydrocracking, residue hydroprocessing, delayed coking, visbreaking, etc
Refining and upgrading processes - hydrogenation refining, catalytic reforming, medium pressure hydrogenation upgrading, S-Zorb, etc
Refinery gas processing processes - alkylation, etherification, benzene and ethylene alkylation, etc
