Fuerstar - Several Methods of Refining Crude Oil

When extracting oil, the extracted crude oil needs to be refined, so do you know how to refine the crude oil?

1. Mechanical method: mechanical method is mainly through precipitation, filtration and some centrifugal oil frying separation, mechanical method of separation through the separator, mechanical method is mainly used to remove some mechanical impurities and colloidal impurities suspended in the oil.

2. Chemical methods: chemical methods mainly include oil refining, acid, alkali, some can be acid treatment through esterification and oxidation, mainly used to remove pigments and colloidal impurities, alkali refining effect for alkali treatment, mainly to remove free fatty acids, for decolorization treatment.

3. Logistics chemical method: mainly including splashing, decolorization, distillation of water distillation, etc., hydration is mainly used to remove phospholipids, decolorization and decolorization of pigments. The role of water distillation mainly includes acid refining, alkali refining, lipidation, oxidation, etc. Acid refining is the acid treatment, mainly to remove pigments, colloidal impurities, alkali refining is alkali treatment, mainly to remove free fatty acids, oxidation is mainly used for decolorization. It is used to remove odor substances and free fatty acids. After treatment by refining equipment, the gross oil can reach the national standard, and the water content in the oil. Impurities, acid value, peroxide value are in line with national quality standards, not easy to spoil and deteriorate, easy to store, crystal clear color, light flavor, cooking does not produce a lot of oil smoke, maintain high quality flavor.
