Deacidification
crude oil both contain a certain amount of free fatty acids, through refining, and crude oil may be in the majority of the big
free fatty acids, fatty acid sodium salt does not dissolve generated in oil, become flocculation substance and sedimentation.
Sodium hydroxide and sodium soaps of fatty acids and generated, fast response, and the resulting sodium soap surfactant adsorption
and absorption capabilities are strong, can be a considerable amount of impurities, such as proteins, pigments, phospholipids and
substances with hydroxyl also into the sediment, suspended solids and even fluff soap group may also be carried down, alkali
refining most significant advantage is that having deacidification, degumming, off solid impurities, the combined effects of
decoloration.

Decolorization
In addition to its oil pigment prolapse, but also serve to reduce the phospholipid content, peroxide value, the amount of soap and
the role of the metal ion content containing oil to improve the color, flavor and enhance oxidative stability. The most commonly
used method is activated clay adsorption decolorization, i.e. with clay having a strong selective adsorption of this material,
under certain conditions, in removing oil-soluble dye or with colloidal particles of the pigment dispersion in oil and other
impurities, thereby obtaining improve oil color.
