Brief introduction:
After preheating, add a certain amount of hot water in the crude oil for degumming. Then add a certain amount of alkali liquor in the degummed oil for alkali refining reaction, and centrifuge out soap stock and oil. After removing soapstock out, the oil begin water washing, centrifuging, and vacuum drying by heating. After dehydration, oil go into the bleaching pot for bleaching, and fitering clay or active carbon. Then after heat exchanger, the decolored oil enters into the deodorization pot. After deodorization, fitering and cooling, the oil enters into the finished oil tank.
1.Degumming Section: Some impurity, such as Phospholipid, gum, and protein, can be dissolved  into oil when there is no water, but once there is water in oil, these impurity can be dissolved into water. So, in degumming section, we use the hot water to wash crude oil for two-three times to remove these impurity.
2.Neutralizing Section: Crude oil contains much free fatty acid, which is harmful for health. Free fatty acid can have the reaction with caustic soda, during the reaction, it can be saponified and becomes soapstock, then small soapstock pellets will sink and  becomes sediment and be pumped out. After neutralizing, most of the free fatty acid will be removed out.
3.Decoloriztion Section: Most of the crude oil has deep color because of the pigments, such as carotene, xanthophyll, etc. We use bleaching earth to remove pigments, because bleaching earth has strong adsorption capacity. Then pump oil into plate filter to  remove bleaching earth, then pigment also will be removed out along with bleaching earth, then oil will be clean and transparent.
4. Deodorizing Section: Pure oil has no smell, but different crude oil has their special smell because of some volatile matters, for example the oxide for ketones, aldehydes, hydrocarbons. In deodorizing section, we deliver steam into oil continuously, and make  sure steam and oil can fully contacted under high temperature and pressure, then volatile matters can be removed out along with the steam.
