A complete oil refining plant include water washing and alkali refining, dephosphorization degumming, continuous decoloration, continuous deodorization, fractionation and dewaxing workshop
Crude oil→water washing and alkali refining→ dephosphorization degumming→ continuous decoloration→continuous deodorization→to fractionation and dewaxing workshop
1>Degumming：To remove the gum impurities, and prepare for the subsequent refining processes.
2>Deacidfying：To remove the free fatty acid in the crude oil.
3>Decoloring: To remove the pigment in the crude oil by adding active clay, so that can improve the oil quality.
4>Deodorizing：To remove the odor in the oil, so that can improve the flavor, stability, color and quality of the oil.
5>Dewaxing: To renmove the wax in the oil and improve the quality of the oil.
