Crude oil refinery plant, is aslo called 15T vegetable oil refinery equipment crude oil refinery plant. It has several processes, such as, degumming, deacidification, bleaching, deodorization and witerization, etc.
1,Degumming: It means using physical, chemical, or physical and chemical ways to remove phospholipid. If the phospholipid content is high. When the oil is heated, it will take foam, smoke, peculiar smell, and phospholipids appear burnt brown color at high temperature. Degumming is based on the principle that phospholipid and portion of the protein oil-soluble in the waste water state, but not oil-soluble after form a hydrate with water, hot water or steam is added to crude oil, heat oil and stirred at a temperature of 50 ℃, then rested stratification, separating the aqueous phase, it can remove phospholipids and some protein.
2, Deacidification: FFA affects the stability and taste of oil, so can remove free fatty acid by adding alkali for neutralization, called deacidification, also called alkali refining.
3, Bleaching: The crude oil contains chlorophyll, carotenoids and other pigments, chlorophyll is a photosensitive agent, which can affect oil stability, and other pigments affect the oil appearance, can be removed by absorption aids.
4, Deodorization: The oil contains some peculiar smell items, mainly from the oil oxidation. It is removed by distillation and adding citric acid to prevent oxidation.
5, Dewaxing/winterization: The wax is from husk of sunflower seed husk, which can affect the quality of oil. It adopts the method that cooling the oil by refrigeration unit and separating wax from oil by oil filter press.
