Brief introduction of crude oil refinery plant
Oil refinery plant refers to a series of refining processes that can remove phospholipids, FFA, pigment, off-flavor and other impurities in the oil Edible oil refinery or vegetable oil refinery is essential to ensure removal of gums, waxes, phosphatides
Oil refinery plant usually includes the following sections: Degumming, Neutralization, Bleaching, Dewaxing and Deodorization. The process of removing these impurities after oil extraction section is called oil refining. The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage.
Main process of crude oil refinery plant
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.Decoloraztion 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
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.
