Pure Oil Small Oil Refinery Machine

Hydration degumming is the use of phospholipids and otherinsoluble impurities hydrophilic gum, a predetermined amount of hot water or dilute alkali, salt, and phosphoric acidelectrolyte aqueous solution are added under stirring in thehot crude oil, so that one of the water absorption gelaggregated insoluble impurities , then separated.thisprocess uses the warm water of hydration process type, asmall oil refinery in warm water commonly used method.Further, by adding a certain amount of hydrated phosphoricacid, after the reaction, the oil in the non-hydratablephosphatide, converted to hydratable phosphatide. Suchphospholipid content is greatly reduced, can achieve betterresults unglued.crude oil both contain a certain amount of free fatty acids,through refining, and crude oil may be in the majority of thebig free fatty acids, fatty acid sodium salt does not dissolvegenerated in oil, become flocculation substance and sedimentation. Sodium hydroxide and sodium soaps of fattyacids and generated, fast'response, and the resulting sodiumsoap surfactant adsorption and absorption capabilities arestrong, can be a considerable amount of impurities, such asproteins, pigments, phospholipids and substances with hydroxyl also into the sediment, suspended solids and evenfluff soap group may also be carried down, alkali refiningmost significant advantage is that having deacidification,degumming, off solid impurities, the combined effects ofdecoloration.
