200T physical rice bran crude oil refinery plant

Oil refinery plant, 200T physical rice bran crude oil refinery plant. Physical refining of oil means distillation deacidification, according to the significantly different characteristics of volatility of triglycerides and free fatty acids (under vacuum) at high vacuum (residual pressure 600 Pa or less) and high temperature (240 ~ 260 ℃) carried out the principle of steam distillation, to reach the purpose of removing free fatty acids and other volatile substances. In the distillation deacidification, but also accompanied desolventizing (in terms of oil extraction), deodorization, detoxification (rice bran oil in a number of cyclic hydrocarbon organic chlorine and other toxic substances) and the combined effect of partially discolored.

     Physical oil refining process consists of two parts, namely the pre-treatment and distillation deacidification of crude oil. Pretreatment including impurities removal of crude oil(referring to mechanical impurities, such as cake slag, sand and grass clippings, etc.), degumming (including phospholipids and other adhesive substances, etc.), and bleaching three processes. By preprocessing, make crude oil become pretreatment oil to comply with process conditions of distilled deacidification, which is a prerequisite for physical refining, if pretreatment is not good, it can cause the distillation and deacidification cannot be taken as normal, or cannot get the qualified refined oil. Distillation deacidification including heating, cooling, distillation, and fatty acid recycling processes. Physical refining process is as follows:

     The main equipment in physical refining has detrasher, filter, degumming tank, bleaching tank, oil heat exchange tanks, oil heating tanks, distilling deacidification tank, wax fatty acid condenser and vacuum devices.
