Refining process of eLDpt soybean oil refining

Crude oil → Degumming section → Decolorizing section → Deodorization section → Filter → End product oil

*** Degumming section: under 60-70°C,it occurs acid-base neutralization reaction with sodium hydroxide ,After stirring by reduction box,it can decrease the acid value in oil and separate the impurity ,phospholipid which will enter into soap stock.The oil can be refined further.

*** Decolorizing section:it removes water from oil by vacuum.The bleaching earth is breathed into bleaching pot ,after stirring,filtrated by filter and change the color of the oil.

*** Deodorization setion: The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, and next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C) and then enters the deodorization tower. The upper layer of combined deodorization tower is the packing structure which is mainly used to remove the odor producing components such as free fatty acid (FFA);the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero.
