First Stage of Vegetable Oil Refining Process. Degumming is the first process in the vegetable oil refining which commences with the heating of crude oil. The feedstock is taken into the degumming vessel where the temperature of oil is raised slowly. The main purpose of degumming is to remove the Phospholipids / Gums from the crude vegetable oils. There are generally two different types of phospholipids present in the crude oil

09.01.2018· Degumming process in oil refining plant is to remove gum impurities in crude oil by physical or chemical methods, and it is an oil purification process. After screw pressing and solvent extracting from oilseeds, crude oil mainly contains triglycerides and few non-triglyceride. The non-triglyceride composition including phospholipids, proteins, phlegmatic and sugar would react with triglycerides to form colloid, which is known as gum impurities.
