Chemical Degumming AOCS
Chemical degumming involves the liberation of PA from its salts with an acid that is stronger than PA itself. The degumming acid is either phosphoric acid, which forms a precipitate with Ca and Mg, or citric acid, which forms a complex of Ca and Mg.
Chemical Degumming - AOCS
For oils containing relatively low amounts of NHP (e.g. sunflower oil) this process can lead to degummed oil with a lower residual phosphorus content (5 to 30 ppm) than water degumming. The acid degummed oil is then dry degummed and physically refined.

Dry or wet acid degumming are not always sufficient to reduce gums to Value required in the oil prior to the combined deodorization and distillationProcess. Thus, we have
Edible oil refining process systems | Alfa Laval
Edible oil refining process systems. Refining crude oil into edible oil requires deep process knowledge攆rom degumming, neutralization and dewaxing through to bleaching, deodorizing and GE and 3-MCPD mitigation. Edible oil producers worldwide rely on Alfa Laval know-how to remove impurities and volatile components and optimize refining processes.

Degumming - an overview | ScienceDirect Topics
The degumming process combines the acid degumming step with the bleaching process, thus eliminating the water addition and centrifugation of the gums. A 75 to 85% phosphoric acid is added at a rate of 500 to 10,000 ppm weight percent to the oil at 80 to 100 C.
Degumming Process Oil Refinery
Degumming process is part of vegetable oil refinery mainly to remove gums from crude edible oils like soyabean oil. Degumming Process Equipments and Plant are made by us. Degumming Process Equipments and Plant are made by us.
Advances in Treatment of Vegetable Oil Refining Wastes
In physical refining, the crude oil is degummed and bleached and then steam stripped to remove FFA, odor, and VOCs all in one step. This replaces chemical reaction mode using an alkali (caustic soda) in chemical refining. A physical pretreatment is used to achieve low phospholipid content by degumming and using bleaching earth.
