Degumming
Heating crude oil to around 70–90 °C for acid or water degumming, ahead of gum separation.
Recommended type
Standard Gasketed Plate Heat Exchanger
Phosphatide content drives this stage, which is why it matters most on soybean oil; other crudes still pass through it. Hydrated gums are sticky and raise the fouling rate, so where the crude runs high in phosphatides a wider channel buys a longer run between cleans.
