Abstract
A method for degumming and/or refining crude oil containing impurities involving mixing the crude oil with degumming agents, i.e., water or acid, and subjecting the mixture to flow-through, hydrodynamic cavitation processing. The cavitational processing transfers impurities in the crude oil to a water phase for easier separation. The water phase may be separated from the oil phase by commonly available separation methods.

A method for degumming and/or refining crude oil containing impurities, comprising the steps of:
- providing a flow-through, hydrodynamic cavitation device having a flow path there through;
- mixing the crude oil with a degumming agent to form mixed fluid having an oil phase and a water phase, the degumming agent consisting essentially of water in an amount not to exceed 3% by volume of the crude oil containing impurities;
