1. A method for degumming and/or refining oil containing impurities, comprising the steps of:
- providing a flow-through, hydrodynamic cavitation device having a flow path there through;
pumping oil containing impurities into the flow path of the flow-through, hydrodynamic cavitation device at a pre-determined pump pressure;
mixing a degumming agent with the oil containing impurities;
generating cavitational features in the oil containing impurities within the flow-through, hydrodynamic cavitation device such that the impurities are transferred from an oil phase to a water phase; and
separating the oil phase from the water phase.

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.
