Abstract

A process for the combined degumming and neutralization of an oil containing phosphatides and FFA, the process comprising: dosing an aqueous degumming reactant into the oil to form a mixture; introducing the mixture into a first set of flow-through hydrodynamic cavitation reactors to form at the exit of the first set of flow-through hydrodynamic cavitation reactors a mixture; dosing, at the exit of the first set of flow-through hydrodynamic cavitation reactors an aqueous caustic solution into the oil to form a mixture of aqueous caustic dispersed into the oil; introducing the mixture of an aqueous caustic dispersed into the oil into a second set of flow-through hydrodynamic cavitation reactors to form a mixture of oil containing hydrated phosphatides and neutralized FFA (soaps); and separating the mixture of oil containing hydrated phosphatides and soaps to obtain an oil phase and an aqueous phase.
