Abstract
A process for removing metals in a petroleum oil material. The process comprises causing the petroleum oil material to react with a removing agent which comprises a phosphoric acid ester. A microwave irradiation environment was created during the reaction to provide the required energy essential for separating such contaminations from the oil chemical network. The process of the invention is applied at ambient pressure and low temperature compared to the conventional metal removal processes. The process of the invention can be readily scaled up and integrated into an industrial facility.

A process for removing metals in a petroleum oil material, comprising the steps of:
- (a) mixing the petroleum oil material with a removing agent, which comprises a phosphoric acid ester;
- and an aqueous phase, and subjecting the reaction mixture to stirring for a first period of time, at a temperature which is lower than the boiling point of the removing agent using microwaves;
- (b) adding a first mixture of solvents including water to the reaction mixture, and subjecting the aqueous reaction mixture to stirring for a second period of time, at a temperature which is less than about 90° C.;
- (c) allowing the aqueous reaction mixture to stand for a third period of time, thereby obtaining an oil phase comprising a treated oil and one or more phases including an aqueous phase;
- and
- (d) subjecting the aqueous reaction mixture to separation thereby yielding the treated oil.
