Abstract:
1. A system for improving oil recovery from a liquid source of oil, comprising: a membrane contactor system in contact with a liquid source of oil and at least one collection fluid; and a heater connected to the at least one collection fluid; wherein the membrane contactor system has one or more membranes each having a first and a second surface, wherein at least one of the first and second surfaces coalesce one or more oils from the liquid source of oil allowing the coalesce oil to be collected on an opposite surface of the membrane by at least one collection fluid, wherein the at least one collection fluid is selected from non-polar fluid, hexane, benzene, toluene, diethyl ether, chloroform, dichloromethane, and ethyl acetate, and wherein the temperature increase of the collection fluid enhances the oil recovery at the membrane contactors from the liquid source of oils.
