OIL-WATER SEPARATOR, OIL-WATER SEPARATING SYSTEM, OIL-WATER SEPARATING METHOD, AND WATER REUSING METHOD USING OIL-WATER SEPARATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an oil-water separator requiring no complicated multistage process or special equipment, having good handleability and operation management property, and allowing high-level oil-water separation of heated oil-containing water to reduce heat loss; an oil-water separating system using the oil-water separator; an oil-water separating method; and a water reusing method.;SOLUTION: In an in-situ recovery method for producing bitumen from oil sand, bitumen is taken out from a heated bitumen mixture fluid collected from the underground, and oil contained in the heated oil-containing water separated from the mixture fluid is removed by the oil-water separator. The oil-water separator includes: a vessel 15e into which the oil-containing water 20B is introduced; an immersion filtration film 61 built in the vessel 15e to perform filtration while being immersed in the heated oil-containing water; and a bubble generation means 16 supplying bubbles 53 toward the filtration film 61.;COPYRIGHT: (C)2011,JPO&INPIT
