METHOD FOR CONTROLLING CORROSION IN THERMAL VAPOR INJECTION GASES

摘要

METHOD FOR CONTROLLING CORROSIONIN THERMAL VAPOR INJECTION GASESABSTRACT OF THE DISCLOSUREAn improvement in the method for producing highpressure thermal vapor streams from combustion gases forinjection into subterranean oil producing formations tostimulate the production of viscous minerals is described.The improvement involves controlling corrosion in suchthermal vapor gases by injecting water near the flame in thecombustion zone and injecting ammonia into a vapor producingvessel to contact the combustion gases exiting the combus-tion chamber.
