ABSTRACT:
This specification discloses a method of producing petroleum from a petroleum-bearing formation. A hot aqueous fluid is generated in a hot aqueous fluid generator that is fired with a sulfur-containing fuel and the hot aqueous fluid is injected into the petroleum-bearing formation and petroleum is produced therefrom. The firing of the hot aqueous fluid generator with the sulfur-containing fuel produces a flue gas which contains sulfur oxides. The flue gas is treated with alkaline water in a system comprised of a venturi scrubber vessel and a trayed emission scrubber vessel to scrub the sulfur oxides from the flue gas and the scrubber flue gas is discharged from the trayed emission scrubbers.
