ABSTRACT:
Hydrogen sulfide is removed from natural gas by contacting the natural gas with a scrubber oil that absorbs the hydrogen sulfide. The natural gas typically contains some water, or water can be added, and the resulting mixture is used to form a water-in-scrubber oil emulsion. Sulfur dioxide added to the water-in-oil emulsion reacts with the hydrogen sulfide present in the emulsion.
