Acid gas injection eliminates sulfur recovery expense

Sour natural gas containing sulfur in the form of hydrogen sulfide (H2S) presents a double cost to producers. First, the gas has to be sweetened with a solvent, and second, most of the H2S has to be converted to sulfur. Both processes are expensive. Acid gas reinjection eliminates sulfur compounds and carbon dioxide (CO2) emissions into the atmosphere. This compression and injection process has been rapidly developed and adopted in Western Canada for handling acid gas streams from sour gas sweetening facilities.
