Description

Sulfur is recovered by converting H2S to Elemental Sulfur. Sulfur recovery takes place in a series of two steps: Claus Process and SCOT Process. In the Modified Claus Process, partial combustion of H2S takes place to generate SO2 that is reacted with the remaining H2S to recover Sulfur as Elemental Sulfur. The Modified Claus Process, once-through burner operation, works only with acid gases that contain more than 50% H2S by volume. In the process, Hydrogen in H2S is converted to H2O. The second stage, the SCOT Process, functions as a Tail Gas clean-up operation to remove the Sulfur compounds produced in the side reactions of the Claus Process, i.e., Carbonyl Sulfide (COS) and Carbon Disulfide (CS2).
