Production Of Elemental Sulfur From SO2 (RSR)

WorleyParsons innovative SO2 reduction process efficiently recovers sulfur from SO2 streams. Effluent gases from ore roasters and smelters and coal-fired power plants can be treated to reduce sulfur emissions. This exciting new process is an innovative combination of well-established processes of reaction of CH4 and sulfur vapor to produce CS2, followed by catalytic hydrolysis of CS2 to H2S, and Claus reaction of H2S and SO2 to sulfur. Key advantages are lower fuel consumption, reduced emissions, better product sulfur quality and better operational stability. The Production of elemental sulfur from SO2 is being called Rameshni SO2 Reduction (RSR) and it is patent pending.
