摘要
WorleyParsons创新性二氧化硫还原工艺可有效地从二氧化硫气体中回收硫,能够处理矿石沸腾炉、冶炼和燃煤电厂排放气以减少硫排放量。该新工艺是对几种成熟工艺的创新性组合:CH4与硫蒸气反应生成CS2, CS2随后催化水解生成H2S,H2S与SO2进行Claus反应生成硫。主要优点是较低的燃料消耗、较少的排放量、较好的产品硫质量和较高的操作稳定性。
WorleyParsons innovative SO2 reduction process efficiently recovers sulphur from SO2 streams. Effluent gases from ore roasters and smehers and coal-fired power plants can be treated to reduce sulphur emissions. This exciting new process is an innovative combination of well-established processes of reaction of CH4 and sulphur vapor to produce CS2, followed by catalytic hydrolysis of CS2 to HES, and Claus reaction of HES and SO2 to sulphur. Key advantages are lower fuel consumption, reduced emissions, better product sulphur quality and better operational stability.
