Tail-gas streams from refinery processes Such as Claus units often contain and emit SO2 and H2S at levels exceeding permissible emission limits, which are Currently set at 10 ppm H2S and 250 ppm SO2 (U.S.). Gas compositions vary widely depending on the application, with some containing high levels of SO2, H2S, and moisture. This publication describes the simultaneous removal of these sulfur-containing contaminants utilizing a regenerable catalytic sorbent. A simplified process with the potential to reduce a four-stage process to it two-stage process is presented. The new process would compete with currently established technologies Such as amine Scrubbers or Cansolv units (property of Cansolv Technologies Inc., Montreal, Quebec, Canada H2M 2N9).
