“…The objective of this work was to develop a process to simultaneously remove both SO 2 and H 2 S. A thorough literature search revealed very few approaches for achieving this goal. − This approach has the potential to eliminate the partial oxidation step of H 2 S to SO 2 required for regular Claus unit operations to form elemental sulfur.…”

Tail-gas streams from refinery processes such as Claus units often contain and emit SO 2 and H 2 S at levels exceeding permissible emission limits, which are currently set at 10 ppm H 2 S and 250 ppm SO 2 (U.S.). Gas compositions vary widely depending on the application, with some containing high levels of SO 2 , H 2 S, 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 a two-stage process is presented. The new process would compete with currently established technologies such as amine scrubbers or Cansolv units (property
