The French Petroleum Institute has introduced a regenerative stackgas sulfur scrubbing system intended for application on US power plants. SO/sub 2/ is removed from the stack gas in a scrubber using ammonia in a water solution as the reagent. Scrubber output contains ammonium sulfite, bisulfite, and sulfate. In the second stage of the process, the scrubber liquor is decomposed back to ammonia, sulfur dioxide, and water. Most of the SO/sub 2/ is converted to H/sub 2/S. The mixture is then sent to a fairly conventional Claus process tower in which the H/sub 2/S and SO/sub 2/ react to form molten sulfur. Ammonia from the tower is recycled back to the first stage.
