Abstract (en)

[origin: WO2006106289A1] Fuel gas, for example coke oven gas, is treated to remove hydrogen sulfide and ammonia impurities in absorption columns (12) and (18). The absorbent is regenerated in a stripping column (32). A gas stream comprising hydrogen sulfide and ammonia passes from the stripping column to the same combustion stage or furnace (48) of a Claus plant (44). The combustion is conducted under conditions that eliminate essentially all the ammonia. The combustion is supported by a gas stream containing at least 40% by volume of oxygen. Residual amounts of sulfur dioxide and sulfur in the tail gas from the Claus plant (44) are reduced catalytically in a reactor (73) and the resulting gas recycled to the absorption column (12).
