Abstract: The invention relates to a process for the removal of SO2, HCN and H2S and optionally one or more compounds from the group of COS, CS2 and NH3 from a first gas stream, which process comprises the steps of: (a) removing SO2 from the first gas stream by contacting the first gas stream in a hydrogenation zone with a hydrogenation catalyst in the presence of hydrogen to obtain a second gas stream; (b) removing HCN and optionally COS and/or CS2 from the second gas stream obtained in step (a) by contacting the second gas stream in a hydrolysis zone with a hydrolysis catalyst in the presence of water to obtain a third gas stream; (c) removing NH3 from the third gas stream by contacting the third gas stream in a NH3-removal zone with an aqueous acidic washing liquid to obtain an ammonium-comprising aqueous stream and a fourth gas stream; (d) removing H2S from the fourth gas stream by contacting the fourth gas stream in a H2S-removal zone with an aqueous alkaline washing liquid to obtain a H2S-depleted gas stream and a hydrogensulphide-comprising aqueous stream; (e) contacting the hydrogensulphide-comprising aqueous stream obtained in step (d) with sulphide-oxidizing bacteria in the presence of oxygen in an oxidation reactor to obtain a sulphur slurry and a regenerated aqueous alkaline washing liquid; (f) separating at least part of the sulphur slurry obtained in step (e) from the regenerated aqueous alkaline washing liquid and; (g) recycling regenerated aqueous alkaline washing liquid obtained in step (e) to the H2S-removal zone in step (d).

Abstract: Disclosed is a process for the removal of sulfur from a gas stream containing sulfur dioxide, hydrogen cyanide and hydrogen sulfide. The process includes a hydrogenation step, a hydrolysis step, an ammonia removal step and a hydrogen sulfide removal step. An aqueous alkaline washing liquid is used in the hydrogen sulfide removal step and with the spent sulfide containing washing liquid being regenerated using an oxidation bioreactor that utilizes sulfide oxidizing bacteria such as autotropic aerobic cultures of Thiobacillus and Thiomicrospira.
