Patent AT-E400350-T1: [Translated] METHOD FOR REMOVAL OF , HCN AND H2S AND OPTIONALLY COS, CS2 AND NH3 FROM A GAS STREAM
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.
