A treatment method for hydrogen sulfide, ammonia and organic compounds containing gases

摘要

Removal of H2S (and also NH3, HCN, org. cpds. such as benzene) from coking plant gases by washing the precooled, compressed gases with a solvent contg. As which catalyses reaction between NH3 and H2S to form ammonium polythionate, and then oxidising this to S, using another catalyst (e.g. cpds. of as, Sb, or Sn).
