Abstract
Treatment procedure, for example of coke oven gases, in which hydrogen sulfide is removed from the compressed crude gas coming from a precooler by washing with a solvent containing arsenic and the absorbed sulfur is recovered in an oxidizing apparatus by introduction of oxidation air in the form of elemental sulfur, characterized in that the raw gas containing ammonia, hydrogen sulfide and organic compounds, including benzene, is washed with the solvent without heating or cooling, and with the arsenic contained in it As a catalyst, ammonium polythionates are formed from H2S and NH3, after which, with the addition of another catalyst, the sulfur is oxidized from the ammonium polythionates contained in the solvent.
