Abstract

Procedure for the removal of ammonia hydrogen sulfide and hydrocyanic acid from gases, especially from coke oven gas, in which the hydrogen sulfide and the hydrocyanic acid are extracted by washing with an alkaline solution, and the hydrogen sulfide, by gasification with air, is oxidized in elemental sulfur, while the ammonia is washed, being extracted with an inorganic acid, heating and burning the resulting ammonium salt and leading the formed acid anhydride back to the washing medium circuit, characterized in that the solution, which must be removed from the washing of sulfhydric acid, which contains sulfur compounds and cyanic compounds, together with the ammonia washing salt solution, with the addition of a heating medium, burns, in which the materials containing ammonia and cyanic products are transformed into carbonic acid water vapor, and nitrogen and why it is used as combustion air for the medium d e heating the exhaust air containing ammonia from the oxidizers of the hydrogen sulfide wash.
