The ammonia, hydrogen cyanide, and hydrogen sulfide scrubbed out of crude coke oven gases are decomposed and combusted, and sulfur is recovered therefrom in a Claus process, while using preheated air and effecting the decomposition and oxidation at temperatures varying through 100.degree. C. at most, and keeping the temperature level of the entire process above 100.degree. C. and allowing the residual gases to cool below this temperature only after the separation of sulfur, and controlling the air supply to maintain the ratio of H.sub.2 S and SO.sub.2 in the process gases above 2.
