摘要
A process for producing a chlorine-free hydrochloric acid low in AOX from crude gases containing hydrogen chloride and organic impurities has been found. The crude gases wer subjected to a thermal treatment at 800. degree. to 1600 in a reducing atmosphere. The hydrochloric acid obtained after absorption of the hydrogen chloride is chlorine-free and contains virtually no organic impurities. The waste gas is also chlorine- free.
