Abstract

501,208. Gas purifying materials; sulphur ; ammonium salts. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Aug. 25, 1937, No. 23339. Drawings to Specification. [Class 55 (ii)] [Also in Group III] Ammonia and hydrogen sulphide are removed 'from gases by scrubbing first with an ammonium sulphite - bisulphite solution, removing substantial amounts of hydrogen sulphide, then with an alkaline liquid containing heavy metal compounds forming sulphides which are afterwards regenerated by oxidizing gases; and finally with an ammonium sulphite-bisulphite solution, which is used for the first and final stages in either order and then added to the second stage liquid. Thiosulphate solution branched off from the cycle of the second stage liquid may be boiled to obtain sulphate and sulphur which may be used in preparing sulphur dioxide for making the sulphite-bisulphite solution ; or this may be derived from sulphur formed during the oxidation of the alkaline washing liquid, or from combustion of the hydrogen sulphide in waste gases from treatment of gas liquor. In an example, coke oven gas is first scrubbed with ammonium polysulphide to remove cyanogen and the ammonium thiocyanate formed may be caused to react with an excess of sulphuric, nitric, phosphoric, or hydrochloric acid, the said solution being added to concentrated thiosulphate solution from the second stage washer before boiling to obtain sulphate and sulphur. Or this solution may be acidified with sulphur dioxide and heated to 140‹ C. in a pressure-tight vessel:
