Abstract

266,397. Skoglund, J. V. Sept. 23, 1925. Sulphuric acid.-The nitrous gases in chamber processes for the manufacture of sulphuric acid are recovered by treating them first with sulphuric acid whereby the nitrogen trioxide present is absorbed, then with water or dilute acid to decompose the nitrogen peroxide and finally with acid in the usual Gay Lussac tower. In the plant shown in the Figure, the nitrous gases issuing from the last of the three chambers 13, 14, 15 enter a small preliminary Gay Lussac tower 19 and they are then treated with water in a scrubber 20, the dilute acid formed being re-circulated. The gases finally pass to the usual Gay Lussac tower 23. Instead of using packed towers, the latter may be empty, the acid in this case being sprayed. After being treated with water, the gases must be given time to oxidize to the trioxide stage; this is preferably effected in the Gay Lussac tower itself to avoid reformation of nitrogen peroxide.
