Abstract

Ammonium carbonate and sulphate are produced in a process for obtaining pure nitrogen from the products of combustion, with slight excess of air of coke oven gas, "lighting gas," poor gas or gases of similar composition. The excess of oxygen is removed by treatment with hydrogen at elevated temperature and the carbon dioxide is absorbed, preferably in ammonia solution, the resulting carbonate being converted into ammonium sulphate. The p combustion gases after being used for heating the hydrogen retorts in the process described in Specification 232,184, [Class 1 (i), Chemical processes &c.], may be used in the process above described.
