Abstract

A mixture is made of nitre cake, sodium sulphate, ammonium sulphate, and water under such conditions that a quantity of anhydrous sodium sulphate is separated, and after the removal of the sodium sulphate, the liquor is used for absorbing ammonia from gases. When used for treating Mond gas, the solution is diluted before the absorption of ammonia and then concentrated again. When treating coke-oven gas or coal distillation gas, this dilution and evaporation may be unnecessary. The absorption of ammonia with the subsequent evaporation causes the separation of sodium-ammonium sulphate, which is removed, and a further evaporation causes the separation of ammonium sulphate, the double salt being used with more nitre cake for repeating the process. When dilution and evaporation are not employed, the absorption of ammonia causes the separation of ammonium sulphate, the mother liquor being used with more nitre cake for repeating the process.ALSO:A mixture is made of sodium sulphate, ammonium sulphate, and nitro cake under such conditions that a quantity of anhydrous sodium sulphate separates, and, after the removal of this sodium sulphate, the liquor is diluted and used for absorbing ammonia from Mond gas and then concentrated again, when sodium ammonium sulphate separates, and may be used with more nitre cake for repeating the process.
