Abstract
Ammonium sulphate preparation by mixing an aqueous solution of a double salt of calcium sulphate and ammonium sulphate with an aqueous solution of ammonium carbonate is characterized in that the ammonium carbonate solution is prepared by treating a solution of ammonium sulphate with ammonia and carbon dioxide in concentration insufficient to cause a separation of ammonium sulphate during carbonation but sufficient to lead to such separation during the reaction with the double salt. The double salt is preferably prepared from a mixture of calcium and ammonium sulphates in water in such proportions that the ammonium sulphate solution remaining after precipitation of double salt, is suitable for the preparation of the ammonium carbonate solution. The calcium carbonate co-precipitated with the ammonium sulphate can be separated by entraining the carbonate in the flowing stream of the reaction mixture while the sulphate settles out.
