When the first (ammonium sulfate) stream is substantially composed of ammonium sulfate, the decomposition product comprises ammonium bisulfate, ammonium pyrosulfate, or a mixture of the two compounds. As reported by Halstead (J. Appl. Chem., 1970, 20:129-132), the thermal decomposition of ammonium sulfate produces ammonia and ammonium bisulfate. The ammonium bisulfate can then undergo dehydration to form ammonium pyrosulfate. However, the practice of the invention is not limited by the relative amounts of ammonium bisulfate and ammonium pyrosulfate in the decomposition product.
