• Ammonium sulfate

    B) Synthetic production of ammonium sulfate out of ammonia gas and sulfuric acid. Synthetically, ammonium sulfate is obtained by reacting gaseous ammonia and sulfuric acid. In this appliion, too, the processing of „waste sulfuric acid" from production processes is more the reason for building ammonium sulfate plants than the global demand for ammonium sulfate.
