8.4 Ammonium Sulfate 8.4.1 General1-2 Ammonium sulfate ([NH4]2SO4) is commonly used as a fertilizer. In 1991, U. S. facilities produced about 2.7 million megagrams (Mg) (3 million tons) of ammonium sulfate in about 35 plants. Production rates at these plants range from 1.8 to 360 Mg (2 to 400 tons) per year. 8.4.2 Process Description1
