    8.4 Ammonium Sulfate 8.4.1 General1-2 Ammonium sulfate (NH42SO4) 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


    Background Report Ap42 Section 6

    Synthetic ammonium sulfate is produced by combining anhydrous ammonia and sulfuric acid in a reactor. Coke oven byproduct ammonium sulfate is produced by reacting the ammonia recovered from coke oven offgas with sulfuric acid.
