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 Description1Web

• Magnesium sulfate (Epsom Salts) is soluble but calcium sulfate (gypsum) isn't (Rule C). These rules are also helpful in determining the compatibility of fertiliser salts in solution, by considering the solubility of any potential reaction products. For example: • Ammonium sulfate and calcium nitrate are soluble (Rule A).Web

The plant consumes coal at a rate of 0.96 pounds per kwh and the sulfur content of the coal is about 3%. Based on a load factor of 65% for 300 days per year of operation, the plant produces 200,000 tons gypsum per year. Ammonia gas - Assuming 98% recovery, one ton of gypsum could produce 0.752 tons of ammonium sulfate.Web

In this process, a portion of the sludge treated in the digesters is continuously withdrawn and transferred to a thin film evaporator (TFE) unit, where the ammonia is stripped through a biogas stream. The ammonia-rich biogas is treated with a sulfuric acid/water solution in a reactive absorption unit, with production of ammonium sulphate.Web
