MARKETABLE AMMONIUM SULFATE FERTILIZER AND FINE

from FGD-gypsum. Ammonium sulfate is a valuable nutrient source for both nitrogen and sulfur for growing plants. There is an increasing demand for sulfur in the sulfate form as a plant nutrient because of decreased sulfur compounds in atmospheric deposition. More stringent regulations to reduce sulfur dioxide emissions by the year 2000 (from 2.5 lbs SO2/10 6 Btu to 1.2 lbs) suggest a growing

Ammonium sulfate Wikipedia

Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas. The heat of reaction evaporates all water present in the system, forming a powdery salt. Approximately 6000M tons were produced in 1981. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O).
