The process for conversion of FGD gypsum to ammonium sulfate and calcium carbonate by the reaction with ammonium carbonate is by a unique combination of countercurrent flows with internal recycle of liquids to maximize the purity of reaction products while minimizing the reaction time.
Gypsum has many other uses, too. In fact, it is used as a filler ingredient in many foods. The average person eats about 28 pounds of gypsum in a lifetime. When gypsum rock is crushed and the water removed, it can be used to make plaster of paris, commonly used in industry.Ground gypsum is also used as a soil conditioner. Chemically, gypsum rock is calcium sulfate with two molecules of water.ational Gypsum also uses another form of calcium sulfate called byproduct gypsum. Byproduct gypsum is produced when power companies scrub their coal-fired emissions to remove sulfur dioxide. The resulting byproduct is calcium sulfate.
