FGD gypsum also known as synthetic gypsum is manufactured through the process of flue gas desulfurization. Flue gas desulfurization is a technology used to eliminate sulfur dioxide SO 2 from exhaust flue gases of fossil-fuel power plants. The process keeps the air clean and provides sustainable and ecologically sound source of pure gypsum.
the primary byproduct is calcium sulfate, commonly known as synthetic gypsum, or flue gas desulfurization FGD gypsum. This synthetic gypsum is used in the manufacturing of wallboard and cement, and as a soil amendment in agricultural and construction applications Duke Energy, 2017.
The cost effective benefits of yielding a flue gas desulfurization FGD sludge predominantly composed of CaSO42H2O, have been previ-ously established. The recovery of this material as FGD by-product gypsum has been demonstrated abroad. Recently U.S. wallboard manufacturers have recognized the viability of this recovery practice.
The Flue-Gas Desulfurization FGD process utilizes a set of technologies to remove sulfur dioxide SO 2 from the flue gas emissions of coal-fired power plants.FGD systems were developed as a response to the exhaust flue gases from fossil fuel-burning plants, principally coal-burning, that posed both an environmental and human health hazard.
