Chat OnlineFGD 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.
