Each technology is examined for their ability to filter, wash and dry the gypsum to meet the moisture content for salable FGD gypsum as compared with natural gypsum. The paper continues with an analysis of the utilities required for each technology including electricity and water usage and the ability to reuse water in the process.
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.
For more than 20 years, Gypsum Association members have successfully and safely developed and deployed technologies to use flue gas desulfurization (FGD) gypsum as a key ingredient in the manufacture of gypsum board (AKA wallboard or drywall).
