Introduction to FGD Gypsum. FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers."
Jul 30, 2010· Synthetic gypsum, which is now used in about 30% of drywall, is a byproduct of coal-fired power plants. It is sometimes confused with fly ash—another coal combustion product that’s been in the news recently—but the two have very little in common. Synthetic gypsum is also called flue-gas-desulfurization (FGD) gypsum.
Synthetic gypsum, which is now used in about 30% of drywall, is a by-product of coal-fired power plants and comprises about 95%, by weight, of American Gypsum wallboard. American Gypsum say it is processed almost identically as you would natural gypsum rock.
Byproduct Gypsum : Byproduct gypsum is the ultimate recyclable. It comes from a process used to remove sulfur dioxide from emissions at coal-fired power plants. After the power plant removes fly ash and other impurities from the coal combustion process, the remaining stack emissions are fed through a limestone slurry which removes sulfur dioxide.
A detailed design and cost study has been carried out into the consequences of adding f.g.d. to a typical new 2000 MW coal fired power station in the U.K. The process chosen for this study was the Wellman-Lord process which is the only regenerative process which could be considered as commercially proven.
The Pomorzany power plant in Poland also started up a similar sized unit in 2003 and that plant removes both sulfur and nitrogen oxides. Both plants are reported to be operating successfully. [19] [20] However, the accelerator design principles and manufacturing quality need further improvement for continuous operation in industrial conditions.
Coal-fired power plants that discharge flue gas desulfurization (FGD) wastewater will be as gypsum, which is a main component of wallboard gypsum. The chloride becomes a dissolved solid and the chloride concentration continually increases until Design Chloride Equilibrium : ppm .

Dec 10, 2016· Gypsum is traditionally mined, which makes it really expensive. But coal-fired power-plant cleaning processes have created a new variety of gypsum: flue-gas desulfurization (FGD) gypsum. Since it’s technically a waste product, FGD gypsum is a lot cheaper than mined gypsum (which is expensive due to shipping costs).

3. FGD Gypsum is Created at Power Plants. FGD gypsum is formed when fossil-fueled power plants utilize flue gas desulfurization systems to remove sulfur dioxide from gas pollutants. Using a process referred to as ‘scrubbing,’ gas pollutants are fed through calcium carbonate to eliminate impurities and environmental concerns.
