desulfurization (FGD) gypsum, phosphogypsum (PG), and fluoro­ gypsum. FGD gypsum is a by-product of the recovery of sulfur oxides from the flue gases generated at power plants that burn coal. A natural contaminant of coal, sulfur is almost completely converted to sulfur oxide (SOx) when coal is burned. FGD processes result

Approximately 50% of all gypsum used in the manufacture of gypsum board in the United States is FGD gypsum (epa.gov). References Henkels, Paul J., Jr.,2006, Gypsum plasters and wallboards, in Industrial …

byproducts, primarily calcium sulfate (CaSO₄) commonly called gypsum. Gypsum is recyclable or marketable for many industrial uses. The gypsum created by a power plant that is not reused is disposed of in permitted landfills along with scrubber byproducts that are not reusable.

Finally, the gypsum is "washed" using a vacuum filtering system to remove chlorides and salts and additional surface moisture. The removal of these impurities creates a high-quality gypsum that is suitable for use in …

Moreover, FGD gypsum is increasingly used in agriculture as a soil amendment, which can improve soil structure, increase water retention, and provide …

Gypsum from a plant's FGD system can be a lucrative way for coal-fired plants to avoid landfill disposal requirements and recover some plant operation costs. However, utilities must consider some ...

Interest in using gypsum as a management tool to improve crop yields and soil and water quality has recently increased. Abundant supply and availability of flue gas desulfurization (FGD) gypsum, a by-product of scrubbing sulfur from combustion gases at coal-fired power plants, in major agricultural producing regions within the last two …

The feasibility of flue gas desulphurization (FGD) as concrete admixture was studied. A combined concrete admixture of the thermally-treated FGD gypsum and slag powder was explored. The FGD gypsum was roasted at 200 °C for 60 min and then mixed with the slag powder to form FGD gypsum-slag powder combined admixture in which …
