Characterizing synthetic gypsum for wallboard

Synthetic gypsum produced by wet flue gas desulfurization (FGD) systems on coal-fired power plants is commonly used in the manufacture of wallboard. The FGD process is used to control the sulfur dioxide emissions which would result in acid rain if not controlled. This practice has long benefited the environment by recycling the FGD gypsum byproduct, which is becoming available in increasingFGD gypsum issues (Journal Article) | OSTI.GOV,Synthetic gypsum produced by wet flue gas desulfurization (FGD) systems on coal-fired power plants is commonly used in the manufacture of wallboard. This practice has long benefited the environment by recycling the FGD gypsum byproduct, which is becoming available in increasing quantities, decreasing the need to landfill this material, and increasing the sustainable design of the wallboard product.Gypsum wallboard in the USA - Global Gypsum,American Gypsum: With over 50 years producing gypsum wallboard and other gypsum products, American Gypsum is the fifth-largest wallboard manufacturer in the US with a capacity of 308.6MM 2 /yr. It is owned by Eagle Materials, which also has substantial US cement and concrete assets. American Gypsum has four wallboard plants, three in the southern and central states of Colorado (Gypsum Plant), Oklahoma (Duke Plant) and New Mexico (Albuquerque Plant) and one in South Carolina (Georgetown Plant,Synthetic Gypsum | Green | American Gypsum,The process of making American Gypsum's Synthetic Gypsum (FGD Gypsum) at our Georgetown, SC facility starts at our partner power plants, where SO2 gas (sulfur dioxide) is passed through limestone that is sprayed in the air pollution control scrubber stack. The resulting sludge is then subjected to forced air oxidation to produce Calcium Sulfate (Gypsum), which is washed and inspected to ensure all ofCOMPARISON OF GYPSUM DEWATERING TECHNOLOGIES AT,emissions including conventional wet and dry scrubbing technologies.

Resource Recovery from Flue Gas Desulfurization Systems

A wallboard manufacturer will consider utilizing FGD gypsum when its transport costs are less than the haul costs for mined gypsum. Figure 4 illustrates the cost-distance re-lationship between transporting natural and by-product gypsum. To determine the economic justification for by-product recovery, compare the natural gypsum mine and power plant distances to the calcining plant and calculate theO & M Feature: FGD Gypsum Issues | Power Engineering,At the beginning of 2006, the capacity of operating wallboard plants in the United States was about 37.6 billion square feet per year.2 At present, synthetic gypsum from FGD systems supplies about,COMPARISON OF GYPSUM DEWATERING TECHNOLOGIES AT FLUE,emissions including conventional wet and dry scrubbing technologies.
