Synthetic gypsum production

FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum

    The vast majority of the synthetic gypsum used by the industry is a by-product of the process used to remove pollutants from the exhaust created by the burning of fossil fuels for power generation. Nearly 100% of the fiber used in the production of gypsum board face and back paper comes from newsprint and postconsumer waste materials

    In 2004, the estimated U.S. production of crude gypsum was 18.0 million tons. Synthetic gypsum is mainly produced as a byproduct in flue gas desulfurization (FGD) systems. Calcined gypsum is produced domestically from crude gypsum by heating selenite. In the United States, gypsum is primarily used to manufacture wallboard and plaster for

    Jul 30, 2010 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.
