Synthetic Gypsum an overview | ScienceDirect Topics

Using “synthetic” or recycled gypsum board can significantly reduce several of these impacts. Synthetic gypsum accounts for approximately 20 percent of U.S. raw gypsum use and is made from the byproducts of manufacturing and energy-generating processes, primarily from desulfurization of coal-power-plant exhaust gases.

Synthetic Gypsum | BuildingGreen

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.

Flue-gas desulfurization Wikipedia

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime
