  • Mercury in gypsum produced from flue gas desulfurization

     · Abstract. Wet flue gas desulfurization (FGD) technologies used to remove sulfur dioxide (SO 2) from combustion gases can be effective in capturing oxidized mercury (Hg). Depending on the FGD process a large portion of this Hg may be incorporated into the FGD slurry and its solid byproducts including synthetic gypsum a material commonly used in

  • Stackless power plant with flue gas desulfurization

    When the 230-MW Volklingen power plant entered service in August 1982 it became the first power plant in Europe to desulfurize 100 percent of the flue gas without bypass. The FGD system forms an integral part of the cooling tower and the flue gas is discharged through the tower. There is no stack.
