  • Design of lime/limestone flue gas desulfurization systems ...

    The double alkali/gupsum method of flue gas desulfurization (FGD) was developed to reduce scaling and plugging problems associated with direct lime (CaO) or limestone (CaCO3) systems. One of the first large-scale installations of this process to control SO2 emissions and produce gypsum (CaSO4) was put in operation in 1973 at the Showa Denko plant in Chiba, Japan.

  • Microbial communities associated with wet flue gas ...

    Flue gas desulfurization (FGD) systems are employed to remove SO x gasses that are produced by the combustion of coal for electric power generation, and consequently limit acid rain associated with these activities. Wet FGDs represent a physicochemically extreme environment due to the high operating temperatures and total dissolved solids (TDS) of fluids in the interior of the FGD units.

  • Limestone Industry - University of Kentucky

    Two mines along the Ohio River in north-central Kentucky (Outer Bluegrass Region) are producing stone from the Camp Nelson Limestone for the manufacture of low-magnesium and high-calcium limes. The limes are used for flue-gas desulfurization at coal-fired power plants, and for steel-furnace flux, chemical manufacture, and water treatment.

  • Testing of sodium thiosulfate as an oxidation inhibitor in ...

    A total of four limestone runs were made on the 10-MW spray tower system from April 10 through May 30, 1981, including two base case runs without thiosulfate (Runs SST 102 and SST 101) and two runs with thiosulfate addition (Run SST 106 and SST 112).
