    Lime Limestone Wet Scrubbing System For Flue Gas

    PROCESS After fly ash removal, the flue gas seen in Figure 1 is bubbled through the scrubber, and the slurry is added from above.The lime or limestone reacts with the SO 2 in the flue gas to create insoluble calcium sulfite CaSO 3 as in the equations below. Limestone CaCO 3 s SO 2 g CaSO 3 s CO 2 g Lime CaOH 2 s SO 2 ...

  • Model of the Wet Limestone Flue Gas Desulfurization

    Model Of The Wet Limestone Flue Gas Desulfurization

    May 19, 2001 A detailed process model of the wet limestone flue gas desulfurization system has been presented. This model can be used to calculate indispensable parameters for estimating costs and next to minimize capital and operating costs. The process model describes most important stage of SO2 removal running in an absorber and a holding tank. It includes absorption of sulfur dioxide, oxidation

    Us5630991a Limestonebased Wet Flue Gas Desulfurization

    The limestone dissolution rate for limestone-containing slurries used in wet flue gas desulfurization WFGD systems is enhanced by the addition of ammonium ions. The ammonium ions may be obtained by incorporating into the limestone-containing slurry gaseous or aqueous ammonia andor a water-soluble ammonium salt, such as ammonium sulfate, ammonium chloride, or ammonium carbonate.

  • Wet Flue Gas Desulfurization with LimeLimestone Slurry

    Wet Flue Gas Desulfurization With Limelimestone Slurry

    In wet flue gas desulphurisation, open spray tower absorbers have prevailed which are divided into two principal zones. These are the absorption zone exposed to the flue gas and the absorber sump, in which the limestone slurry is trapped and collected. To prevent deposits in the absorber sump, the slurry is suspended by means of mixing mechanisms.

  • Calcium Bisulfite Oxidation Rate in the Wet Limestone

    Calcium Bisulfite Oxidation Rate In The Wet Limestone

    Apr 24, 1999 In this paper oxidation of calcium bisulfite in aqueous solutions was studied, in connection with the limestonegypsum flue gas desulfurization process. Experimental measurements of the oxidation rate were carried out in a laboratory scale stirred reactor with continuous feeding of both gas and liquid phase. A calcium bisulfite clear solution was used as liquid phase, and pure oxygen or ...

    Limestonegypsum Fgd Wet Desulphurization

    1. Introduction of Flue-gas Desulfurization Flue-gas desulfurization FGD is a set of technologies used to remove sulfur dioxide SO 2 from exhaust flue gases of fossil-fuel power plants, steel company etc, and from the emissions of other sulfur oxide emitting processes. Limestone-gypsum desulfurization process is one of the most widely used ...
