EFFECT OF NO AND NO2 ON ELEMENTAL MERCURY CONCENTRATION IN COMBUSTION FLUE GAS
IntroductionGaseous mercury is largely classified into elemental mercury (Hg°) and oxidized mercury (Hg+2) according to its oxidation form. The level of these mercury species in flue gas varies depending on the kind of fuels used and on the temperature history of flue gas.Elemental mercury does not dissolve in water 1. However, if the elemental mercury is oxidized, it can be removed by WFGD (wet flue gas desulfurization), because the oxidized mercury is water soluble.Elemental mercury in flue gas can be oxidized by homogeneous gas phase reaction under the presence of halogen species or acid gases, or by heterogeneous reaction with solid such as fly ash containing catalytic ingredient on it and specially treated activated carbon for oxidation 2. In this study, the effects of NO and NO2, which are representative acid gases in combustion flue gas, on the elemental mercury concentration in a combustion flue gas were analyzed.
