Investigation on Mercury Reemission from Limestone-Gypsum Wet Flue Gas Desulfurization Slurry
Secondary atmospheric pollutions may result from wet flue gas desulfurization (WFGD) systems caused by the reduction of Hg(2+) to Hg(0) and lead to a damping of the cobenefit mercury removal efficiency by WFGD systems. The experiment on Hg(0) reemission from limestone-gypsum WFGD slurry was carried out by changing the operating conditions such as the pH, temperature, Cl(-) concentrations, and o...
متن کاملParameters Affecting Efficiency of Flue Gas Desulfurization System Using Wet Limestone Method
Efficiency of Flue Gas Desulfurization System (FGD) is affected by numerous technical parameters like: proper fuel preparation, quantity and quality of fuel, combustion conditions in furnace chamber, quality of flue gas corresponding to the operating conditions of FGD system, design quantity and quality of flue gas at the inlet of FGD system, design quantity and quality of used sorbent, design ...
متن کاملMicrobial communities associated with wet flue gas desulfurization systems
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. Despi...
متن کاملFlue gas desulfurization
Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...
متن کاملMicrostructure contradistinction for indirect/direct desulfurization product layer of limestone particle in coal-fired flue gas
The micro morphology of limestone sorbent is a key for improving the SO2 removal efficiency in the coal-fired power plant. The tube furnace system was built for imitating the indirect desulfurization reaction in traditional boiler atmosphere (65%N2, 15%CO2, 4.7%O2, 15%H2O, 0.3%SO2) and the direct desulfurization reaction in oxygen-fired atmosphere (80%CO2, 4.7%O2, 15%H2O, 0.3%SO2). The reacted ...
