Oxidation, reemission and mass distribution of mercury in bituminous coal-fired power plants with SCR, CS-ESP and wet FGD

► Mercury speciation variations in flue gas at the inlet and outlet of various air pollution control devices. ► Effect of temperature, flue gas flow rate, flue gas components (HCl, SOx and NOx) on mercury oxidation. ► Mercury oxidation in SCR systems, reemission of Hg0 in a wet FGD and factors related to it. ► Statistical analysis of the factors promoting co-beneficial control of mercury in coal-fired power plants. ► Comparative mass distribution of mercury in SCR + CS-ESP + wet FGD and CS-ESP + wet FGD configuration and their implication.
