Abstract Information :
CuCl2?MF was a cost?efficient and highly efficient sorbent for Hg removal from flue gas in coal-fired units. In this study, the Hg0 adsorption and oxidation performance of CuCl2?MF with different conditions were studied at a 1000MW commercial scaled coal-fired power plant. Under the optimal conditions, the total removal efficiency of Hg and the Hg recovery rate reached 98.72% and 52.76% using CuCl2?MF injection combined with the existing pollutant control device. The magnetosphere particle size of 45?m?75?m exhibited the highest mercury removal capacity. Additionally, the final mercury emission concentration was 0.334?g/m3 and the corresponding relative mercury removal efficiency was 89.81%. The results of this study proved that elemental mercury removal by CuCl2?MF was also suitable for large-scale coal-fired units with a high Hg removal efficiency even in the low concentrations of mercury, which provided a reference for the practical application of this technology in other units in the future and supplied valuable experience for other mercury removal technologies.
