The mercury removal from the flue gas discharged from a 100 MW coal-fired power plant in China by non-carbon sorbents CuCl2 impregnated alumina and zeolite were experimentally investigated in this paper. When the sorbent were added into, the mercury speciation in flue gas across ESP was directly sampled and analyzed using EPA 30 B standard method. The effect of injection rate was studied. The mercury balances measured on-site were between 77.1%—111.5%, and the results of mercury balance after correction sug...
