The integrated removal technology of mulitiple pollutants from coal-fired flue gas uses deacidification solvent to react with and then remove the pollutants such as SO_2 and HCl in the flue gas. In order to find out the best deacidification agent
an integrated removal experiment bench based on ceramic catalytic filter tube is built up. The deacidification activities of three deacidification agents such as Na2 CO_3
NaHCO_3 and Ca(OH)_2 are studied. The results show that the removal efficiency of Ca(OH)_2 to SO_2 and HCl increases with the Ca/S molar ratio. When the Ca/S molar ratio is 3
the desulfurization efficiency reaches 85% and the HCl removal efficiency reaches 91%. In addition
the removal efficiencyies of Na2 CO_3 and NaHCO_3 to SO_2 and HCl increase with the Na/S molar ratio. When the Na/S molar ratio is 3
the desulfurization efficiency and the HCl removal efficiency of Na2 CO_3 reach 90% and 97%
respectively. The desulfurization efficiency and the HCl removal efficiency of NaHCO_3 reach 91% and 98%
