With the vigorous development of China's iron and steel industry and the introduction of ultra-low emission policies,the emission of pollutants such as SO2 and NOx has received unprecedented attention.Considering the increase of the proportion of semi-dry desulfur-ization technology in the desulfurization process,several semi-dry desulphurization tech-nologies such as flue gas circulating fluidized bed(CFB),dense flow absorber(DFA)and spray drying absorption(SDA)are briefly summarized.Moreover,a method for simultaneous treat-ment of SO2 and NOx in sintering/pelletizing flue gas by O3 oxidation combined with semi-dry method is introduced.Meantime,the effects of key parameters such as O3/NO molar ratio,CaSO3,SO2,reaction temperature,Ca/(S+2N)molar ratio,droplet size and approach to adiabatic saturation temperature(AAST)on denitrification and desulfurization are ana-lyzed.Furthermore,the reaction mechanism of denitrification and desulfurization is further elucidated.Finally,the advantages and development prospects of the new technology are proposed.
