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 desulfurization technology in the desulfurization process, several semi-dry desulphurization...

Based on the demand of sintering/pelleting flue gas ultra-low emission, a semi-dry method using a spray dryer absorber (SDA) combined with O-3 oxidation was proposed for simultaneous removal of SO2 and NO. Effects of O-3 injection site, O-3/NO molar ratio, and spray tower temperature on the removal efficiencies were investigated. It was revealed th...

Aiming at SO2 and NOx in industrial flue gas, the simultaneous removal of SO2 and NOx was conducted using red mud as absorbent with O-3 oxidation. The effects of different factors on the desulfurization and denitration efficiency were investigated. The results show that the increase of oxidation temperature is not conducive to the absorption of NOx...

Simultaneous removal of NOx and SO2 by MgO combined with O-3 oxidation was studied. The effects of the O-3/NO molar ratio, oxidation temperature, and oxidation residence time on N2O5 decomposition and O-3 consumption distributions were systematically illustrated, which is of great significance for improving NOx removal efficiency and reducing O-3 c...

NO oxidation using O-3 is studied, including the product composition under different conditions and the oxidation selectivity in complex flue gas. The O-3/NO molar ratio determines the type of oxidation products. N2O5 is generated when the O-3/NO molar ratio is greater than 1, and the N2O5 yield increases with the improvement of the O-3/NO molar ra...
