| Abstract | 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 consumption in practical application. When the O-3/NO molar ratio was greater than 1.0, the highest N2O5 yield was achieved at 90 degrees C. The NOx removal efficiency reached 96.5% at an O-3/NO molar ratio of 1.8. The oxidation temperature increased from 90 to 130 degrees C, resulting in the decrease of N2O5 yield, the improvement of O-3-ICC (O-3 invalid cycle consumption) caused by N2O5 decomposition, and the decrease of NOx removal efficiency from 96.5 to 76%. Besides, the effects of pH, SO2 concentration, and MgSO3 addition on NOx removal efficiency were also investigated. The results showed that the removal efficiency of NO(x )decreased with the increase of SO2 concentration, while MgSO3 addition into MgO slurry could promote the absorption of NO2 due to the reaction between NO2 and SO32-. |
