Simultaneous Removal of SO2 and NO2 by Wet Scrubbing Using Aqueous Limestone Slurry

摘要：

The simultaneous removal of SO2/NO2 by limestone slurry was studied in a gas-liquid bubbling reactor. Experiments were carried out to find the effect of various operating parameters such as inlet concentration of SO2 and NO2, reaction temperature, O2 content in the flue gas and additive on the SO2 and NO2 removal efficiencies. SO2 removal efficiency decreased with inlet NO2 concentration, reaction temperature and O2 content in the flue gas. Inlet SO2 concentration had a favorable effect on NO2 absorption while reaction temperature and O2 content in the flue gas had an inhibition effect on it. And additives such as MgSO4 and Na2SO4 could promote the removal of SO2 and NO2.
