Abstract

In order to achieve effective removal of NO2 by sodium sulfite solution with a high oxygen concentration, an additive was explored in this study. Flue gas was oxidized by ozone and was then absorbed by sodium sulfite solution adding ethanol into with a high oxygen concentration. Research showed that sodium sulfite solution, with the addition of ethanol, was an effective absorbent in high oxygen concentrations. Influencing factors such as the type of additive, added ethanol concentration, absorption temperature, absorption product, and enrichment of ion (NO2- and NO3-), were investigated during the absorption process of the NO2 by sodium sulfite solution. The optimal additive was ethanol in the removal of NO2 by sodium sulfite solution. In regard to the absorption product, NO2- and NO3- were reaction products, which decreased absorption efficiency of NO2. Furthermore, increase of ethanol concentration in sodium sulfite solution could counteract adverse effects of ion during the absorption of the NO2.
