摘要: The mechanism of SO2 and NO removal by chemical absorption enhanced with electromigration in corona discharge has been studied. The experiments were performed to investigate the effect of discharge voltage, gas flow rate, and inlet concentrations on the removal efficiency of SO2 and NO in an electromigration-enhanced chemical absorption reactor. The results showed that electromigration can enhance the chemical absorption rate of SO2 and NO. Removal efficiency of SO2 and NO increased with the increase of discharge voltage; the efficiency increments of SO2 and NO may reach up to 23.6% and 24.2% at 21 kV, respectively. Under experimental conditions, the increase of gas flow rate and SO2/NO inlet concentrations had no significant effect on SO2 removal efficiency because of the strong electron affinity and solubility, while the NO removal efficiency was significantly reduced with the increase in these parameters.
