Simultaneous Removal of SO2 and NO from Flue Gas Using Ozone

摘要

The objective of this work was to study the effect of some operating condition on the simultaneous removal of NO and SO_2 from simulated flue gas in the lab-scale agitated bubbling reactor. The experimental results showed that NO removal efficiency increased with the increase in the molar ratio of O_3/NO, while removal efficiency of SO_2 decreased. When absorption liquid changed from distilled water to Na_2CO_3 solution, it is observed that removal efficiencies of NO and SO_2 increase with the increase in the concentration of Na_2CO_3 solution. At 0.08 mol/L of Na_2CO_3 solution, the removal efficiencies of SO_2 and NO are 100% and 93%, respectively.
