We investigated simultaneous absorption of SO2 and NO X in a packed column with ammonia, and found that SO2 and NO X could promote absorption with each other in the process of simultaneous removal SO2 and NO X . The removal efficiency of SO2 and NO X was, respectively, about 98% and 70.9% at pH 5.5, temperature 323.15 K, SO2 concentration 1,800×10−6, NO X concentration 400×10−6 and $${{m_{NO_2 } } \mathord{\left/ {\vphantom {{m_{NO_2 } } {m_{NO} }}} \right. \kern-\nulldelimiterspace} {m_{NO} }}$$ in our experimental system. The experimental results also show that the formation of sulfite oxidized by reacting with dissolved NO2 and the molar ratio of sulfite to total sulfur is more than 0.8 in the solution. Accordingly, the energy consumption for sulfite oxidation would be greatly reduced in the process of simultaneous desulfurization and denitrification with ammonia.
