Effect of gas composition on nitric oxide removal from simulated flue gas with DBD-NPC method

A new method for nitric oxide(NO)removal was developed by combining dielectric barrier discharge(DBD)and negative pulse corona(NPC).The effects of gas composition(O2,CO2,and H2 O)on NO removal were investigated with this method,and the effect of alcohols(methanol and ethanol)addition on NO removal was also investigated as well as the reaction mechanisms to enhance the NO removal efficiency.The experimental results showed that O2,CO2,and H2 O had obvious inhibition effects on NO removal,and the negative effects were in the following order:O2>CO2>H2 O.The addition of methanol or ethanol in the reaction system could mitigate the negative effects of O2,CO2 and H2 O on NO removal,and also eliminated the production of N02.The positive effect of alcohols addition with DBD-NPC denitration method was also validated in the simulated flue gas,in which the NOx(NO,NO2)was mainly converted into N2.
