The conventional techniques, which are being used to clean the flue gases such as catalytic reduction method for NO removal, wet and dry scrubbers for SO2 removal and ESP for particulate removal, are becoming more expensive and less suitable for small plants and mobile emission sources. Non-thermal plasma (NTP) techniques utilizing electrical discharges give an innovative approach for economical solution of gas cleaning. The studies present recent work on applying the electrical discharge plasma technology for treating gaseous pollutants, in general, and nitric oxide, in particular, as this is one of the major contributors to air pollution. The present works focuses attention on dielectric barrier discharge technique for nitric oxide removal from simulated gas compositions and investigate the effect of various operating parameters on the NO removal efficiencies at room temperature. The effects of various parameters, viz. discharge power, gas velocity, initial NO concentration (ppm), gas mixture composition, etc., on NO removal efficiency are discussed. Studies are divided into two parts: in the nitrogen atmosphere and argon atmosphere respectively, in order to investigate the effect of various operating parameters on the NO removal efficiencies at room temperature. The results in nitrogen atmosphere indicate that the influence of the discharge power, oxygen content and different initial concentration on NO removal efficiency are also studied. Conclusion that increasing discharge power is in favor of the NO removal. Adding oxygen reduce the NO removal efficiency significantly, and changing the NO initial concentration effected on NO removal efficiency but nor as good as the factors of discharge power, oxygen content. In the argon atmosphere, the dielectric barrier discharge require lower voltage level. The effect of the discharge power, gas velocity and oxygen content on NO removal efficiencies are studied and some conclusions be obtained, increasing discharge power and lowing flue gas velocity would conducive to removal, adding oxygen would hinder the removal of NO. Further result and comparative study of various cases be presented in this paper.
