Abstract:
Oxidizing NO to more soluble NO2 has been proposed as a promising method for enhancing NO removal in conventional FGD processes. In this paper, the roles of gas components (O2, H2O) and reaction temperature in NO2 removal were discussed by comparing the NO2 absorption characteristics in and without the presence of SO2. It was found that the presence of SO2 in the flue gas could enhance NO2 removal. The effects of O2, H2O and reaction temperature had a high dependence on the presence of SO2. Without the presence of SO2, H2O and O2 concentration had negligible influence on NO2 removal, while higher reaction temperature could accelerate NO2 absorption. However, reaction temperature did not affect NO2 removal in the presence of SO2, and NO2 removal increased with increasing relative humidity but decrease with O2 concentration increasing.
