저온 플라즈마 공정에 의한 효율적인 탈황 및 탈질

초록

In this study, we have analyzed the removal efficiencies of SO2 and SO2/NO by the pulsed corona discharge process and investigated the effects of several process variables on those removal efficiencies systematically. The effects of process variables such as applied voltage, pulse frequency, residence time, and initial concentrations of reactants (NO, SO2, NH3, H2O, and O2) on the removal efficiency were analyzed. As the applied voltage, the pulse frequency or the residence time increases or as the O2 or the H2O or the NH3 concentration in the inlet feed gas stream increases, the SO2 removal efficiencies and the simultaneous removal efficiencies of SO2/NO also increase. These experimental results can be used as a basis to design the pulsed corona discharge process to remove NOx and SOx.
