Abstract
AbstractThe present study is a first attempt towards utilizing a Ag(II)/Ag(I) based mediated electrochemical oxidation (MEO) system for the simultaneous clean‐up of NOx and SO2 gases in simulated flue gas‐air mixtures on a laboratory‐scale scrubber column integrated with an electrochemical reactor, and to rationalize the efficient application of the MEO process for flue gas abatement and pollution control. Experiments were carried out with individual gas components followed with the mixture, and the effect of input NO and input SO2 concentrations was examined on the NOx and SO2 removal efficiencies at 20°C. Complete oxidation of NO to NO2 with 100% NO removal efficiency and 80% NOx removal efficiency was achieved along with 100% SO2 removal efficiency, highlighting the potentially far greater efficiency of the Ag(II)/Ag(I) based MEO system in functionality and selectivity. Significant research work in this direction can be anticipated in the near future.
