Feasibility of Sequential Removal of NO and SO2 Using Non-Thermal Plasma and Adsorbent Simultaneously
A sequential removal process of NO and SO2 with low energy-consumption and high removal efficiency was put forward, and its feasibility was investigated through chemical kinetics simulation and experiments. In this removal process, NO removal induces SO2 removal sequentially, and this process will go on the surfaces of some suitable adsorbents. Simulations of De-NO and De-SO2 with non-thermal were carried out in dry gas stream (NO/SO2/N2). The simulation results show that SO2 can be converted to SO3, and SO2 removal efficiency is so small that it can not be observed. Comparison experiments were carried out in the dry gas stream (NO/SO2/N2/O2) with Ar and without Ar respectively, and O2 concentration is only 0.1％. The comparison experimental results show that SO2 can not be removed unless there is Ar in the dry gas stream. The mechanism of De-SO2 in the dry gas stream was obtained through analyzing the experimental results and some research results in related literatures. The experimental results and analyzing results all indicate that SO2 can be removed and SO2 removal efficiency mainly depends on electron density. Both the simulations and experiments investigations indicate that the sequential removal of NO and SO2 is feasible.
