Abstract:A new methods for desulfurization was required to overcome problems with desulfurization by gas ionization discharge, including the large size of the plasma source, high energy consumption, and the need for the synergy of a traditional desulfurization method. Active oxygen species (e.g. O2+, O(1D), O(3P), O3) and HO2- initiators were injected under low-flow and high-concentration conditions into a flue to reach with H2O in the flue gas to generate ·OH radicals, which can oxidize micro SO2 from a large number of the flue gas to produce H2SO4 liquid without the use of absorbents and catalysts and other technologies coordination. As the gas temperature was 30℃ and the molar ratio was between 3 to 4, at which point the SO2 removal efficiency was 94.6%, and the SO42- concentrations in the recovered acid liquid was 9.3 g/L.
