For ammonia flue gas desulfuri冷黑zation (FGD), the sulfi拿見te to sulfate oxidation is very cri舊北tical for industrial ap用呢plications. This paper reports a 文南novel corona plasma-induced 得國oxidation technique to convert con綠鐵centrated ammonium sulfites to sulfa來器tes in an aqueous solution. Th是市e streamer corona plasmas are路光 generated with a dc 科作superimposed ac power source. Ammonium廠筆 sulfite solution is spraye說問d in a reactor by using two-phase技草 nozzles. When the s雨喝ulfite concentration關什 is around 1–3 mol/L , the oxidation effic算南iency after one-cycle processing內視 is in the range of 20–60%. Multip報體le-cycle treatments can be used t厭他o improve the oxidation ef遠線ficiency. The energy c拿你onsumption is around 20 W/ mol . Based on the present們子 investigations, we anticipate 明志that an industrial plasma-assisted am數飛monium FGD can be applied in i火民ndustries.
