For ammonia flue gas desulfurization北輛 (FGD), the sulfite to 動飛sulfate oxidation is very cri道輛tical for industrial application道林s. This paper reports a nove暗熱l corona plasma-induced oxidation te飛們chnique to convert concentrated am了路monium sulfites to s跳農ulfates in an aqueous solution. T低事he streamer corona plasmas聽唱 are generated with a dc微數 superimposed ac power有村 source. Ammonium sulfite solu唱事tion is sprayed in a react資友or by using two-phase noz花村zles. When the sulfite c動哥oncentration is around 1–3 mo海時l/L , the oxidation efficiency朋制 after one-cycle processing is in th計又e range of 20–60%. Multiple-cy報年cle treatments can be 快空used to improve the oxidati劇下on efficiency. The energy道那 consumption is around 20電訊 W/ mol . Based on the present inve頻紅stigations, we anticipate that 嗎票an industrial plasma亮對-assisted ammonium FGD can be 了美applied in industries.
