For ammonia flue gas 做學desulfurization (FGD), 離商the sulfite to sulfate oxida還會tion is very critical for industrial暗對 applications. This paper爸購 reports a novel corona plas黃做ma-induced oxidation techniqu笑她e to convert concentrated 習拍ammonium sulfites to sulfates in男河 an aqueous solution. The門錯 streamer corona plasmas are g能件enerated with a dc sup化什erimposed ac power source. Ammoni光服um sulfite solution is spray綠線ed in a reactor by using two-phase 文頻nozzles. When the sulfite concentratio門話n is around 1–3 mol/L , the oxidation efficiency after on票說e-cycle processing is i在區n the range of 20–60%. Multiple-cy公湖cle treatments can be used to 遠姐improve the oxidation 物工efficiency. The energy con門學sumption is around 20 通森W/ mol . Based on the present investigati相長ons, we anticipate that an indus員了trial plasma-assisted ammonium FGD can 作會be applied in industries.
