For ammonia flue gas desulfurization (些可FGD), the sulfite to sulfat錯姐e oxidation is very critical人知 for industrial applicat拿飛ions. This paper reports a novel cor到問ona plasma-induced oxidation techniqu又鐵e to convert concent機森rated ammonium sulfites to sul術說fates in an aqueous solution. 睡錯The streamer corona plasmas are g船物enerated with a dc superimposed 國看ac power source. Ammo裡她nium sulfite solution is spr看章ayed in a reactor by using two-phas頻歌e nozzles. When the sulfit懂遠e concentration is around 1–3 mol/L , the oxidation effi商熱ciency after one-cycle proc南音essing is in the range of 20–60%. Mul通紙tiple-cycle treatments can 動跳be used to improve the oxidation effi老和ciency. The energy consumption is 腦放around 20 W/ mol . Based on the present investi笑關gations, we anticipate tha唱朋t an industrial plasma-assist現習ed ammonium FGD can be ap可下plied in industries.
