For ammonia flue gas desulf動喝urization (FGD), the sulfite森能 to sulfate oxidation is very critic務得al for industrial applicat有錢ions. This paper reports a novel coro現美na plasma-induced oxid自地ation technique to con醫學vert concentrated amm綠業onium sulfites to sulfates in市子 an aqueous solution. T暗刀he streamer corona plasma煙子s are generated with a d雪討c superimposed ac power source房視. Ammonium sulfite solu師好tion is sprayed in a rea湖海ctor by using two-phase nozzles. When月也 the sulfite concentra線動tion is around 1–3 mol/L , the oxidation effic機農iency after one-cycle pro她來cessing is in the range of 20–60%. Mul制女tiple-cycle treatments can be use舞吧d to improve the oxid唱日ation efficiency. The energy con知物sumption is around 20 W/ mol . Based on the pres慢船ent investigations, we anticipate t去多hat an industrial plasma-assisted am商樂monium FGD can be applied弟紙 in industries.
