An industry-scale semi-wet te科微chnological process for fl錢信ue gas desulfurization by co湖數rona discharges is recommende女相d. Its characteristics are: (1) it 西男uses an ac/dc power supply to generate筆謝 uniformly distributed strea秒靜mer plasmas; (2) it uses a partitioned 不員wet reactor system i去一n which SO2 in the flue gas is absorbed with風玩 ammonia water in its thermal chemi做舞cal reaction stage and the 小一generated solution is rep街姐eatedly sprayed and transfer話作red at an appropriate flow rate to the 能花successive plasma react村關ion stage under the condition紙家s of keeping liquid flow in報們 balance. In the plasma stage, SO行水2 absorption by the li也通quid is enhanced by the electric w金謝ind and the sulfites in the 高吧solution experiences p花對lasma oxidization; (3) drying up the 購店end liquid to produce po玩廠wder-typed byproduct a綠黃nd discharging the end gas after heat 時間exchange with the hot 還樂gas at the inlet. Through a 子紅pilot test of 12,000 Nm3/h capacity of flue gas with an init外科ial SO2 concentration of about 500 ppm, results市關 of desulfurization r村線ate >95%, energy consumption in t知街he reactor 1.8 W/Nm3 , ammonia slip less than 5 ppm公我 and qualified fertilizer byproduc中工t are obtained.
