ABSTRACT離討:An industry-scale semi-wet 文長technological process for flue gas d照湖esulfurization by corona discharg說空es is recommended. Its characteristi土算cs are: (1) it uses an ac/dc power 裡還supply to generate uni刀讀formly distributed s坐長treamer plasmas; (2)老亮 it uses a partitione船哥d wet reactor system in which SO市近₂ in the flue gas is absorbed 高藍with ammonia water in 歌能its thermal chemical reaction st快哥age and the generated so房謝lution is repeatedly spray科冷ed and transferred at an 術樂appropriate flow rate to the 吧可successive plasma reaction sta跳兒ge under the conditions of 件明keeping liquid flow in balance. In 議船the plasma stage, SO₂ absorption by the liquid is enhanced by不店 the electric wind and the sul訊你fites in the solution experiences plasm姐通a oxidization; (3) dryin文關g up the end liquid to p動微roduce powder-typed byproduct and disc那近harging the end gas after hea自電t exchange with the hot gas at th西的e inlet. Through a pilot test 購好of 12,000 Nm³/h capacity of flue gas with an init內東ial SO₂ concentration of about 5師還00 ppm, results of de音弟sulfurization rate >95%, ener短畫gy consumption in the react土門or 1.8 W/Nm³ , ammonia slip less than 5 麗通ppm and qualified fertilizer 腦長byproduct are obtaine他河d.
