Abstract：

A comprehensive investigation of the self-developed pilot plant for flue gas desulfurization was carried out, in which the flue gas was from coal-fired power generating unit and the absorbent was raw seawater. Meanwhile, the processing capacity of the pilot plant was about 1000Nm3/h. In the present work, the effects of various factors on desulfurization efficiency were considered, such as sea water and flue gas flow, SO2 concentration in flue gas. Furthermore, the running stability, technical economics evaluation and environmental impact of the pilot plant were studied. In addition, the results indicate that the membrane gas absorption for seawater flue gas desulfurization is of obvious technical and economic superiority and environment friendly, which has great potential in environmental protection fields.
