Abstract：

A Novel G-L membrane contactor was applied for SO2 and NOx removal from flue gas using NaClO2 seawater solution as absorbent, NaHCO3/Ca(OH)2/Ca(ClO)2 as additives. The effects of flow rate of flue gas and absorbent, SO2 content as well as concentration and pH of absorbent on desulfurization and denitrification efficiency were investigated. The results showed that increasing concentration or flow rate of absorbent and decreasing flow rate of flue gas or pH of absorbent could improve desulfurization and denitrification efficiency. NaHCO3/Ca(OH)2/Ca(ClO)2 as additives could facilitate the removing rate of NOx/SO2. It is indicated that membrane based gas absorption technique has potential application to achieve simultaneous desulfurization and denitrification.
