Abstract:
 As one of the air pollutants,SO2 is the main cause of acid rain and PM2.5. Itnot only destroyed the ecosystem balance,but also affected the respiratory system and lung function. In this paper,PES hollow fiber membrane contactor was studied for the SO2 removal and absorption. The effects ofSO2 concentration,pressure differential, length of the membrane fiber, packing density and other factors on SO2 absorption performancewere investigated usingNaOH solution. And mass transfer performance of membrane contactor was also studied. The durable and stability of membrane contactor has been proved by long-term experiment. The effect of membrane wetting on membrane transfer mass was also been discussed. The results showed that when the stages of membrane contact, the length of membrane fiber, and absorption liquid flowrate increased, SO2 removal efficiency would increase. And SO2absorption fluxincreased as SO2 inlet concentration and liquid flow rate increased.The results of a long-term experiment indicated that SO2absorption flux dropped by 42% during the initial 10h because of membrane wetting.Then the absorption flux maintained at 2.8 × 10-4mol/m2s and unchanged after 390min.Based on the model of membrane wetting effect on total mass transfer resistance, membrane mass transfer resistance would be the main mass transfer resistance in the process of absorption, which accounted for 73% of the overall mass transfer resistance.
