Abstract：

A study of flue gas desulfurization was carried out using self-developed box-type hydrophobic polypropylene hollow fiber membrane contactor with which desalted water, sodium hydroxide and ammonium sulfite were chosen as absorbents. The effects of various influent factors on membrane utility were investigated, such as the absorbent selection, the concentration of the absorbent, the gas-liquid ratio, the concentration of SO2, the temperature of gas and liquid. Accordingly, the mass transfer performance index system and the evaluation method of membrane contactor were proposed and established. The research results showed that the absorbent concentration, gas-liquid ratio and concentration of SO2 were key factors to the desulfurization efficiency, while the influence of temperature of gas and fluid was not obvious. It is indicated that the membrane utility and desulfurization performance index could be accurate on the condition that a specified concentration of ammonium sulfite solution was chosen as absorbent with the corresponding conditions of temperature, pressure and flue gas concentration.
