| 제목 | Absorption of SO2 from flue gas using PVDF hollow fiber membrane contactors |
| 초록 | The micro-porous asymmetric PVDF hollow fiber membranes were prepared from commercially available polyvinylidene fluoride(PVDF) and N-methyl-2-pyrrolidine by the dry-jet wet phase inversion process. Mean pores size and effective porosity were evaluated by the gas permeation method. The membrane morphology was examined with help of scanning electron microscope. PVDF hydrophobic membranes were tested for the absorption of SO2. The effect of various operating variables such as gas/liquid flow rates, inlet SO2 concentration, concentration of absorbent and nature of absorbent on the SO2 removal efficiencies has been investigated. The absorption efficiency of aqueous solutions of various chemicals such as Na2SO3, Na2CO3, NaHCO3 and NaOH has been compared and Na2CO3 was found to be the most promising absorbent among them. |
