Designing asymmetric PVDF hollow fibres for soluble gas removal
Tailor-made polyvinylidene fluoride (PVDF) asymmetric hollow fibre membranes are employed for the removal of soluble gases, such as H2S or SO2, from waste gas streams. This study focuses on techniques of fabricating and characterizing the PVDF asymmetric hollow fibre membrane used as a stable interface for absorption of H2S or SO2 using an alkaline solution. The effects of operating conditions and the morphological structures of the membranes on the membrane's coefficient, (k) over bar (Am) are examined. Capabilities of the hollow fibre membranes developed for the removal of H2S and SO2 from waste gas streams are evaluated.
