| description | The objective of this study was to investigate the influence of dope extrusion rates on morphology and gas separation performance of asymmetric polysulfone hollow fiber membranes. Asymmetric poly- Sulfone hollow fiber membranes for gas separation were prepared from a solution consisting of 26.0 wt . % ofpolysulfone, 30.4 wt. % of N, N-dhnethylacetamide, 30.4 wt. % of tetrahydrofuran and 13.2 wt. % ethanol. The dry/wet phase separation process was applied to a drylwet spinning process. Fibers were spun at various dope extrusion rates (DER) ranging from 1.5 - 3.0 cm3/min and hence at different levels of shear. The results Suggest that as the dope extrusion rate is increased, the selectivity will increase until a critical level of shear is reached, beyond which the membrane performance deteriorates. Pressure-normalized-fluxes and selectivities were evaluated by using pure oxygen and nitrogen as test gases. |
