A review on the polymeric hollow fibers membranes for gas separation has been conducted. In order to deyelop high performance membranes for gas separation, there are a few technology challenges awaiting the chemical engineers to overcome. There are four major challenges, namely: 1) material selection and synthesis; 2) fabrication of hollow fiber membranes with an ultra- thin dense selective layer; 3) materials against plasticization; and 4) aging. In each area, we summarize the scientific accomplishments and technical difficulties.

Synergistic action of non-solvent induced phase separation in preparation of poly(vinyl butyral) hollow fiber membrane via thermally induced phase separation

引用

Journal of Central South University 2014年第6期21卷 2184-2190页

作者：邱运仁漆静韦玉清 School of Chemistry and Chemical Engineering Central South University

A systematic study of air gap distance effects on the structure and properties of poly(vinyl butyral)hollow fiber membrane via thermally induced phase separation(TIPS)has been carried *** results show that the hollow fiber membrane prepared at air gap zero has no skin layer; the pore size near the outer surface is larger than that near the inner surface; and the special pore channel-like structure near the outer surface is formed,which is quite different with the typical sponge-like structure caused by TIPS and the finger-like structure caused by non-solvent induced phase separation(NIPS),because of the synergistic action of non-solvent induced phase separation at air gap *** pore size gradually decreases from outer surface layer to the intermediate layer,but increases gradually from intermediate layer to the inner surface *** the increase of air gap distance,the pore size near the outer surface gets smaller and a dense skin layer is formed,and the pore size gradually increases from the outer surface layer to the inner surface *** permeability of the hollow fiber membrane decreases with air gap distance,the water permeability decreases sharply from 45.50×10-7 to 4.52×10-7 m3/(m2·s·kPa)as air gap increases from 0 to 10 mm at take-up speed of 0.236 m/s,further decreases from 4.52×10-7 to 1.00×10-8 m3/(m2·s·kPa)as the air gap increases from 10 to 40 *** the breaking strength and the elongation increase with the increase of air gap *** breaking strength increases from 2.25 MPa to 4.19 MPa and the elongation increases from 33.9% to 132.6% as air gap increases from 0 mm to 40 mm at take-up speed 0.236 m/s.

CHARACTERIZATION OF MIXED GAS PERMEATION THROUGH hollow fiberS

引用

化工学报 2000年第S1期51卷 74-78页

作者： Wang R. Liu S.L. and cao Y.M. (Environmental Technology Institute, Singapore, 18 Nanyang Drive, 637723) (Institute of Materials Research & Engineering, 3 Research Link Singapore, 117602)

We have studied the mixed gas permeation in hollow fiber membrane modules using two approaches: namely, the co- current plug flow model and the complete mixing model with the combination of experimental data. Elucidation was made to determine the permeance of CO2 and CH4 and the selectivity of CO2/CH4 in a polyimide hollow fiber membrane permeator It is found that the intrinsic gas separation properties of hollow fibers for mixed gases can be accurately determined based on (1) the cocurrent plug now model, and (2) the complete mixing model with the assumption of averaged retentate concentration of the feed and the retentate outlet.
