Modeling Multicomponent Gas Separation Using Hollow-Fiber Membrane Cohtactors
A model developed for multicomponent gas separation using hollow-fiber contactors permits simulation of cocurrent, countercurrent, and crossflow contacting patterns with permeate purging (or sweep). The numerical approach proposed permits simulation to much higher stage cuts than previously published work and provides rapid and stable solutions for cases with many components, with widely varyin...
متن کاملGas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane
In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...
متن کاملPolyimide Hollow Fiber Membranes for Co2 Separation from Wet Gas Mixtures
Matrimid®5218 hollow fiber membranes were prepared using the dry-wet spinning process. The transport properties were measured with pure gases (H2, CO2, N2, CH4 and O2) and with a mixture (30% CO2 and 70% N2) in dry and wet conditions at 25 °C, 50 °C, 60 °C and 75 °C and up to 600 kPa. Interesting values of single gas selectivity up to 60 °C (between 31 and 28 for CO2/N2 and between 33 and 30 fo...
متن کاملPreparation and characterization of polyethylene/ glass fiber composite membrane prepared via thermally induced phase separation method
Grinded glass fiber (GGF) embedded high density polyethylene (HDPE) membranes were prepared via thermally induced phase separation method. FESEM images showed that all the membranes had leafy structure, indicating a solid-liquid mechanism during phase separation. The results of EDX and TGA analyses confirmed that the fibers were dispersed in the HDPE matrix uniformly. Normalized water flux of t...
متن کاملHigh selectivity ZIF-93 hollow fiber membranes for gas separation.
Zeolitic imidazolate framework-93 (ZIF-93) continuous membranes were synthesized on the inner side of P84 co-polyimide hollow fiber supports by microfluidics. MOFs and polymers showed high compatibility and the membrane exhibited H2-CH4 and CO2-CH4 separation selectivities of 97 (100 °C) and 17 (35 °C), respectively.
