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 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.
متن کاملPolystyrene nanoparticle-templated hollow titania nanosphere monolayers as ordered scaffolds
We report a novel multi-step method for the preparation of ordered mesoporous titania scaffolds and show an illustrative example of their application to solar cells. The method is based on (monolayer) colloidal nanosphere lithography that makes use of polystyrene nanoparticles organised at a water–air interface and subsequently transferred onto a solid substrate. A titania precursor solution (t...
متن کاملHollow Colloidosomes Prepared Using Accelerated Solvent Evaporation
We demonstrate a new, scalable, simple, and generally applicable two-step method to prepare hollow colloidosomes. First, a high volume fraction oil-in-water emulsion was prepared. The oil phase consisted of CH2Cl2 containing a hydrophobic structural polymer, such as polycaprolactone (PCL) or polystyrene (PS), which was fed into the water phase. The water phase contained poly(vinylalcohol), poly...
متن کاملEffect of fiber variation on the performance of countercurrent hollow fiber gas separation modules
A theoretical and experimental study of the effects of variable fiber properties on countercurrent hollow fiber gas separation module performance is presented. Variations in ID, slow gas permeance, and selectivity are considered. Variability in any of these properties is detrimental to performance. The drop in performance increases as either property variation or product purity increase, but pe...
