Gas transport properties of poly(ethylene oxide-co-epichlorohydrin) membranes

Influence of relative humidity on carbon dioxide sorption in wheat gluten films

“…Silicon polymers Stern et al (1987) 2-8 35 Polyimides Okamoto et al (1989) 4 8 0 Poly(3-hydroxybutyrate) Miguel et al (1999) 3 3 5 Polyimide-silica composite Joly et al (1997) 35 25 Fluorinated polyimides Tanaka et al (1993) 22-35 35 Poly(ethylene oxide-co-epichlorohydrin) with 90 mol% ethylene oxide Charmette et al (2004) interface at equilibrium. Large permeability coefficients result either in large coefficient diffusion D i , limited affinity for the gas phase (high c G i ), high affinity for the membrane material (small c m i ) or a low saturation vapour pressure ðp G isat Þ.…”

Preparation and characterization of acrylonitrile–butadiene–styrene/poly(vinyl acetate) membrane for CO2 removal

“…CO 2 removal from gas streams are taken into account as an important instance in industries; some examples are: CO 2 capturing from off-gas or flue gases for greenhouse gas emissions control (CO 2 /N 2 separation), natural gas upgrading, enhanced oil recovery, landfill gas recovery (CO 2 /CH 4 separation), etc. [2][3][4][5][6].…”

Membrane-based carbon capture from flue gas: a review

“…of 12 Barrers, and CO 2 /N 2 pure gas selectivity of 48 at 35 C. PE under similar conditions showed CO 2 permeability of 13 Barrers with the cost of very low CO 2 /N 2 selectivity of 13. Charmette et al (2004) studied properties of cross-linked membranes prepared from PEO and poly(epichlorohydrin) (PEP) at different composition ratios. At PEO/PEP mixtures with high PEO concentrations such as 93/7 and 96/4, a high CO 2 /N 2 selectivity above 62 was observed.…”
