“…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].…”
“…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.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
