The Effects of Minor Components on the Gas Separation Performance of Polymeric Membranes for Carbon Capture

Natural gas sweetening—the effect on CO2–CH4 separation after exposing a facilitated transport membrane to hydrogen sulfide and higher hydrocarbons

“…Plasticization of polysulfone is also reported by other researchers, especially at high temperature such as 55 1C and high H 2 S partial pressures, and the diffusivity of other gases present will increase-this is attributed to the presence of H 2 S only, and not by CO 2 [34]. It may therefore also be considered to change the support of this membrane for natural gas with high H 2 S content.…”

Effect of monoethylene glycol and triethylene glycol contamination on CO2/CH4 separation of a facilitated transport membrane for natural gas sweetening

“…The effects of CO 2 on glassy polymer are documented by several researchers in [25][26][27][28][29][30]. A number of studies describing the effects of H 2 S, hydrocarbons, water, and both condensable and non-condensable impurities on different membranes are likewise found in the literature [31][32][33][34][35][36][37][38][39][40][41][42][43][44]. However, no such studies are found on the effects of MEG or TEG in CO 2 /CH 4 separation membrane.…”
