“…Separation and transport of a CO 2 =N 2 mixture through a liquid membrane of diethanolamine (Guha, Majumdar, & Sirkar, 1990), CO 2 =CH 4 through a liquid membrane of amine solutions (Teramoto, Nakai, & Ohnishi, 1996) and removal of CH 4 from a ternary mixture of CO 2 , H 2 S and CH 4 (Way & Noble, 1989), and H 2 S from CO 2 (Kreulen, Smolders, & Versteeg, 1993) are other examples of the possible applications. Some other applications include transport and separation of 1-hexane and 1,5-hexadiene through a ÿlm of a Naÿon membrane (Koval & Spontarellit, 1988), ethene and ethane through Naÿon membranes (Eriksen, Aksnes, & Dahl, 1993), oleÿn/para n mixture through polymer membranes (Ho & Dalrymple, 1994;VanZyl & Linkov, 1997), hydrocarbons mixture using ion exchange membranes (VanZyl, Kerres, & Cui, 1997) and styrene and ethylbenzene through ionomer membranes (Koval, Spontarelli, & Noble, 1989;Koval, Spontarelli, & Thoen, 1992).…”

An analytical expression for the facilitation factor of component A across a liquid membrane is derived in case of an instantaneous reaction A(g) + B(l) ⇔ AB(l) inside the liquid membrane. The present expression has been derived based on the analytical results of Olander (A.I.Ch.E. J. 6(2) (1960) 233) obtained for the enhancement factor for G-L systems with bulk. The analytical expression for the facilitation factor allows for arbitrary di usivities of all species involved and does not contain any simpliÿcation or approximations. The facilitation factor starts from the value of unity, goes through a maximum and then reduces back to unity as the equilibrium constant is increased. The maximum facilitation factor occurs at higher values of the equilibrium constant as the ratio of the permeate-complex over carrier di usivity is reduced whereas the maximum facilitation factor occurs at the same value of the equilibrium constant for all values of DA=DB (ratio of the permeate over carrier di usivity). A similar behavior is seen for the ux of A as a function of the equilibrium constant. The facilitation factor remains constant with changes in the ÿlm thickness whereas the ux of A reduces with an increase in the thickness of the ÿlm. A linear increase of the facilitation factor and ux of A are seen with increasing initial carrier concentration.

ABSTRACT:In this contribution, the synthesis and characterization of novel ion-exchange blend membranes which contain the SO 3 Ag group for the application in the perstractive separation of alkene-alkane mixtures, where the Ag ϩ ion serves as facilitated transport site for the alkene via formation of a pi complex with the alkene double bond, is presented. In this part of the article, the transport properties of the following blend membrane types are described: (1) acid-base blend membranes of ortho-sulfonesulfonated polysulfone (PSU) with ortho-sulfone-diaminated PSU; (2) blend membranes of ortho-sulfone-sulfonated PSU with unmodified PSU; (3) blend membranes of ortho-sulfone-sulfonated PSU with ortho-sulfone disilylated PSU.

Effect of feed pressure and anion properties on facilitated olefin transport through solid polymer electrolyte (SPE) membranes containing silver ions in poly(2‐ethyl‐2‐oxazoline) (POZ) or poly(N‐vinyl pyrrolidone) (PVP) matrix has been investigated. Propylene solubility data in various SPE films are analyzed using the dual sorption model. The results indicate that the solubility coefficient of propylene in polymeric matrices was unexpectedly high although it was unmeasurably low in corresponding pure polymer. The equilibrium constants of the reaction between carrier and propylene for SPE films containing AgBF4 are higher than those with AgCF3SO3 for both polymers investigated. In addition, saturated amounts of propylene coordinated to the silver ions in SPE films with AgBF4 are higher than those with AgCF3SO3, resulting in higher propylene permeance in polymer electrolytes containing AgBF4.
