“…Taking into account good chemical stability of different highly permeable glassy polymers confirmed by the FTIR analysis [14,29,30], the duration of aging experiments was substantially shortened by annealing of PTMSP membranes at 100°C.…”

“…It was already shown that PTMSP as a membrane material possesses long-term chemical and mechanical stability at typical MGD conditions -amine-based solvent, trans-membrane pressure up to 40 bar and temperature 100 °C [7]. Furthermore, PTMSP is a barrier material towards chemical solvents such as aqueous solutions of alkanolamines [7] and some physical solvents like water [8] and ionic liquid [9]. Details about the development of these membranes are described elsewhere [10].…”

“…The above problems related to unwanted wetting of pores can be solved by using membranes with a non-porous selective layer based on hydrophobic polymers [18][19][20][21][22][23][24]. Additional resistance provided by this dense membrane layer can be diminished by the use of polymers with high permeability with respect to CO 2 .…”

“…Additional resistance provided by this dense membrane layer can be diminished by the use of polymers with high permeability with respect to CO 2 . Obviously, hydrophobic glassy polymers with a high free-volume fraction can be considered as advantageous membrane materials for gas/liquid contactors [21,24]. For example, a polymer with gas permeability, Poly[1-(TriMethylSilyl)-1-Propyne] (PTMSP), shows good barrier properties towards industrial chemical absorption liquids at a trans-membrane pressure of 40 bar but, at the same time, it is permeable for CO 2 [21,24].…”

This combination of good membrane barrier properties and high CO 2 flux offers evident benefits for a gas-liquid membrane contactor, which can be used not only for CO 2 absorption but also for the regeneration of CO 2 absorption liquids.…”

Re´sume´-Re´ge´ne´ration de solutions d'alcanolamine dans un contacteur a`membrane base´sur un nouveau polynorborne`ne -Un nouveau polyme`re vitreux a`haute perme´abilite´, le poly[bis (trime´thylsilyl)tricyclononene] (PBTMST), est propose´pour la premie`re fois pour une utilisation dans un contacteur gaz-liquide a`membrane pour la re´ge´ne´ration de liquides d'absorption riches en CO 2 (de´sorption de CO 2 ). Ce mate´riau membranaire posse`de une bonne stabilite´chimique et de bonnes proprie´te´s barrie`re pour de nombreuses alcanolamines (solutions de 30 % poids de MEA, DEA, MDEA, AMP, DEAE ou AEAE) dans des conditions typiques de re´ge´ne´ration (T = 100°C). Les e´tudes des proprie´te´s de transport des gaz du PBTMST (a`100°C et sous 1 a`40 bar) montrent que les coefficients de perme´abilite´al 'oxyge`ne, a`l'azote et au dioxyde de carbone tendent a`diminuer puis a`se stabiliser apre`s les 6 a`8 premie`res heures de mesure. Ce comportement peut eˆtre explique´par une relaxation partielle de la structure de volume libre du PBTMST. Aucune de´gradation a`haute tempe´rature du mate´riau polyme`re n'a pu eˆtre confirme´e par analyse IR. De plus, ce mate´riau membranaire conserve des coefficients de perme´abilite´aux gaz e´leve´s, supe´rieurs a`ceux des mate´riaux conventionnels utilise´s dans les contacteurs a`membrane. Un contacteur gaz-liquide a`membrane fabrique´a`partir d'une membrane dense de PBTMST pre´sente de performances bonnes et stables. En particulier, le taux de charge en CO 2 d'une solution de die´thanolamine (30 % poids) peut eˆtre re´duit de 0,05 a`0,34 mole/mole via un simple passage a`travers le re´ge´ne´rateur a`membrane a`100°C et a`pression e´leve´e. Il semble que le taux de de´sorption soit principalement controˆle´par la phase liquide, une diminution de l'e´paisseur membranaire de 50 % (de 31 a`21 lm) n'apportant qu'une ame´lioration de 1,5 a`8,5 % de la re´ge´ne´ration de la DEA. show that permeability coefficients of oxygen, nitrogen and carbon dioxide initially tend to decrease, and then level off after first 6-8 hours of operation. This behavior can be explained by partial relaxation of the free-volume structure of PBTMST, no chemical degradation of polymer material at high temperature was confirmed by IR analysis. At the same time, this membrane material preserves high gas permeability coefficients which are higher than those of conventional materials used in the membrane contactors. Gas-liquid membrane contactor based on dense PBTMST membrane shows a good, stable performance; particularly, CO 2 loading in diethanolamine solution (30 wt%) can be reduced for 0.05-0.34 mole/mole by single pass through the membrane desorber at 100°C and elevated pressure. It seems that desorption rate here is mainly controlled by liquid phase because decreasing of membrane thickness by 50% (from 31 to 21 lm) leads to improvement of DEA regeneration only by 1.5-8.5%.
