“…amine-based absorbents [18] and to be characterized by a large CO 2 /amine transport selectivity [19]. This latter feature is very attractive to enable the use of highly volatile CO 2 absorbents, as it can allow a substantial reduction of the amine concentration in the gas phase leaving the absorber.…”

“…AF2400 flat-sheet samples were prepared as both self-standing films and thin composite membranes and were investigated by means of gas permeation and membrane contactor tests. The choice of AF2400 was dictated by its superior stability towards amines, as demonstrated in literature[18]. The self-supported AF2400 samples were prepared via solvent evaporation method by dropping a calibrated amount of solution (1 wt% of polymer in FC-72) on a round petri dish.…”

“…In this regard, membrane separation is considered as an emerging technology and has numerous advantages over traditional CO 2 and H 2 S adsorption and absorption methods, such as the low energy consumption, the operational simplicity, and the low environmental impact [2], which make it particularly attractive in small- and medium-scale applications [3]. The development of high-performance СН 4 /СО 2 separation membranes with both high permeability and selectivity has been a current issue in recent years [4], while the use of ionic liquids (ILs) in membrane separation processes is one of the fastest growing research topics [5,6,7,8,9]. Many types of membranes and membrane processes containing ILs have been reported, including supported ionic liquid membranes (SILMs), polymerized ionic liquid membranes, polymer/IL gel membranes.…”

Acidic Gases Separation from Gas Mixtures on the Supported Ionic Liquid Membranes Providing the Facilitated and Solution-Diffusion Transport Mechanisms

Nowadays, the imidazolium-based ionic liquids containing acetate counter-ions are attracting much attention as both highly selective absorbents of the acidic gases and CO2 carriers in the supported ionic liquid membranes. In this regard, the investigation of the gas transport properties of such membranes may be appropriate for better understanding of various factors affecting the separation performance and the selection of the optimal operating conditions. In this work, we have tested CH4, CO2 and H2S permeability across the supported ionic liquid membranes impregnated by 1-butyl-3-methylimidazolium acetate (bmim[OAc]) with the following determination of the ideal selectivity in order to compare the facilitated transport membrane performance with the supported ionic liquid membrane (SILM) that provides solution-diffusion mechanism, namely, containing 1-butyl-3-methylimidazolium tetrafluoroborate (bmim[BF4]). Both SILMs have showed modest individual gases permeability and ideal selectivity of CO2/CH4 and H2S/CH4 separation that achieves values up to 15 and 32, respectively. The effect of the feed gas mixture composition on the permeability of acidic gases and permeselectivity of the gas pair was investigated. It turned out that the permeation behavior for the bmim[OAc]-based SILM toward the binary CO2/CH4, H2S/CH4 and ternary CO2/H2S/CH4 mixtures was featured with high acidic gases selectivity due to the relatively low methane penetration through the liquid phase saturated by acidic gases.

“…Many types of membranes and membrane processes containing ILs have been reported, including supported IL membranes (SILMs), polymerized ionic liquid (PIL) membranes, polymer/IL gel membranes. Among the diverse gas mixtures, the most known seem to be the CO2/CH4 separations, associated respectively with the purification of flue gas streams and natural gas processes [10].…”

Nowadays, the imidazolium-based ionic liquids containing acetate counter-ions are attracting much attention as both highly selective absorbents of the acidic gases and CO2 carriers in the supported ionic liquid membranes. In this regard, the investigation of the gas transport properties of such membranes may be appropriate for better understanding of various factors affecting the separation performance and the selection of the optimal operating conditions. In this work, we have tested CH4, CO2 and H2S permeability across the SILM impregnated by 1-butyl-3-methylimidazolium acetate (bmim[ace]) with the following determination of the ideal selectivity in order to compare the facilitated transport membrane performance with the SILM that dissolves acidic gases physically, namely, containing 1-butyl-3-methylimidazolium tetrafluoroborate (bmim[BF4]). Both SILMs have showed modest individual gases permeability and ideal selectivity of CO2/CH4 and H2S/CH4 separation that achieves values up to 15 and 32, respectively. The effect of the feed gas mixture composition on the permeability of acidic gases and permeselectivity of the gas pair was investigated.
