“…It is noteworthy, however, that all solubilities are in more or less the same range -a result that is confirmed by numerous reference data recorded in various ILs [30,[35][36][37]39,41]. Hence, there is a high probability of overlap especially after consideration of the errors in measurement.…”

“…Latter provoke that the IL weighs generally less in a gas atmosphere than in a vacuum -independent from any gas solvation behaviour. Kumelan et al investigated the solubility of oxygen and CO by means of an optical method, working at high pressure [34][35][36][37][38]. Another pressure depending method is the isochoric saturation technique which was used by Jaquemin et al in order to obtain further knowledge about gas solubilities and the corresponding thermodynamical properties of several sorts of gas in dependence on temperatures between 283 and 343 K [39][40][41].…”

“…This cannot be explained by the uncertainty of experimental data as the relative uncertainty in the experimentally determined mole fraction of dissolved CO is maximum 0.5%, and the relative uncertainty in the observed pressure is less than 2% [11]. Meanwhile, ePC-SAFT cannot quantitatively represent the temperature-effect on the O 2 solubility in [C 6 mim][Tf 2 N].…”

a b s t r a c t ePC-SAFT was used to model the gas solubility in ionic liquids (ILs) ] (n = 2, 4, 6 and 8). For the ePC-SAFT modeling, each IL was considered to be completely dissociated into a cation and an anion. Each ion was modeled as a non-spherical species exerting repulsive, dispersive and Coulomb forces. CO, H 2 and O 2 were modeled as non-spherical molecules exerting repulsive and dispersive forces, and H 2 S was modeled as a non-spherical, associating molecule. ePC-SAFT reasonably predicts the gas solubility in the considered gas/IL mixtures. In order to describe the experimental gas solubilities quantitatively in a broad temperature and pressure range, one ion-specific binary interaction parameter between the IL-anion and the gas was applied, which was allowed to depend linearly on temperature.

“…In recent years, room temperature ionic liquids (RTILs) are showing more and more promising perspectives in industrial waste gases' separation, such as CO 2 [2][3][4][5], SO 2 [6,7], CO [8], H 2 [9] and so on. Due to their favorable properties [10][11][12][13][14], such as wide liquid range, low vapor pressures, high thermal stability, excellent solubility for both polar and nonpolar organic and inorganic substances, using ILs to capture ammonia has attracted much attention recently.…”
