The CO 2 solubility data in the ionic liquid (IL) 1-allyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide, methanol (MeOH), and their mixture with different combinations at temperatures of 313.2, 333.2, and 353.2 K and pressures up to 6.50 MPa were measured experimentally. New group binary interaction parameters of the predictive universal quasichemical functional-group activity coefficient (UNIFAC)-Lei model, which has been continually advanced by our group, were introduced by correlating the experimental data of this work and the literature. The consistency between experimental data and predicted results proves the reliability of UNIFAC-Lei model for CO 2 -IL-organic solvent systems. The newly obtained parameters were incorporated into the UNIFAC property model of Aspen Plus software to optimize a conceptual process developed for the purification of a CO 2 -containing gas stream. The simulation results indicate that the use of IL either mixed with MeOH or purely considerably lowers the process power consumption and improves the process performance in terms of CO 2 capture rate and solvent loss. ðx 1 Þ n 5Fðm 1 ; m 2 ; m 3 ; m 4 ; m 5 Þ (1) Figure 2.

“…Ionic liquids (ILs) are new substances with specific physico-chemical properties used in catalysis, electrochemistry, new materials and with large extraction possibilities [1][2][3][4][5][6][7][8]. The most popular use of ILs in recent years is as high selectivity extrahents in the separation of aromatic/aliphatic hydrocarbons [9][10][11][12][13], sulfur compounds/fuels (alkanes) [14][15][16][17][18][19], alkenes from alkanes [20][21][22][23][24], or water/butan-1-ol [25][26][27][28][29][30][31], or in 2-phenylethanol/water separation [32][33][34][35].…”

“…That is why a vast amount of experimental work has dealt with measurements of the SLE/LLE/VLE phase diagrams in ILs-based systems. The phase equilibria in systems that contain ILs has been the object of investigation in our group from many years [33][34][35][36][37][38][39][40][41][42][43][44][45].…”

The examples of phase equilibria in binary systems, solid/liquid (SLE), liquid/liquid (LLE), vapor/liquid (VLE), as well as liquid/liquid equilibria in ternary systems mainly containing ionic liquids (ILs), or the infragrance materials, or pharmaceuticals with molecular organic solvents, such as an alcohol, or water, or hydrocarbons, are presented. The most popular correlation methods of the experimental phase equilibrium data are presented, related to the excess Gibbs free energy models such as Wilson, universal-quasichemical, UNIQUAC and non-random two-liquid model, NRTL as well as several popular theories for the modeling of the phase equilibria and excess molar enthalpy, HE in binary or ternary mixtures are presented: the group contribution method (Mod. UNIFAC) and modified UNIFAC model for pharmaceuticals and lattice theory based on non-random hydrogen bonding (NRHB). The SLE, LLE, or VLE and HE of these systems may be described by the Perturbed-Chain Polar Statistical Associating Fluid Theory (PC-SAFT), or a Conductor-like Screening Model for Real Solvents (COSMO-RS). The examples of the application of ILs as extractants for the separation of aromatic hydrocarbons from alkanes, sulfur compounds from alkanes, alkenes from alkanes, ethylbenzene from styrene, butan-1-ol from water phase, or 2-phenylethanol (PEA) from water are discussed on the basis of previously published data. The first information about the selectivity of extrahent for separation can be obtained from the measurements of the limiting activity coefficient measurements by the gas–liquid chromatography technique. This review outlines the main research work carried out over the last few years on direct measurements of phase equilibria, or HE and limiting activity coefficients, the possibility of thermodynamic modeling with emphasis on recent research achievements and potential for future research.

A mass of LLE data for extracting alcohol from its mixture by ILs have been published. − Saien et al have investigated the efficiency of ILs in extracting acetone from its aqueous solutions . Domínguez et al have explored LLE of alkane + aromatic compounds + ILs systems, Letcher et al and García et al have investigated the feasibility for ILs as solvent in separating benzene + alkane mixture, Ahmed et al have measured the LLE of hexadecane + sulfur compound + ILs systems.…”

Selection of a suitable solvent is the key for the extraction process. In this work, four ionic liquids were selected as solvent for extracting butanol, the ternary liquid–liquid equilibria (LLE) data for systems of heptane + butanol + {[HMIM][BF4] (1-hexyl-3-methylimidazolium tetrafluoroborate), [OMIM][BF4] (1-octyl-3-methylimidazolium tetrafluoroborate), [HMIM][OTf] (1-hexyl-3-methylimidazolium trifluoromethansulfonate), and [HMIM][NTf2] (1-hexyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)imide)} were measured at 298.15 K and atmospheric pressure. The extraction capacity of four ILs in the separation of butanol from heptane + butanol mixture was estimated by the selectivity (S) and solute distribution ratio (β), and the influence of the structure and anion of IL on the extraction efficiency was investigated. The experimental LLE data were correlated by using NRTL and UNIQUAC models.
