(Liquid+liquid) equilibria for ternary mixtures of (ethylene glycol+toluene+n-octane)

Removal of aromatic hydrocarbons from hydrocarbon mixture using glycols at 303.15 K and 333.15 K and atmospheric pressure: Experimental and calculated data by NRTL and UNIQUAC models

“…For this process organic solvents such as sulfolane , dimethylsulfoxide [33], N-methylpyrrolidone [34], N-formylmorpholine [31,[35][36][37][38][39][40][41] and glycols [42][43][44][45][46][47][48] are used.…”

“…Nevertheless, only few data of systems containing aliphatics + aromatics + glycols [43][44][45][46][47][48] is available. For this reason, experimental LLE data for systems containing decane + toluene + glycols at different temperatures were studied in this paper.…”

Measurement of (liquid+liquid) equilibria for ternary systems of (N-formylmorpholine+benzene+cyclohexane) at temperatures (303.15, 308.15, and 313.15)K

“…In this line of research, the theoretical and experimental studies of (liquid + liquid) equilibrium (LLE) for different systems were presented in the literature. These investigations were focused on the finding a non-toxic, inexpensive, and easily recoverable solvent for (liquid + liquid) extraction processes in the industrial units [1]. Although simulation of extraction process can be used for creating of the best flow sheet, design of the equipments and selection of the optimum operation conditions for a new solvent, the quality of the results depends on the quality of the thermodynamic models to provide the correct description of the dependence on temperature, pressure, and composition in multi-component systems [2].…”

(Liquid+liquid) equilibria for mixtures of (ethylene glycol+benzene+cyclohexane) at temperatures (298.15, 308.15, and 318.15)K

“…Therefore, it is usual to measure the phase equilibrium properties of the liquid systems [3]. In this line of research, the theoretical and experimental studies of (liquid + liquid) equilibrium (LLE) for different systems are presented in the literature [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Considering the important role of a suitable non-toxic, inexpensive, and easily recoverable solvent in the extraction process operations, research into finding new solvents, in (liquid-liquid) extraction is an ongoing investigation [4].…”

“…(Liquid + liquid) equilibrium (LLE) data for a number of ternary mixtures containing solvent (such as ethylene glycol), aromatic, and aliphatic hydrocarbon (such as cyclohexane) have been published in the literature: (ethylene glycol + toluene + n-octane) at three temperatures (295.15, 301.15, and 307.15) K [4]; (cyclohexane + benzene + N-methyl formamide) and (cyclohexene + benzene + N-methyl formamide) at temperatures of (288.15, 298.15, and 308.15) K [5]; (ethylene carbonate + benzene + cyclohexane) at T = (303.15 and 313.15) K and (ethylene carbonate + BTX + cyclohexane) at T = 313.15 K [6]; (methanol + isooctane + cyclohexane) and (methanol + isooctane + cyclohexane + benzene) at T = 303.15 K [7]; (cyclohexane + benzene + sulfolane), (1-hexene + benzene + sulfolane), (hexane + benzene + sulfolane), and (heptane + toluene + sulfolane) at T = (298. 15, 323.15, 348.15, and 373) K [8]; (heptanes + o-xylene + diethylene glycol) over the temperature range of (288.15 to 318.15) K [9]; ternary and quaternary systems including (cyclohexane + 1-heptene + benzene + toluene + sulfolane) at T = 298.15 K [10]; (cyclohexane + benzene + dimethylformamide + ethylene glycol) [11]; (cyclohexane + toluene + sulfolane), and (hexane + toluene + sulfolane) ternary systems [12]; (benzene + cyclohexane + N-methylimidazole, or Nethylimidazole, or N-methylimidazolium dibutylphosphate) at T = 298.2 K and atmospheric pressure [13]; three quaternary systems (nonane + undecane + benzene + sulfolane), (nonane + undecane + toluene + sulfolane), and (nonane + undecane + m-xylene + [14]; (heptane + N-formylmorpholine (NFM) + aromatic hydrocarbons (benzene, toluene, and xylene)) over the temperature range of (298 to 353) K [15].…”
