Liquid+liquid equilibria for ternary mixtures of (solvent+aromatic hydrocarbon+alkane)

Experimental and theoretical study of quaternary (liquid+liquid) equilibria for mixtures of (methanol or water+ethanol+toluene+n-decane)

“…The selectivity factor, which is a convenient measure of the separation power of the solvent for the extraction of the toluene from n-decane mixtures, is defined as [3]:…”

“…There currently is a considerable interest in using suitable solvents for extracting aromatic hydrocarbons from alkane mixtures used in chemical and oil industries [1][2][3]. From a practical and economical point of view, liquid to liquid extraction is an attractive field of investigation [4].…”

Liquid–liquid equilibrium (LLE) data for ternary mixtures of {aliphatic+p-xylene+[EMpy][ESO4]} at T=313.15K

“…The latter approach is the most common separation technique recently employed in petrochemical industries [3]. Despite its broad application, the toxic and volatile nature of the employed solvents such as sulfolane [1,[5][6][7][8][9][10][11], glycols [12,13] and propylene carbonate [14] as well as the high cost of solvent recovery, makes researchers to seek for other possible solvents. One of the potential candidates to supersede conventional organic solvents is ionic liquid.…”

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

“…A vast number of papers presenting liquid-liquid equilibrium data of systems including aliphatics + aromatics + sulfolane [6,[28][29][30][31][32] have been published in the literature. Nevertheless, only few data of systems containing aliphatics + aromatics + glycols [43][44][45][46][47][48] is available.…”
