(Liquid+liquid) equilibria for ternary mixtures of (methanol or ethanol+toluene or m-xylene+n-dodecane)

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

“…The effectiveness of extraction of toluene by ethylene glycol from (toluene + n-octane) mixtures is given by the selectivity (S) by the following equation [1]:…”

“…The equilibrium apparatus used in the present work was similar to that used in the previous work [1]. The equilibrium cell is made of glass with a water jacket to maintain a constant temperature (±0.1 K).…”

“…From practical and economical aspects, the (liquid + liquid) extraction is a popular process for separation of aromatic hydrocarbons from alkanes [1][2][3]. Considering the important role of a suitable solvent in the extraction process operations, the research for finding new solvents, in (liquid + liquid) extraction is an ongoing investigation [4][5][6][7][8].…”

Application of stochastic algorithms for parameter estimation in the liquid–liquid phase equilibrium modeling

“…For S6 system, Mohsen-Nia et al [61] reported rmsd values between 1.88-2.85% for NRTL model and 1.17-3.27% for UNIQUAC. Here, the following values were found: 0.87% for UNIQUAC and 1.11% for NRTL, which again demonstrates the consistency of the parameter estimation strategy used in this work compared to literature.…”

(Liquid+liquid) equilibria of (heptane, or hexane, or cyclohexane+toluene+1,3-dimethyl-2-imidazolidinone) ternary systems at T=298.15K

“…Since the aromatic hydrocarbon extraction process is of great value for the petrochemical industry, the separation of aromatic hydrocarbons from alkanes by liquid-liquid extraction has been an area of active research [5][6][7][8][9][10][11][12]. Liquid-liquid extraction is a mass transfer operation in which the feed is contacted with an immiscible or nearly immiscible solvent that exhibits preferential affinity or selectivity towards one or more of the component in the feed.…”
