Experimental vapour–liquid equilibrium data of the quaternary system Methanol (1) + Isopropyl alcohol (2) + Water (3) + Glycerol (4) along with Isopropyl alcohol (2) + Glycerol (4) and Isopropyl alcohol (2) + Water (3) binary data at atmospheric and sub-atmospheric pressures

Uncertainty quantification and global sensitivity analysis of continuous distillation considering the interaction of parameter uncertainty with feed variability

“…The VLE was modelled with the non-random two-liquid model (NRTL), which has been successfully applied to distillation of alcohol-water systems (Kurihara et al, 1993;Puentes et al, 2018;Soujanya et al, 2016Soujanya et al, , 2010Yang et al, 2011). The NRTL model correlates the activity coefficients with the molar fractions in the liquid phase.…”

Systematic identification method for data analysis and phase equilibria modelling for lipids systems

“…This group has also been used Bessa et al [46] to describe the LLE behaviour for lipids. Original UNIFAC with published parameters is not able to correctly describe the VLE for glycerol-alcohol systems [62]. For this reason a new group defining the whole glycerol molecule, GLY, is introduced with the aim of improving the glycerol-alcohol predictions.…”

“…7). This objective function, Eq 6, takes into account also the regularization term [61,62] Where P experimental and P calculated are experimental and calculated pressure, β is an empirical term, set equal to 10 5 , amn is estimated binary interaction parameter, and a 0 mn is the initial value of the binary interaction parameter, in this case Original UNIFAC published parameters value or zero for the GLY interactions.…”

Isobaric Binary Vapor–Liquid Equilibrium of Ethanol + Glycerol and 1-Propanol + Glycerol Systems at 16.0 and 101.3 kPa

“…Faggion et al measured isobaric binary, ternary, and quaternary VLE data ( P–T–w 1 ) at the pressures of (14.0 to 91.2) kPa (ethanol + glycerol), (glycerol + ethanol + NaCl), and (water + ethanol + NaCl + glycerol) systems at 91.2 kPa. Shang et al measured and correlated ternary VLE data ( P–x–y ) for methanol + glycerol + methyl palmitate/methyl laurate/methyl myristate systems at 493.0 and 523.0 K. Soujanya et al measured VLE data of the quaternary system ( T–x ), methanol + isopropanol + water + glycerol using a Sweitoslawsky-type ebulliometer at at 53.33, 66.66, 79.99, and 95.2 kPa. Lemos et al also determined experimentally vapor–liquid equilibrium data ( T–x 1 ) of (ethanol + glycerol) and (tertbutanol + glycerol) systems.…”
