Multiphase equilibrium calculations from soave equation of state with chang - twu / UNIFAC mixing rules for mixtures containing water, alcohols, and esters / Gui-Bing Hong in Industrial & engineering chemistry research, Vol. 51 N° 13 (Avril 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 13 (Avril 2012) . - pp. 5073–5081 Titre : Multiphase equilibrium calculations from soave equation of state with chang - twu / UNIFAC mixing rules for mixtures containing water, alcohols, and esters Type de document : texte imprimé Auteurs : Gui-Bing Hong, Auteur ; Cheng-Ting Hsieh, Auteur ; Ho-mu Lin, Auteur Année de publication : 2012 Article en page(s) : pp. 5073–5081 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Thermodynamic  properties  Mixing  rule  Equations  of  state  Multiphase  equilibrium Résumé : Various versions of the Soave–Redlich–Kwong (SRK) equation of state incorporating different mixing rules were applied to calculate vapor–liquid equilibrium (VLE), liquid–liquid equilibrium (LLE), and vapor–liquid–liquid equilibrium (VLLE) properties for the systems containing water, alcohols, and esters. The calculated results showed that the SRK equation with the T-type α function and the Chung–Twu (CT) mixing rules embedded in the UNIFAC–Lyngby model (SRK-T/CT–UNIFAC– Lyngby) not only predicts accurately the VLE properties of the constituent binaries but also represents the ternary LLE and VLLE phase behavior reasonably well. Using this model, the vapor pressure data of the pure constituent components are the only required property for the phase equilibrium calculations.

Vapor-liquid-liquid equilibria for aqueous systems with methyl acetate, methyl propionate, and methanol / Cheng-Ting Hsieh in Industrial & engineering chemistry research, Vol. 47 N°20 (Octobre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°20 (Octobre 2008) . - P. 7927-7933 Titre : Vapor-liquid-liquid equilibria for aqueous systems with methyl acetate, methyl propionate, and methanol Type de document : texte imprimé Auteurs : Cheng-Ting Hsieh, Auteur ; Ming-Jer Lee, Auteur ; Ho-mu Lin, Auteur Année de publication : 2008 Article en page(s) : P. 7927-7933 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Vapor−liquid−liquid  equilibrium  (VLLE)  Aqueous  Systems Résumé : Vapor−liquid−liquid equilibrium (VLLE) properties were measured with a static apparatus for mixtures of water + methyl acetate, water + methyl propionate, water + methyl acetate + methanol, and water + methyl propionate + methanol at temperatures ranging from 313.24 to 348.15 K. Both ternary systems exhibit type I liquid−liquid equilibrium (LLE) behavior. By checking with the Othmer−Tobias equation, the experimental tie-line data of these two ternary systems appeared to be consistent. The binary VLLE data were correlated satisfactorily with the UNIQUAC model for water + methyl acetate and water + methyl propionate. While the UNIQUAC model with the parameters determined from the phase equilibrium data of the constituent binaries overestimated the two-liquid-phase regions of the ternary systems, the representation of the binodal loci was substantially improved as the six parameters of the UNIQUAC model were determined simultaneously from the ternary VLLE data.
