Phase equilibria of mixtures containing glycol and n-alkane / Waheed Afzal in Industrial & engineering chemistry research, Vol. 48 N° 24 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 24 (Décembre 2009) . - pp. 11202–11210 Titre : Phase equilibria of mixtures containing glycol and n-alkane : experimental study of infinite dilution activity coefficients and modeling using the cubic-plus-association equation of state Type de document : texte imprimé Auteurs : Waheed Afzal, Auteur ; Martin P. Breil, Auteur ; Pascal Théveneau, Auteur Année de publication : 2010 Article en page(s) : pp. 11202–11210 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Phase--Equilibria--Mixtures--Containing--Glycol--n-Alkane--Experimental--Infinite--Dilution  Activity--Coefficients--Modeling  Using--Cubic-Plus-Association--Equation--State Résumé : In this work, we report the infinite dilution activity coefficients for four n-alkanes (n-pentane, n-hexane, n-heptane, and n-octane) in monoethylene glycol in the temperature range from 298 to 334 K and at atmospheric pressure. Experimental data were measured using a previously described inert gas stripping technique. The new experimental data are compared with the literature data whenever possible. The experimental infinite dilution activity coefficients of several alkanes from n-pentane to n-hexadecane in monoethylene glycol, diethylene glycol, triethylene glycol, and tetraethylene glycol previously reported in the literature, along with the data measured in this work have been modeled using the cubic-plus-association (CPA) equation of state (EoS). Satisfactory results have been obtained using temperature-independent interaction parameters. Useful remarks are presented about the application of infinite dilution activity coefficient data for estimating binary interaction parameters of the CPA EoS for the description of whole vapor−liquid equilibria. Furthermore, the variation in the values of the interaction parameters is discussed for different glycol systems.
