Application of simplified PC - SAFT to glycol ethers / Ane S. Avlund in Industrial & engineering chemistry research, Vol. 51 N° 1 (Janvier 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 1 (Janvier 2012) . - pp. 547–555 Titre : Application of simplified PC - SAFT to glycol ethers Type de document : texte imprimé Auteurs : Ane S. Avlund, Auteur ; Georgios M. Kontogeorgis, Auteur ; Michael L. Michelsen, Auteur Année de publication : 2012 Article en page(s) : pp. 547–555 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Glycol  ethers  Methoxyethanol  Ethoxyethanol Résumé : The simplified PC-SAFT (sPC-SAFT) equation of state is applied for binary glycol ether-containing mixtures, and it is investigated how the results are influenced by inclusion of intramolecular association in the association theory. Three different glycol ethers are examined: 2-methoxyethanol, 2-ethoxyethanol, and 2-butoxyethanol. Vapor–liquid and liquid–liquid equilibria of miscible and immiscible, self- and cross-associating mixtures are considered, including the closed-loop liquid–liquid equilibrium of 2-butoxyethanol–water. The results are finally compared to other association models.

Modeling systems containing alkanolamines with the CPA equation of state / Ane S. Avlund in Industrial & engineering chemistry research, Vol. 47 N°19 (Octobre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°19 (Octobre 2008) . - p. 7441–7446 Titre : Modeling systems containing alkanolamines with the CPA equation of state Type de document : texte imprimé Auteurs : Ane S. Avlund, Auteur ; Georgios M. Kontogeorgis, Auteur ; Michael L. Michelsen, Auteur Année de publication : 2008 Article en page(s) : p. 7441–7446 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Equation  of  state  Alkanolamines  Liquid-liquid  equilibria  Vapor-liquid  equilibria Résumé : An association model, the cubic-plus-association (CPA) equation of state (EoS), is applied for the first time to a class of multifunctional compounds (alkanolamines). Three alkanolamines of practical and scientific significance are considered; monoethanolamine (MEA), diethanolamine (DEA), and methyl diethanolamine (MDEA). Vapor pressures and liquid densities, as well as solvatochromic parameters and mixture liquid−liquid equilibria (LLE) data with alkanes are used to estimate the five pure-compound parameters. Vapor−liquid equilibria (VLE) calculations for cross-associating mixtures, especially those with water, are used in the validation of the parameters. The influence on the results of the association scheme, cross-association combining rules, interaction parameters, and the data available is discussed also, in connection with other aqueous cross-associating mixtures previously studied using the CPA equation of state (alcohols, amines, and glycols).
