Modeling and thermodynamic consistency of solubility data of refrigerants in ionic liquids / Claudio A. Faúndez in International journal of refrigeration, Vol. 36 N° 8 (Décembre 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 8 (Décembre 2013) . - pp. 2242–2250 Titre : Modeling and thermodynamic consistency of solubility data of refrigerants in ionic liquids Titre original : Modélisation et cohérence thermodynamique des données de solubilité des frigorigènes dans les liquides ioniques Type de document : texte imprimé Auteurs : Claudio A. Faúndez, Auteur ; Luis A. Barrientos, Auteur ; José O. Valderrama, Auteur Année de publication : 2014 Article en page(s) : pp. 2242–2250 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Refrigerants;  ionic-liquids;  equation  of  state;  Kwak–Mansoori;  thermodynamic  consistency Résumé : Phase equilibrium data of temperature, pressure and solubility (T-P-x) of hydrofluorocarbon-type refrigerants in different types of ionic liquids over wide ranges of temperatures and pressures are modeled and tested for thermodynamic consistency. Experimental data taken from the literature for nineteen binary mixtures refrigerant + ionic liquids with a total of forty eight isothermal data sets are considered in the study. The modified Peng–Robinson equation of state proposed by Kwak and Mansoori is used for correlating the P-T-x data and a flexible thermodynamic consistency method is applied to analyze the data. Modeling is found acceptable in all cases, meaning that deviations in correlating the data are low, proving at the same time the claimed flexibility of a well-founded model that uses simple van der Waals mixing rules. Thirty eight data sets resulted to be thermodynamically consistent, nine were found to be not-fully consistent and only one set was found to be thermodynamically inconsistent.
