Investigation of bulk and interfacial properties for nitrogen and light hydrocarbon binary mixtures by perturbed-chain statistical associating fluid theory combined with density-gradient theory / SongTao Liu in Industrial & engineering chemistry research, Vol. 48 N° 23 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 23 (Décembre 2009) . - pp. 10734–10739 Titre : Investigation of bulk and interfacial properties for nitrogen and light hydrocarbon binary mixtures by perturbed-chain statistical associating fluid theory combined with density-gradient theory Type de document : texte imprimé Auteurs : SongTao Liu, Auteur ; Dong Fu, Auteur ; JianYi Lu, Auteur Année de publication : 2010 Article en page(s) : pp. 10734–10739 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Investigation--Bulk--Interfacial--Properties--Nitrogen--  Hydrocarbon--Binary--Mixtures--Perturbed-Chain--Statistical--Associating--Fluid  Theory--Combined--Density-Gradient Résumé : The perturbed-chain statistical associating fluid theory (PC-SAFT) and density-gradient theory (DGT) are used to construct an equation of state (EOS) for the phase behavior of the binary mixtures of nitrogen and light hydrocarbons. With the molecular parameters and influence parameters respectively regressed from bulk properties and surface tensions of pure fluids as input, both the bulk and the interfacial properties for binary mixtures are investigated. The calculated surface tensions of nitrogen−pentane, nitrogen−hexane, nitrogen−heptane, nitrogen−octane, nitrogen−decane, and nitrogen−toluene binary mixtures are satisfactory as compared to the experimental data. Our results show that PC-SAFT combined with DGT is able to describe the interfacial properties of the binary mixtures of nitrogen−light hydrocarbons in wide pressure range and illustrate the influences of temperature, pressure, and bulk properties on the interfacial properties.

Investigation of vapor-liquid surface tension for carbon dioxide and hydrocarbon mixtures by perturbed-chain statistical associating fluid theory combined with density-gradient theory / Dong Fu in Industrial & engineering chemistry research, Vol. 47 N° 13 (Juillet 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N° 13 (Juillet 2008) . - p. 4490–4495 Titre : Investigation of vapor-liquid surface tension for carbon dioxide and hydrocarbon mixtures by perturbed-chain statistical associating fluid theory combined with density-gradient theory Type de document : texte imprimé Auteurs : Dong Fu, Auteur ; Yuanzhen Wei, Auteur Année de publication : 2008 Article en page(s) : p. 4490–4495 Note générale : Bibliogr. p. 4494-4495 Langues : Anglais (eng) Mots-clés : Carbon  dioxide;  Hydrocarbon  binary  mixtures;  PC-SAFT  theory;  Vapor−liquid  equilibria Résumé : The perturbed-chain statistical associating fluid theory (PC-SAFT) and density-gradient theory (DGT) are used to construct an equation of state (EOS) applicable for the phase behaviors of supercritical carbon dioxide (CO2) and hydrocarbon binary mixtures. In the bulk phases, the nonuniform EOS reduces to PC-SAFT, which is able to accurately describe the vapor−liquid equilibria (VLE) below the critical region. In the vapor−liquid surface, this EOS is able to predict the surface tensions for binary mixtures with the bulk properties and the influence parameters of pure components as input. The surface tensions of CO2−butane, CO2−decane, CO2−benzene, CO2−cyclohexane, and CO2−tetradecane binary mixtures are predicted, and the results are satisfactory compared with the experimental data.
