Optimized binary interaction parameters for VLE calculations of natural gas mixtures via cubic and molecular - based equations of state / Mert Atilhan in Industrial & engineering chemistry research, Vol. 51 N° 28 (Juillet 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 28 (Juillet 2012) . - pp. 9687-9699 Titre : Optimized binary interaction parameters for VLE calculations of natural gas mixtures via cubic and molecular - based equations of state Type de document : texte imprimé Auteurs : Mert Atilhan, Auteur ; Santiago Aparicio, Auteur ; Kenneth R. Hall, Auteur Année de publication : 2012 Article en page(s) : pp. 9687-9699 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Thermodynamic  properties  Equations  of  state  Gas  mixture  Natural  gas  Interaction  parameter Résumé : The objective of this study is to analyze the performance of a selected collection of equations of state (EOS) for the prediction of vapor-liquid equilibrium of the components of a typical natural gas mixture. In this work, 13 biparametric, triparametric, and tetraparametric, widely used simple-cubic-type EOS and three complex, but state-of-the-art, molecular-based EOS are used. A simple, one-fluid-based mixing rule was applied for the extension to mixtures of the models. Binary interaction parameters for the different equations were calculated by correlation of available binary vapor―liquid equilibria data in the experimental literature, in wide temperature―pressure ranges, for the key binary systems relevant to natural gases. The results allow one to infer the performance of the different EOS commonly used for phase equilibria analysis in the natural gas industry, and to study how the different complexity of the studied EOS does (or does not) lead to an improvement in the quality of the predictions.

Thermophysical properties of pure ionic liquids / Santiago Aparicio in Industrial & engineering chemistry research, Vol. 49 N° 20 (Octobre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 20 (Octobre 2010) . - pp. 9580–9595 Titre : Thermophysical properties of pure ionic liquids : Review of present situation Type de document : texte imprimé Auteurs : Santiago Aparicio, Auteur ; Mert Atilhan, Auteur ; Ferdi Karadas, Auteur Année de publication : 2011 Article en page(s) : pp. 9580–9595 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Ionic  liquids Résumé : The large collection of thermophysical properties data for liquids available in the open literature is analyzed, describing its importance for industrial purposes. Although there has been a boom of thermophysical properties measurements for these fluids in the past decade, the reported analysis shows that studies have been centered on a limited number of fluids, whereas data collection for the new family ionic liquids is lacking. Measurements have been performed for limited temperature ranges, and pressure effects on the properties are extremely scarce in the literature; remarkable differences among data from different literature sources are reported. The need of sample purity quantification is analyzed together with the strong effect of these impurities on thermophysical properties. Available predictive models for the studied properties are analyzed together with the quality of their predictions. The main conclusion of this review is to point out the need of further systematic thermophysical studies, including for new environmentally friendly ionic liquids, carried out with interlaboratory comparisons, which allow the development of reference data sets.
