Equivalence of the McAllister and heric equations for correlating the liquid viscosity of multicomponent mixtures / Gustavo A. Iglesias-Silva in Industrial & engineering chemistry research, Vol. 49 N° 13 (Juillet 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 13 (Juillet 2010) . - pp. 6250–6254 Titre : Equivalence of the McAllister and heric equations for correlating the liquid viscosity of multicomponent mixtures Type de document : texte imprimé Auteurs : Gustavo A. Iglesias-Silva, Auteur ; Kenneth R. Hall, Auteur Année de publication : 2010 Article en page(s) : pp. 6250–6254 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Correlating  liquid  kinematic  viscosities  McAllister  equations  Heric  equations Résumé : This paper demonstrates the equivalence between two equations for correlating liquid kinematic viscosities: the Heric and McAllister equations. For ternary and multicomponent mixtures, the only difference is in the ternary interaction term. If this term is constant, both equations correlate the viscosity data identically. This approach can prove the equivalence of the Nissan and Grunberg equation and the Frenkel equation to correlate the dynamic viscosity of liquid mixtures. Examples are included for binary and ternary mixtures.

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.
