Critical analysis of maxwell’s equal area rule / Karthikeyan Rajendran in Industrial & engineering chemistry research, Vol. 49 N° 16 (Août 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 16 (Août 2010) . - pp. 7687–7692 Titre : Critical analysis of maxwell’s equal area rule : implications for phase equilibrium calculations Type de document : texte imprimé Auteurs : Karthikeyan Rajendran, Auteur ; R. Ravi, Auteur Année de publication : 2010 Article en page(s) : pp. 7687–7692 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Phase  Equilibrium Résumé : The fundamental flaws inherent in Maxwell’s equal area rule are analyzed. Using an alternative principle that overcomes the limitations of Maxwell’s rule, general equations are derived for determining the saturation pressure and other properties associated with the liquid−vapor phase transition given an arbitrary equation of state. The equivalence of the equation for saturation pressure to those available in the literature is proved. It is found that the alternative principle predicts saturation pressures that are significantly different from those calculated using Maxwell’s rule. These results are based on numerical studies on three different equations of state and fifteen substances. Similar results are obtained for the vaporization entropy as well.
