We have analyzed the temperature dependency of the energy parameter in modern cubic equations of state and modified the original van Laar equation with a view to extending the equation to multicomponent systems. It is found that the consideration of the temperature dependency of the energy parameter has lead to a modified van Laar equation involving additional terms. These extra terms serve to provide some physical significance that can be attached to the van Laar equation to allow it to unambiguously represent the behavior of the excess Gibbs free energy and activity coefficients of nonideal solutions. The final form of the modified van Laar equation for multicomponent mixtures involves two size parameters and an interaction parameter for each of the constituent binary pairs; the latter parameter replaces a term consisting of a combination of the two energy parameters and two size parameters for the components in a binary mixture. For mixtures involving only hydrocarbons the size parameters can be readily calculated from the critical properties by means of any of the cubic equations of state of the van der Waals type.","PeriodicalId":238681,"journal":{"name":"The Open Thermodynamics Journal","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116468256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main idea of such approaches is based on the fact that any reduced model defines a manifold of low dimension imbedded in the system composition/state space. In this respect the decomposition into relatively fast and slow motions due to multiple time scales present in the system is a crucial property of the reacting system. It allows the application of the geometrical framework of slow and fast invariant manifolds to model reduction. Recently developed approaches, namely, the so-called Reaction-Diffusion Manifolds (REDIMs) and Global-Quasi Linearization (GQL) are in the focus of this work. The methods extend and follow the well known ILDM method. The paper discusses both the theoretical basis of the approaches and detailed implementation schemes for studying, reducing and simulating the reacting flows systems. Simple yet containing all features of the reacting flows models of n-heptane/air and syngas/air systems are used to illustrate and verify the methods.","PeriodicalId":238681,"journal":{"name":"The Open Thermodynamics Journal","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131598372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study is related to the phase behavior when water in atmosphere is absorbed into ethanol + gasoline fuel (gasohol) and then possibly separates into two liquid phases in an automobile fuel tank or an underground storage tank. The liquid-liquid equilibria in this study include three ternary systems: ethanol + water + pentane, ethanol + water + hexane, and ethanol + water + cyclohexane; three quaternary systems: ethanol + water + pentane + hexane, ethanol + water + pentane + cyclohexane, and ethanol + water + hexane + cyclohexane; one quinary system: ethanol + water + pentane + hexane + cyclohexane.
