Book Description
Vapor-Liquid Equilibria Using UNIFAC: A Group-Contribution Method focuses on the UNIFAC group-contribution method used in predicting quantitative information on the phase equilibria during separation by estimating activity coefficients. Drawing on tested vapor-liquid equilibrium data on which UNIFAC is based, it demonstrates through examples how the method may be used in practical engineering design calculations. Divided into nine chapters, this volume begins with a discussion of vapor and liquid phase nonidealities and how they are calculated in terms of fugacity and activity coefficients, respectively. It then introduces the reader to the UNIFAC method and how it works, the procedure used in establishing the parameters needed for the model, prediction of binary and multicomponent vapor-liquid equilibria for a large number of systems, the potential of UNIFAC for predicting liquid-liquid equilibria, and how UNIFAC can be used to solve practical distillation design problems. This book will benefit process design engineers who want to reliably predict phase equilibria for designing distillation columns and other separation processes.

Book Description
Excerpt from Vapor-Liquid Equilibrium of Binary Mixtures in the Extended Critical Region, Vol. 1: Thermodynamic Model There is, therefore, a need for a current and detailed explanation of the theory and techniques, which this report is intended to satisfy. The mostly self - contained exposition should be useful for a novice as well as for an individual, of either scientific or engineering background, experienced in phase equilibrium calculations. Although this first report of a series of two contains many new results and insights not published previously, the primary justification for the work is its wide - ranging success in correlating vle data as described in Part II of this series. Furthermore, the Leung - Griffiths formalism is in part rigorous thermodynamics and in part approximation and assumption. Some of our newly introduced parameters can be given heuristic justification, whereas others are purely empirical. The exposition is organized to make clear the logical structure of the method, to identify what is exact and what is approximate, and to present arguments justifying the approximations. In Sec. 2 we define the transformed variables of the Leung - Griffiths model and translate the fundamental laws of thermodynamics into relationships among these variables. The description to this point is general and devoid of assumptions and approximations. With the proper motivation, in Sec. 3 the equation specifying the independent variable (thermodynamic potential), as a function of the dependent variables, is constructed. This step corresponds in the conventional approach to the specification of an equation of state. Specific emphasis is placed on the conformity with simple scaling - law behavior and the thermodynamic consistency of the model. In Secs. 4 and 5, certain heretofore unspecified functions of the independent variables are defined explicitly. The representation of the critical locus in Sec. 6 completes the description of the model. New results and features are summarized in Sec. 7.

Book Description
Information necessary to solve scientific or engineering problems is often so vast, that the need arises to lump information together into a more manageable subset in order to proceed. The idea of lumping is one which is used, more or less consciously, in a large variety of fields. The thermodynamics and kinetic behavior of multicomponent mixtures is an area where the requirements of lumping have been clearly identified and the techniques and results of lumping have been analyzed in considerable detail. This book comprises the proceedings of a Symposium on Kinetic and Thermodynamic Lumping of Multicomponent Mixtures which was held at the American Chemical Society Meeting in Atlanta, GA, in April 1991. Papers presented at the symposium consisted of both invited and contributed papers. Each invited paper was a review of a subfield within the landscape of the symposium while the contributed papers contain detailed analyses of specific problems. The symposium brought together active researchers in this field to report on and discuss the progress which has been made in the lumping of mixtures of very many components for a number of different applications, and to identify the important problem areas which still remain. This volume will serve both as an introduction to anyone entering the field, and as a reference work for more experienced researchers.

Book Description
The classic guide to mixtures, completely updated with new models, theories, examples, and data. Efficient separation operations and many other chemical processes depend upon a thorough understanding of the properties of gaseous and liquid mixtures. Molecular Thermodynamics of Fluid-Phase Equilibria, Third Edition is a systematic, practical guide to interpreting, correlating, and predicting thermodynamic properties used in mixture-related phase-equilibrium calculations. Completely updated, this edition reflects the growing maturity of techniques grounded in applied statistical thermodynamics and molecular simulation, while relying on classical thermodynamics, molecular physics, and physical chemistry wherever these fields offer superior solutions. Detailed new coverage includes: Techniques for improving separation processes and making them more environmentally friendly. Theoretical concepts enabling the description and interpretation of solution properties. New models, notably the lattice-fluid and statistical associated-fluid theories. Polymer solutions, including gas-polymer equilibria, polymer blends, membranes, and gels. Electrolyte solutions, including semi-empirical models for solutions containing salts or volatile electrolytes. Coverage also includes: fundamentals of classical thermodynamics of phase equilibria; thermodynamic properties from volumetric data; intermolecular forces; fugacities in gas and liquid mixtures; solubilities of gases and solids in liquids; high-pressure phase equilibria; virial coefficients for quantum gases; and much more. Throughout, Molecular Thermodynamics of Fluid-Phase Equilibria strikes a perfect balance between empirical techniques and theory, and is replete with useful examples and experimental data. More than ever, it is the essential resource for engineers, chemists, and other professionals working with mixtures and related processes.
