This book was released on 1992 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents Fortran version of a chemical thermodynamic model for calculating liquid-liquid equilibria in mixtures of organic compounds. The model applies the Gibbs energy minimization method for phase equilibria computation combined with the UNIFAC routine and thermodynamic database for calculating activity coefficients of organic substances in multicomponent organic liquids on the basis of the group contribution theory. The model can be extended without modifications of the Gibbs energy minimization program to take into account also chemical interactions between organic components.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The high pressure phase behaviour of binary fluid mixtures has been extensively studied during the last three decades. There is ample experimental data for a wide variety of binary mixtures and extensive methods for prediction have been developed. In contrast, the investigation of ternary and other multicomponent fluids is in its infancy. Experimental ternary mixture critical data are very rare and theoretical studies have been limited to data correlation rather than genuine prediction. The phase behaviour of ternary and other multicomponent fluid mixtures has many novel aspects which are not manifested in binary mixtures. The properties of ternary mixtures are also likely to be more difficult to characterize experimentally. It is in this context that calculated phase diagrams have an important role in leading the discovery of new phenomena and guiding experimental work. The criteria for phase equilibria of multicomponent fluids with particular emphasis on the critical state are examined in this book, and models for predicting fluid equilibria (e.g., different equations of state) are compared. Particular attention is paid to the critical state of ternary mixtures which has hitherto been largely neglected. The problems associated with predicting ternary equilibria are discussed, and some novel aspects of ternary critical phenomena are illustrated. The books also describes a novel type of critical transition which appears to be a common feature of the equilibria of ternary mixtures. Extensive phase diagrams of a wide range of ternary mixtures including systems containing carbon dioxide, water, nitrogen and tetrafluoromethane as one or more component are presented. The theoretical treatment is detailed in the appendix and a computation of known experimental critical points is also included.

Book excerpt: Phase Equilibrium in Mixtures deals with phase equilibrium and the methods of correlating, checking, and predicting phase data. Topics covered range from latent heat and vapor pressure to dilute solutions, ideal and near-ideal solutions, and consistency tests. Molecular considerations and their use for the prediction and correlation of data are also discussed. Comprised of nine chapters, this volume begins with an introduction to the role of thermodynamics and the criteria for equilibrium between phases, along with fugacity and the thermodynamic functions of mixing. The discussion then turns to some of the phase phenomena which may be encountered in chemical engineering practice; methods of correlating and extending vapor pressure data and practical techniques for calculating latent heats from these data; the behavior of dilute solutions both at low and high pressures for reacting and non-reacting systems; and the behavior of ideal and near-ideal solutions. The remaining chapters explore non-ideal solutions at normal pressures; practical methods for testing the thermodynamic consistency of phase data; and the extent to which the broad aspects of phase behavior may be interpreted in the light of simple molecular considerations. This book is intended primarily for graduate chemical engineers but should also be of interest to those graduates in physics or chemistry who need to use phase equilibrium data.

Available in PDF, EPUB and Kindle. Book excerpt: The report is concerned with the development of a comprehensive computer program for the estimation of multicomponent vapor-liquid equilibria in two phase systems at low to moderate pressures. The system which was developed is referred to as 'the KVALUE routines.' The KVALUE routines consist of approximately 2,000 FORTRAN instructions which require 21,454 words of storage when loaded into an IBM 360/44. Included in the text discussion are the following topics: the thermodynamic criteria for equilibrium, the computation of vapor phase fugacity coefficients using both the virial and the Redlich-Kwong equations of state, the correlation of activity coefficients to liquid phase composition via the equations of Wilson, Van Laar, and Hildebrand, the calculation of standard-state fugacities from thermodynamic considerations and from the popular Chao-Seader correlation, and techniques for evaluating the necessary physical properties and parameters. Also included is a discussion of Marquardt's method and the manner in which this algorithmic process is implemented to obtain a solution to the system of nonlinear equations which must be solved when estimating multicomponent vapor-liquid equilibria.
