Book excerpt: Vapor-Liquid Equilibrium, Second Edition covers the theoretical principles and methods of calculation of equilibrium conditions from various experimental data and the elements of measuring technique, as well as the instruments for the direct determination of the equilibrium compositions of the liquid and vapor phases of the system. The book discusses the relations necessary for the thermodynamic treatment of the equilibrium between the liquid and vapor phase of a system; the concept of an ideal solution and auxiliary thermodynamic functions; and the activity and the activity coefficient. The text also describes vapor-liquid equilibrium in real systems (electrolytes and non-electrolytes) and in systems whose components (i.e. temperature, pressure, and composition of phases) mutually react according to several stoichiometric equations. The criteria of purity of substances and the methods of measuring temperature; low, medium, and high pressures; the pressures of the saturated vapors at given temperatures; and the boiling points at given pressures used in laboratory work in the field of vapor-liquid equilibrium are considered. The book also tackles the methods for the direct determination of equilibrium data (distillation, circulation, static, dew and bubble point, and flow methods). The text concludes with a review of the literature on the systems whose vapor-liquid equilibrium data had been measured and reported to the beginning of 1954. Workers in the chemical industry who deal with problems of distillation and rectification will find the book useful.

Download or read book Vapor Liquid Equilibria Using Unifac written by Aage Fredenslund and published by Elsevier. This book was released on 2012-12-02 with total page 393 pages. 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: Vapor-liquid equilibrium (VLE) data are necessary for the design and operation of distillation processes. It is absolutely impossible to determine a distillation process without VLE data. The author of this book has had much experience designing and constructing distillation processes and towers and knows that VLE data must be easily retrievable, readily comprehensible, and precise. This volume contains the most important VLE data for 1,446 binary systems with Wilson parameters determined by computer processing. The data are also presented graphically. The Wilson equation, which is known as one of the most applicable to multicomponent systems, is employed for computer-aided determination of the optimum parameters using the non-linear least squares method.

This book was released on 2009-08-27 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Working Guide to Vapor-Liquid Phase Equilibria Calculations offers a practical guide for calculations of vapor-phase equilibria. The book begins by introducing basic concepts such as vapor pressure, vapor pressure charts, equilibrium ratios, and flash calculations. It then presents methods for predicting the equilibrium ratios of hydrocarbon mixtures: Wilson's correlation, Standing's correlation, convergence pressure method, and Whitson and Torp correlation. The book describes techniques to determine equilibrium ratios of the plus fraction, including Campbell's method, Winn's method, and Katz's method. The remaining chapters cover the solution of phase equilibrium problems in reservoir and process engineering; developments in the field of empirical cubic equations of state (EOS) and their applications in petroleum engineering; and the splitting of the plus fraction for EOS calculations. Includes explanations of formulas Step by step calculations Provides examples and solutions

Download or read book Vapor Liquid Equilibrium of Ternary Systems written by Khalid Farhod and published by LAP Lambert Academic Publishing. This book was released on 2011-05-17 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obtaining accurate values for vapor-liquid equilibrium (VLE) is very important in the design of separation equipment and some industrial applications in chemical engineering. So in order to obtain accurate properties of VLE attention has been turned to calculate them from equations of state (EOS), noting that those equations of state are strongly nonlinear as well as inaccurate results may by obtained when they are applied to nonideal and polar systems. To overcome this problem efforts were directed to modify or improve EOS and their mixing and combining rules. In this book, isobaric vapor- liquid equilibrium for ternary systems has been measured at 101.325 KPa. The measurements were made in recirculating equilibrium still with circulation of both the vapor and liquid phases. . In this book the calculation of VLE K-values is done by using the modified Soave Redlich and Kwong (SRK), modified Peng and Robinson (PR) equations of state and the proposed method that uses the new, three-parameter, temperature dependency form alfa function for the attractive term A of the Peng-Robinson equation of state.

This book was released on 2017-10-27 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
