Vapor-Liquid Equilibria Using Unifac


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.













The Thermodynamics of Phase and Reaction Equilibria


Book Description

The Thermodynamics of Phase and Reaction Equilibria, Second Edition, provides a sound foundation for understanding abstract concepts of phase and reaction equilibria (e.g., partial molar Gibbs energy, fugacity, and activity), and shows how to apply these concepts to solve practical problems using numerous clear examples. Available computational software has made it possible for students to tackle realistic and challenging problems from industry. The second edition incorporates phase equilibrium problems dealing with nonideal mixtures containing more than two components and chemical reaction equilibrium problems involving multiple reactions. Computations are carried out with the help of Mathcad®. - Clear layout, coherent and logical organization of the content, and presentation suitable for self-study - Provides analytical equations in dimensionless form for the calculation of changes in internal energy, enthalpy, and entropy as well as departure functions and fugacity coefficients - All chapters have been updated primarily through new examples - Includes many well-organized problems (with answers), which are extensions of the examples enabling conceptual understanding for quantitative/real problem solving - Provides Mathcad worksheets and subroutines - Includes a new chapter linking thermodynamics with reaction engineering - A complete Instructor's Solutions Manual is available as a textbook resource
