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.

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.
