Book Description
This thesis comprises of two parts. The first part is the determination of vapor-liquid equilibrium data at atmospheric pressure and 55°C for the ternary system n-hexane-ethyl alcohol-benzene and for the three possible binary systems n-hexane-ethyl alcohol, n-hexane-benzene and ethyl alcohol-benzene which constituted the ternary system. A modified Gillespie equilibrium still is employed to conduct the investigation. The equilibrium data for the three binary systems and the ternary system appear to be consistent as shown from the thermodynamic consistency tests. The experimental results indicate that two binary systems, namely, n-hexane-ethyl alcohol and ethyl alcohol-benzene form azeotrope at 760 nm. Hg. and 55°C. The ternary system deviates considerably from ideal liquid phase behavior. However, no ternary azeotrope is found from the experiment. The second part presents a method for predicting binary vapor-liquid equilibrium data at various conditions if the equilibrium data for the system concerned are available over the complete concentration range at any one isothermal or isobaric condition. The proposed method is limited to nonazeotropic solutions.

Vapor-Liquid Equilibria Using Unifac
Author: Aage FredenslundPublisher: Elsevier

Category : Technology & Engineering

Pages : 393
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.
Phase Equilibrium in Mixtures

Book Description
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.
