Abstract
The textbook was developed from course notes that have been used in the undergraduate and graduate chemical engineering classes. My intention is to have a text that cover most of the material required by undergraduate curriculum and extend this idea to the graduate course in phase and chemical equilibria. There are a number of good textbooks that partially fulfill this requirement; however, they are not arranged in a manner that can be easily followed by students or instructors. This textbook starts with a simple model which represents ideal behavior followed by moderate deviation from ideality with application of all up-to-date activity coefficient models. A separate chapter is introduced that covers the azeotropic behavior of non-ideal liquid mixtures that find a wide industrial application, and a brief theoretical review of different methods for separating azeoropic mixtures. Residual properties are then introduced to account for the vapor phase non-ideality using fugacity and fugacity coefficient correlations models followed by the most practical equations of state. A separate chapter is given on the application of Henry's law especially in environmental and enhanced oil recovery practices. Emphasis is given to liquid-liquid, vapor-liquid-liquid and solid-fluid equilibria based on the latest literature publications followed by thermodynamic consistency test models. The importance of phase equilibrium of undefined mixture in oil and gas industry is added. A chapter on chemical equilibrium is given at the end of the textbook starting with basic problems followed by industrial problems at high temperature and pressure. Multi-reactions equilibrium solved by minimization of Gibbs free energy are cited. Many worked-out examples plus end of chapter problems are given in each chapter. Solved problems are based on hand calculator, spreadsheet and a simple MATLAB program calculation without relying heavily on commercial software. A step-by-step procedure starts with simple examples and then progressively advances to more challenging problems for ternary and quaternary system. This procedure will help students or practicing engineers to gain self-confidence to fully understand and practice real process or design problems
