Available in PDF, EPUB and Kindle. Book excerpt: In previous chapters, we have seen the fundamental criteria for phase equilibria and how the phenomenological phase behavior and separation technology of real mixtures are determined by their constituent molecular interactions. Our purpose in this chapter is to present the properties of fluids and the models for the prediction of thermodynamic properties and phase equilibria. These models are classified as predictive models using only pure component properties and semiempirical models based on a molecular thermodynamic approach. Finally, the chapter highlights the importance of the class of mixture and molecular interactions of its components in the selection of thermodynamic models for phase equilibrium calculations.

Book excerpt: Using an applications perspective Thermodynamic Models for Industrial Applications provides a unified framework for the development of various thermodynamic models, ranging from the classical models to some of the most advanced ones. Among these are the Cubic Plus Association Equation of State (CPA EoS) and the Perturbed Chain Statistical Association Fluid Theory (PC-SAFT). These two advanced models are already in widespread use in industry and academia, especially within the oil and gas, chemical and polymer industries. Presenting both classical models such as the Cubic Equations of State and more advanced models such as the CPA, this book provides the critical starting point for choosing the most appropriate calculation method for accurate process simulations. Written by two of the developers of these models, Thermodynamic Models for Industrial Applications emphasizes model selection and model development and includes a useful “which model for which application” guide. It also covers industrial requirements as well as discusses the challenges of thermodynamics in the 21st Century.

Book excerpt: Computational tools allow material scientists to model and analyze increasingly complicated systems to appreciate material behavior. Accurate use and interpretation however, requires a strong understanding of the thermodynamic principles that underpin phase equilibrium, transformation and state. This fully revised and updated edition covers the fundamentals of thermodynamics, with a view to modern computer applications. The theoretical basis of chemical equilibria and chemical changes is covered with an emphasis on the properties of phase diagrams. Starting with the basic principles, discussion moves to systems involving multiple phases. New chapters cover irreversible thermodynamics, extremum principles, and the thermodynamics of surfaces and interfaces. Theoretical descriptions of equilibrium conditions, the state of systems at equilibrium and the changes as equilibrium is reached, are all demonstrated graphically. With illustrative examples - many computer calculated - and worked examples, this textbook is an valuable resource for advanced undergraduates and graduate students in materials science and engineering.

Book excerpt: The selection of the most adequate thermodynamic model in a process simulation is an issue that most process engineer has to face sooner or later. This book, conceived as a practical guide, aims at providing adequate answers by analysing the questions to be looked at. The analysis (first chapter) yields three keys that are further discussed in three different chapters. (1) A good understanding of the properties required in the process, and their method of calculation is the first key. The second chapter provides to that end in a synthetic manner the most important equations that are derived from the fundamental principes of thermodynamics. (2) An adequate description of the mixture, which is a combination of models and parameters, is the second key. The third chapter makes the link between components and models, both from a numerical (parameterisation) and physical (molecular interactions) point of view. Finally, (3) a correct view of the phase behaviour and trends in regard of the process conditions is the third key. The fourth chapter illustrates the phase behaviour and makes model recommendations for the most significant industrial systems. A decision tree is provided at the end of this chapter. In the last chapter, the key questions are reviewed for a number of typical processes. This book is intended for process engineers, who are not specialists of thermodynamics but are confronted with this kind of problems and need a reference book, as well as process engineering students who will find an original approach to thermodynamics, complementary of traditional lectures

Book excerpt: This textbook deals with the theoretical basis of chemical equilibria and chemical changes and emphasizes the properties of phase diagrams. The author treats the field from a modern perspective. He takes into account the dramatic changes in the methods of applying thermodynamics caused by the development both of computer operated programs for sophisticated equilibrium calculations and of extensive databases containing thermodynamic parameter values for individual phases from which all thermodynamic properties may be calculated. This new situation has inspired a new approach to the teaching of basic thermodynamics. Illustrative examples of thermodynamic modeling are also given, and the book contains many exercises and worked solutions. This modern text will be of value to undergraduate and graduate students in materials science and chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: High pressures play a more and more important role in modern technology. Examples are the supercritical fluid extraction of medical drugs and dyes from biological material, the handling of compressed or liquefied gases (including natural gas or hydrogen), the operation of modern thermal power plants, or various technical processes for controlled particle formation. High-Pressure Fluid Phase Equilibria, Second Edition enables understanding of the complicated phase behaviour that fluid or fluid mixtures (liquids, gases, or supercritical phases) can exhibit at elevated pressures. The underlying thermodynamic equations are explained, and robust algorithms for the computation of such equilibria (including solid–fluid equilibria) are proposed. Since the publication of the first edition of this book there have been many new developments, for instance differential equation methods for the computation of phase equilibria, accurate numerical differentiation, high-precision equations of state (e.g., the GERG model). Moreover, more detail and explanation has been added on important topics that were only briefly examined in the original book to better assist the reader, such as expansion processes and chemical reactions). The book remains invaluable as a single resource for grasping the intricacies of fluid phase behaviour. It enables readers to write or improve their own computer programs for the calculation of phase equilibria. It will appeal to graduate students of chemical engineering and university research staff involved in chemical engineering of supercritical fluids or the physical chemistry of fluids; the book can also serve as the basis of lectures or advanced students’ seminars. Comprehensively presents the complex world of phase equilibria (binary and ternary) and the various methods for computing phase equilibria, whilst carefully considering the relevant pressure and temperature ranges Introduces phase diagram classes, how to recognize them, and how to identify their characteristic features Presents rational nomenclature of binary fluid phase diagrams Includes problems and solutions for self-testing, exercises, or seminars New to this Edition: Presentation of the phase equilibria models is extended and expanded There are now more descriptions on more equations of state, especially the PCSAFT EoS Features new chapter on nonisothermal applications and chemically reactive systems and extensive updates and additions to all existing chapters

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Equations of state (EoS) have proved to be a reliable tool in chemical engineering thermodynamics for modeling the physical properties of complex systems. Various types of EoS have been developed based on different theories. For various reasons, some have become more popular for use in industry and academia. Of the popular EoS, two were chosen for investigation in this thesis. The first one was the Perturbed Chain- Statistical Associating Fluid Theory (PC-SAFT), an equation derived based on statistical mechanics and the second was the Peng-Robinson (PR) EoS, a cubic EoS commonly used in industry. In this work, the prediction capabilities of these two EoS were compared for several properties. The analysis began with an evaluation of their use in the prediction of the saturation properties of pure components and derivative properties from ambient conditions to the supercritical range. The particular derivative properties studied include the isochoric and isobaric heat capacities, the speed of sound, and the isothermal compressibility. In general, it was concluded that PC-SAFT outperforms PR in all cases. Next, the same primary and derivative properties of several binary and a select ternary mixture were studied. To improve agreement with experimental data, a binary interaction parameter was introduced and fitted to binary mixture vapor - liquid equilibria (VLE) data. This procedure drastically improved the accuracy of the models compared to the case where no binary interaction parameter used for the case of VLE predictions. However, for the case of the derivative properties, the use of the binary interaction parameter to ensure a more accurate representation of the interactions between molecules had only a marginal effect on the prediction of these properties. Finally, phase equilibria of hydrates were studied. As EoS for fluids are not designed to predict the properties of solid phases, the van der Waals-Platteeuw model was incorporated to allow for the prediction of three-phase equilibrium conditions of various hydrate formers. Specifically, this work focused on the equilibrium of a water-rich liquid phase, a hydrate phase and a vapor phase rich in a hydrate former. In all cases, calculations of the solid hydrate phase properties are based on the Kihara potential. This potential requires three parameters to be defined; initial values for which were found through a review of the literature. The accuracy of the predictions of the three-phase equilibrium is highly dependent on the reliability of these parameters. Thus, one of the parameters, the so-called Îæ parameter, was fitted to hydrate equilibrium data and resulted in a significant improvement in the accuracy of predictions of both PC-SAFT and PR EoS. The new set of parameters was then used to predict the three-phase equilibrium of several binary, ternary and quaternary mixtures of hydrate forming agents. Several conclusions are drawn from this work, including the observation that the accuracy of the models is reduced when the number of components increases.
