Vapor-liquid Equilibrium Data Collection: Aqueous-organic systems

Separation processes are a multi-billion dollar business. In the United States alone there are more than 40,000 distillation columns which require approximately 7.0 % of the total US energy consumption for operation. Azeotropic data and zeotropic information are essential for the optimal design and synthesis of distillation processes. The book highlights the best way to separate azeotropic systems using hybrid or specialized distillation processes such as pressure swing, azeotropic or extractive distillation. This extensive two-volume compilation covers nearly all data currently available for binary and higher systems. This knowledge is the key for the successful separation of these azeotropic systems. The reader will be inspired by the sheer volume of data for more than 18800 systems involving approximately 1700 compounds. These data are carefully evaluated, documented and arranged according to molecular formula for easy access. The best thermal separation conditions for industry and environmental protection can be achieved through this practical source. In addition to chemical engineers and physical chemists, scientists active in process engineering and environmental protection and will find themselves fully equipped to deal with any separation task.

The only textbook that applies thermodynamics to real-world process engineering problems This must-read for advanced students and professionals alike is the first book to demonstrate how chemical thermodynamics work in the real world by applying them to actual engineering examples. It also discusses the advantages and disadvantages of the particular models and procedures, and explains the most important models that are applied in process industry. All the topics are illustrated with examples that are closely related to practical process simulation problems. At the end of each chapter, additional calculation examples are given to enable readers to extend their comprehension. Chemical Thermodynamics for Process Simulation instructs on the behavior of fluids for pure fluids, describing the main types of equations of state and their abilities. It discusses the various quantities of interest in process simulation, their correlation, and prediction in detail. Chapters look at the important terms for the description of the thermodynamics of mixtures; the most important models and routes for phase equilibrium calculation; models which are applicable to a wide variety of non-electrolyte systems; membrane processes; polymer thermodynamics; enthalpy of reaction; chemical equilibria, and more. -Explains thermodynamic fundamentals used in process simulation with solved examples -Includes new chapters about modern measurement techniques, retrograde condensation, and simultaneous description of chemical equilibrium -Comprises numerous solved examples, which simplify the understanding of the often complex calculation procedures, and discusses advantages and disadvantages of models and procedures -Includes estimation methods for thermophysical properties and phase equilibria thermodynamics of alternative separation processes -Supplemented with MathCAD-sheets and DDBST programs for readers to reproduce the examples Chemical Thermodynamics for Process Simulation is an ideal resource for those working in the fields of process development, process synthesis, or process optimization, and an excellent book for students in the engineering sciences.
