Kurzbeschreibung
This text gives a critical presentation of the most common thermodynamic models and highlights the practical advantages, giving recommendations for different applications. It includes worked examples of how the models can be extended to new systems, and provides review tables with the parameters of advanced association models. This resource provides an easy-to-use guide for process engineers without expertise in thermodynamics.
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 & 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 emphasises 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.
