Select Thermodynamic Models for Process Simulation : A Practical Guide using a Three Steps Methodology

The selection of the most adequate thermodynamic model in aprocess simulation is an issue that most process engineer has toface sooner or later.This book, conceived as a practical guide, aims at providing adequateanswers by analysing the questions to be looked at. The analysis(first chapter) yields three keys that are further discussed in threedifferent chapters. (1) A good understanding of the propertiesrequired in the process, and their method of calculation is the firstkey. The second chapter provides to that end in a synthetic mannerthe most important equations that are derived from the fundamentalprinciples of thermodynamics. (2) An adequate description of themixture, which is a combination of models and parameters, is thesecond key. The third chapter makes the link between componentsand models, both from a numerical (parameterisation) and physical(molecular interactions) point of view. Finally, (3) a correct view ofthe phase behaviour and trends in regard of the process conditions isthe third key. The fourth chapter illustrates the phase behaviour andmakes model recommendations for the most significant industrialsystems. A decision tree is provided at the end of this chapter. In thelast chapter, the key questions are reviewed for a number of typicalprocesses.This book is intended for process engineers, who are not specialistsof thermodynamics but are confronted with this kind of problems andneed a reference book, as well as process engineering students whowill find an original approach to thermodynamics, complementary oftraditional lectures
