ChE 6100 – Advanced Chemical Engineering Thermodynamics – Fall 2008 This is primarily a course in molecular thermodynamics. Molecular thermodynamics advances classical thermodynamics by considering the phases not only as continua, but rather as discrete molecules with their own chemistry. Gibbs and Helmholtz in the 19 th Century developed the very elegant classical thermodynamics, which permits us to calculate unmeasured bulk properties from known bulk properties. Throughout the 20 th Century, many investigators stretched the boundaries of the science to include consideration of intermolecular forces and the prediction of bulk properties from such forces and from statistical mechanics. The crucial contribution was to extend these predictions to mixture properties – which are of greatest interest to chemical engineers. What we shall do in this course will start with a rapid review of undergraduate chemical engineering thermodynamics – as this basis is essential for all we shall do. We shall discuss basic statistical mechanical principles and intermolecular forces. Our real goal is to apply these to the correlation and prediction of phase equilibria – so necessary for a variety of separation and reaction processes. This course is not designed for those of you who will specialize in molecular thermodynamics or statistical mechanics – but rather for those of you who will not. The goal is not for you to be able to do every detailed calculation, but rather to understand the meaning and power of the methods. It is to help you use the tools throughout your career by being able to communicate fruitfully with the experts. It is to help you understand what they can and cannot do. Also we want to develop some intellectual maturity in this area. You will surely learn to read a technical paper and decide if it is right or wrong. But we seek to go further: you should have enough understanding to know if the result is important or trivial, how it might be tested, where else it might be applied, how it fits with other results, how it might be extended. In short, is the paper one more number on the author’s publication list, or an opportunity for you to take it and run? The course covers most of the material in the text and will have some added topics as shown in the outline below, but also it will address a number of questions: What do the theories mean? What are their strengths and limitations? When do you work with first principles, and when do you temper it with
