(431d) Practical Aspects in Using Distillation VLE and Enthalpy Models

Distillation is a very common Unit Operation today and various simulation tools make it very easy to run a simple distillation tower. Behind that simulation is the “heart” of that tower. That “Heart” is the VLE and enthalpy model that the user has chosen. Frequently, users are inexperienced at understanding the background and the limitations of the model they have chosen. It is the intent of this presentation to take the authors practical experiences, with some common distillation applications, and show where today’s user can benefit from these experiences. Model choices will be discussed as well as some practical methods to vet a model properly before it is rigorously employed.
