Nonlinear Behavior of Reactor-Separator and Reactor-Distillation Networks: Influence of the Energy Balance Formulation

In previous work the influence of different formulations of the energy balance equation on a single heated flash and on a simple reactor-flash ( single tray) system was investigated. In the present work this study is extended to reactor-distillation systems with recycle, i.e. the separator is now a multi tray column. Focus is on the influence of the energy balance formulation on uniqueness, stability, and dynamics of the system.
