The reactive distillation unit is one of the most important and "delicate" functional components of a complex chemical plant. While modeling and simulation of steady-state operation has become standard today using a number of well-known specialized software tools, very little is known about dynamic modeling in the open literature. Due to the complexity of the process, references on this topic mention the many difficulties in building a dynamic model that could be suitable for nu- merical integration. Dynamic modeling is useful to understand the behavior of such a complex plant. However, the most important challenge in using an appropriate modeling tool is the design and tuning of the control system for such a reactive distillation process.
