Abstract

In this paper we formulate a dynamic model of a multi-product reactive distillation (RD) column. Such model can be used to determine optimal product switching policies. The dynamic RD model is hybrid in its nature; the material balances, the kinetics, etc. are continuous, while the product switching policy is discrete. Therefore, we propose to formulate the model in the language Chi. This language is a hybrid process algebra for modeling, simulation, verification and control of hybrid systems. We demonstrate that a reactive distillation process can be conveniently modeled in Chi and we also show how to implement a PI controller with anti-windup to track the changes in product quality by adaptation of the feed flow. The Chi simulator is used to obtain the presented simulation results.
