Non linear behaviour of coupled reactor separator systems

Back
Abstract:
We will discuss the non linear behaviour of processes with integration of reaction and separation. The primary focus is to understand the origin of different non linear behavior using a fundamental approach. At first a single stage reactive distillation process will be investigated. It will be shown that the system can exhibit steady state multiplicity only when the reactant is more volatile than the product since under these conditions the reaction rate is self inhibiting. We will then discuss the behavior of a reactor coupled to a downstream separator through a recycle. The effect of three different control configurations on the non linear behavior of the coupled system will be compared. We will discuss which of these is ideal from the point of view of operating the coupled system. The effect of delays ( lack of it) on the stability will also be highlighted.
