Dynamic behaviour of reactive distillation system

Reactive distillation columns incorporate both phase separation and chemical reaction. They have economic advantages over conventional reactor and/or separator, particularly for reversible reactions in which the conversion of reaction is limited with the chemical equilibrium. Because both reaction and separation occur in a single vessel operating at some pressure, the temperatures of reaction and separation are not independent. Thus, reactive distillation is limited to systems in which the temperatures of reactions are compatible with those for vapor-liquid separation. The process integration design and dynamic simulation of simple reactive distillation systems was studied. This is an abstract of a paper presented at the 8th World Congress of Chemical Engineering (Montreal, Quebec, Canada 8/23-27/2009).
