Abstract
This paper presents the nonlinear dynamic analysis of an ideal two-reactant-two product
reactive distillation. The impact of disturbance magnitudes and directions on openloop
stability of the system is studied. An analysis of the physicochemical phenomena
present in reactive distillation processes that, under certain operational conditions,
causes special types of nonlinear behavior is carried. Operating two-reactant-two-
product reactive distillation with excess of heavy reactant is found to enhance openloop
stability, but decreases the products purity. However, excess of more volatile reactant
drifts the system to another state. It is found that openloop reactive distillation system
has a better dynamics when operated with fixing reflux ratio instead of reflux rate.
Keywords: Reactive distillation, nonlinear dynamic simulation, system stability
