A rigorous model for the simulation of the dynamic behaviour of distillation column including pressure relief has been developed. This model allows the analysis of the influence of different disturbances (failures) on the dynamic behaviour of a methanol/water column. Disturbances of the cooling medium supply to the condenser and the reflux stream have been examined. In this paper the results of...
