Abstract: | Comparison of equilibrium and nonequilibrium models of a CSTR with total condenser focused on the multiple steady states and
dynamic behaviour was carried out. The steady-state behaviour of the model system, MTBE synthesis from methanol and isobutene
in a reactive distillation column, was studied in terms of the input parameters, i. e. feed flow rate of methanol or butenes, reflux ratio, and mass of catalyst. The dynamic behaviour of the system during the
start-up was investigated and perturbations of manipulated variables were found to cause transitions between the parallel
steady states.
