Based on the material balance; energy balance and chemical reaction kinetics; a dynamic mathematical model for catalytic reforming unit (CRU) was developed. The distributed parametermodel was transformed into a lumped parameter and a solution was brought about by two-dimensionLaplace transform and polynomial approximation methods. Simulation results showed that the model couldsufficiently lead to the major dynamic effects that occurred in an actual CRU. The model has been appliedto the dynamic simulation and training simulator for training of startup, shut down, normal operation andcritical failures in CRU.
