MODELING AND SIMULATION OF COMMERCIAL CATALYTIC NAPHTHA REFORMERS

A simulation model for catalytic reforming has been developed to monit or commercial plant performance. The model consists of various modules to predict temperature and concentration profiles, catalyst deactivat ion and cycle length, inter stage heater duties, recycle gas compositi on and octane number. The lumping details of the feed and reaction sch eme, parameter estimation and model validation details are given. The model numerically integrates the component and energy balance equation s for the combined feed and recycle gas in each reactor and then simul ates flash separator for recycle gas composition. The results of the m odel validated for four different commercial reactors performance are presented.
