A previously proposed methodology for analyzing the economic performance of different structures of an integrated model predictive regulatory control and on‐line optimization system is illustrated using the simulated case study of a fluid‐catalytic cracker. The economic performance of two previously proposed regulatory control structures, the conventional and riser‐regenerator control structures, is assessed both in isolation and as part of a real‐time optimization system. The results show that the economic performance of the conventional structure is superior when operated in isolation. The theory, however, predicts that an optimally configured real‐time optimization system based on the riser‐regenerator structure will deliver superior performance overall. The predictions of the method were confirmed using Monte Carlo simulations.
