This work presents an enhanced model for the reactor-regenerator system of a UOP fluid catalytic cracking(FCC) unit with a high-efficiency regenerator. The model is derived from fundamental principles; relative toearlier versions, a different cracking deactivation model is considered, and the freeboard region in the regeneratorvessel is also explicitly addressed. The resulting model is fitted to industrial data, using new correlations toestimate the cracking kinetic constants and other important parameters in the FCC heat balance. In thedevelopment of these correlations, only routinely available data and operating variables were considered. Asdemonstrated, parameter estimation allows a good agreement between the simulated results and the availableindustrial data. The procedure followed can, therefore, be used to adapt this model to different units of thesame class. A comparison of the main features of the steady-state and the dynamic behavior of the validatedmodel with previous results is also considered in this paper.
