Impact of Production Objectives on Adiabatic FCC Regenerator Control

Abstract In adiabatic FCC regenerators, the classical approach of design and control of continuous stirred tank reactors identify stable steady states. This kind of reactors is a particular case of lumped parameter nonlinear systems. The easiness of regulation of the steady operating states depends on the relationship between system dynamics and control scheme. There have been several attempts for the evaluation of this relationship by systematic approaches, however the nonlinearities of these systems have troubled the evaluation goals. In partially controlled systems, such as chemical reactors, dynamic interactions among process variables might exhibit unexpected responses to control actions when the system is operating in some particular regions. These responses depend on the selection of control and manipulable variables. In this work, a methodology for the evaluation of control strategies is used to identify possible troubles when production objectives and process dynamics are noncompatible. The metho...
