Robustness Improvement in Operating the Reactor - Regenerator
Group for the Catalytic Cracking Unit Using Advanced Automation

Abstract:

This paper presents the researches and the results obtained by the authors regarding the advanced automation of the reactor-regenerator group for the catalytic cracking unit. In this context an advanced control structure is proposed, which is implemented with feedback controllers based on the PID (Proportional - Integrator - Derivate) algorithm. The first part of the paper describes the reactor-regenerator group of the catalytic cracking unit and the associated conventional control structure. Afterwords, the paper presents the authors’ proposed advanced control structure for the reactor-regenerator group. The last part highlights the results of the tests performed by the advanced control based on PID controllers. The simulation results show a robust functioning of the proposed control structure when the conditions for stationary and dynamic regime are met. Keywords: fluid catalytic cracking, advanced control, PID algorithm, dynamic simulator
