PD-07-110 Integration of Early Fault Detection and Diagnosis In Industrial Processes: FCC Application

Description:

Many approaches have been tested to detect and diagnose faults in complex processes. It has been proposed that a hybrid architecture integrating some of these approaches might lead to a better result. We propose an integration architecture which uses knowledge from the operational and fault states of the process to build a logic program and uses a rigorous dynamic model in order to detect and diagnose the defined faults. Tests using this integration architecture have been made on a Model IV fluid catalytic cracking unit, and the results are presented.
