A Stepwise Diagnosis Method for the Catalyst Loss Fault of the Cyclone Separator in FCC Units

The catalyst loss is one of the main faults that affects long-term run an FCC unit. Most faults, namely excessive emissions catalyst, are closely related to cyclone separators. separator usually caused by abnormal changes in some aspects, such as operational conditions and equipment performance integrity, which directly gas–solid separating operation separation performance. This paper firstly summarized various involving Next, characteristics factors industrial operations were extracted analyzed. Then, a stepwise diagnosis approach was proposed determine causes location separator. Finally, case introduced detail prove effectiveness method based on sampled data from commercial It hopeful provide practical for elimination fault
