Abstract: The problems and the emergency repair measures of single pipe blockage, wear on cone transition, concentricity deviation, guide cone damage of the third stage cyclone of the regenerator in the FCCU of the No.2 Refinery of PetroChina Fushun Petrochemical Company are introduced. The reasons are analyzed from the aspects of metal content of crude oil, metal content of equilibrium catalyst, physical properties of catalyst, operation parameters and the third stage cyclone body. Trace metal elements, fine powder of catalyst, operation fluctuation, design and installation problems of the third stage cyclone promote the scaling and efficiency reduction of the third stage cyclone. The preventive measures are put forward to ensure the safe and stable operation of the third stage cyclone.

Key words: FCC, the third stage cyclone, analysis
