The Cause Analysis of Damage and Improvement Measures of Reforming Regenerator Inner Net
This paper summarizes the damage and maintenance of the regenerator inner net in 1#reforming unit of a petrochemical enterprise.The main reasons for the inner net damage of the regenerator are the local overtemperature of the bed caused by the mismatch between the carbon-burning capacity of the regeneration system and the scale of the reaction system,frequent failure of the program control valve,large amount of dust in the system,and unrepresentative thermocouple detection.According to the causes of damage,adding flexible thermocouple,reduceing the failure rate of program control valve and changing the valve with"no stop"are proposed.The application results show that all measures can significantly reduce the risk of local overtemperature of the bed,prevent the damage of the inner net,and significantly improve the operation stability of the 1#reforming regeneration system.
