Catalytic feed oil nozzle issues
Thread Content
Does the feed nozzle for the catalytic cracking reaction crude oil need to be replaced every year during maintenance? (Lately, during annual maintenance, we replace all nozzles in use, regardless of their condition, using the LYCS model.)
If it’s not broken, there’s no need to replace it; if it is broken, send it back to the factory for repair.
The value of repairing nozzles is not high; the repair costs are around 75% of the cost of a new nozzle. When removing an old nozzle, only the wear on its tip can be checked – an internal inspection is not possible. It is recommended to replace the nozzle every two years.
