    During a purge steam to main tower our drum vibrated. We are using a regular procedure about steam flow. The unique difference is the feed. We were processing VR (vaccum residue) mixed with 20 % of slurry oil (decanted oil) from FCCU.
    Any suggestion about this problems ?

    Are you saying 20% of your feed is FCCU slurry?  That seems really high.  We have a standing rule of 10% max and we’ve never gone that high.

    I’d like to know what’s the typical value for vibration on coke drums operations during the complete cycle. Could anyone help me with these typical values?
