      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.

      You are right. Our feed has 20 % of slurry oil from FCC.

      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?
