Cause of Problem: Process Upset
The facility reported the Coker unit was water quenching the coke material in Cooke Drum PV-918 and encountered a problem with an automated water quench sequence.
Discharge Preventable - No Information Given
Notes/Remedial Actions
The facility took the problematic water quench sequence out of automatic mode and and manually closed off on the water control valve. Once the pressure was reduced to normal operation, the quench cycle was completed. The sequence has been adjusted, and additional orders have been given to the Coker operators so that this activity is consistent on each work shift.
