Cause of Problem: Equipment Failure
On December 24th 2013, Shell Chemical's OL5 operations discovered a pressure relief valve opening to the OL5 flare system.
Discharge Preventable - No Information Given
Notes/Remedial Actions
OL-5 operations began working to remove non condensables in an attempt to get the relief valve to close. To close the pressure relief valve and stop the flow to the flare system, operations reduced the pressure upstream of the pressure relief valve, returning the unit to safe, normal operating conditions.
