Accident Classified As: Reportable Quantity
Cause of Problem: Process Upset
The refinery's natural gas supplier over-pressured the natural gas supply pipeline coming into the plant. This caused a pressure relief valve on the pipeline to active and release the natural gas, and the resulting hissing/whistling noise attracted the attention of operations personnel.
Discharge Preventable - No
The relief valve opened as designed to protect the pipeline from excessive pressure and then automatically closed.
Notes/Remedial Actions
The relief valve automatically closed as designed once the excess pressure relieved.
