Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: Process Upset

Reformer Compressor shutdown due to electric failure.

Discharge Preventable - No

The use of the flare system to control the process upset was not preventable because the compressor shutdown was not planned. The flare gas recovery system was overwhelmed by the volume of process gas sent to the system and flaring to safely control emissions was necessary.

Notes/Remedial Actions

Process upset was routed to the flare for release control. Operations safely shutdown the reformer unit and switched downstream unit to pipeline hydrogen.
