Accident Classified As: Reportable Quantity

Cause of Problem: Instrument Failure

On August 5 at approximately 2:17 PM, the ECLA-W cracker compressor shut down due to an unplanned processor card failure in the compressor control circuit. Feed was immediately isolated from all furnaces serviced by the compressor to reduce flaring until the compressor was restarted. This incident is under investigation to determine which component(s) of the processor card failed.

Discharge Preventable - No

The compressor control systems have multiple back-up electronic circuits, so the unplanned shut down was neither expected nor preventable.

Notes/Remedial Actions

Feed was isolated from all furnaces serviced by the compressor to reduce flaring until the compressor was restarted. This incident is under investigation to determine which component(s) of the processor card failed and to provide mitigating actions to prevent this incident from occurring in the future.
