Accident Classified As:
a control system power failure at the Refinery Gas Compression Unit caused a reduction in compressor capacity due to poor compressor control. As a result of the reduced capacity, the compressors were unable to process all of the refinery gas and the excess gas was routed to the refinery flare syste
This incident was not preventable because the failure of the compressor control system was a result of a failure in both the primary and alternate power supply systems. The back-up power system should have supplied power to the compressor control systemwhen the primary failed to do so because of an electrical malfunction. Remedial Measures - an investigation is ongoing and the appropriate follow-up actions will be completed. Reportable quantities for nitrogen oxide and sulfur dioxide were exceeded.
