Accident Classified As: No Information Given

Cause of Problem: Equipment Failure

At 7:52am on 8/23/2005, the LPG compressor, K-9200, tripped on high suction drum level due to a problem with the suction drum instrumentation, causing the fuel system to overpressure to the #2 flare. Nitric oxide was released to the atmosphere through the no.2 flare. An unexpected increase in fuel pressure caused fuel system to divert to the #2 Flare.

Discharge Preventable - No

This release is considered to be not preventable at this time.

Notes/Remedial Actions

The suction drum instrumentation was repaired and the compressor was restarted. The instrumentation causing the compressor trip was repaired in order to prevent recurrence.
