Accident Classified As: No Information Given
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.
This release is considered to be not preventable at this time.
The suction drum instrumentation was repaired and the compressor was restarted. The instrumentation causing the compressor trip was repaired in order to prevent recurrence. This letter has been delayed due to Hurricane Katrina. The event is considered as reasonably unforeseeable, and qualifies as an upset. No further action warranted at this time.
