Accident Classified As:
Cause of Problem: Equipment Failure
The 891-K-1 Compressor tripped off-line due to a high liquid level inside the first stage suction drum (891-V-15). This was caused by high liquid levels in the fractionator tower's reflux drum (891-V-12) due to coke fines plugging the filters of the L-11 reflux pumps and L-13 Sour Water pumps at an unexpectedly rapid rate. The compressor's suction steam is automatically diverted to the Low Pressure Flare (308F-D-1) during an emergency shutdown of the compressor. Monitoring at the refinery permitter was performed and "there was no offsite impact."
Discharge Preventable - No
Unexpected trip of the Coker Compressor due to high level in the first stage suction drum of the compressor.
Notes/Remedial Actions
The compressor was started and brought online as soon as proper levels could be established in the first stage suction drum. An investigation is in process to determine the cause of the high levels in the first stage suction drum (which caused the compressor to trip).
