Accident Classified As:
Cause of Problem: Process Upset
A bearing failed on the vent gas compressor for the vacuum unit.
Discharge Preventable - No
Notes/Remedial Actions
The bearing failure was not predictiable. The compressor was shut down and a valve to the St. Rose flare was opened to lower and control the seal drum pressure. The compressor was replaced with a spare and the unit was returned to normal operating conditions. The spare will be replaced with the repaired compressor during the next unit outage
