Accident Classified As:
during a startup event there was a release of sulfur dioxide. There was a shutdown of the #3 Sulfur Recovery Unit on 2/26/2007 due to a malfunction in the HCU Recycle Gas Compressor resulting from a faulty governor on the steam turbine lube oil pump. That caused the automatic safety shutdown of the Hydrocracker.
This incident was not preventable because the failure of the governor was not predictable. Remedial Measures - While the governor is subject to the Preventative Maintenance program, the refinery will assemble a team to investigate possibilities fro improving the reliability of the compressor assembly
