Accident Classified As: Below Reportable Quantity (BRQ)
The 210-1513-01 Vacuum Bottoms Pump inboard and outboard motor bearing housings were smoking during routine observations. The 210-1513-02 Vacuum Bottoms Pump (back-up) was already out of service for repairs. The board operator was notified and started reducing Crude charge rate. The 210-1513-01 Vacuum Bottoms pump was shut down due to the outboard motor bearing igniting. The 210 Crude Unit shutdown procedure was initiated. The 210-1801-01 Offgas Compressor tripped due to a high level in the 210-1202 Compressor Suction Drum. Both pumps were already on in automatic. The outsider operator opened the bypass around the flow controller to the Product Receiver. Crude overhead gas was flared in the North Ground Flare. About 5 gallons of crude oil from a flange on the Refinery's Oily Water Sewer and processed in the WWTP.
The root cause analysis will determine whether or not this incident was preventable.
The boardman cut charge rates to Crude Unit 10 and shut down Crude Unit 210. Both Compressor Suction Drum pumps were turned on, and the bypass around the flow controller was opened. The operator increased the suction drum pressure to assist the pumps in pressuring out the level to the startup compressor. The incident investigation will result in recommendation items designed to prevent the recurrence of this event. Initial report states material did go offsite. Verbal report and Hazardous Materials Incident Reporting Form state that H2S was released (and incorrectly reporting that the reportable quantity for it is 500 lbs), while the refinery statement letter reports only SO2.
