Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: Instrument Failure

The incident occurred at Motiva's Refinery on 12/19/11 due to an upset of the refinery's fluid catalytic cracking unit (FCCU). The upset began when the FCCU Wet Gas Compressor controller unexpectedly switched to back up and slowed the FCCU Wet Gas Compressor speed down. This over-pressured FCCU Fractionator tower which caused the tower's pressure controller to open the flare. The FCCU Wet Gas Compressor controller was taken out of automatic mode and placed into manual mode and the speed was increased to reduce the FCCU Fractionator tower pressure. The flaring ceased when the pressure reduced on the FCCU Fractionator.
