Accident Classified As: Reportable Quantity
Approximately 121 pounds of 1,3-Butadiene was released from the BELA-5 unit after a compressor tripped, causing an unplanned shutdown. The compressor trip was caused by a significant fouling incident on both parallel feed filters. The unit's solvent balance was disrupted when the filters fouled, and the compressor tripped due to a high suction drum level.
Material was routed to the flare per design. The unit was shutdown and multiple filters were cleaned.
