Summary

This explosion was caused by the failure of a valve bonnet in a high-pressure section of a 60,000 bbl-per-day hydrocracker. A vapor cloud formed from the release, ignited, and was followed by a large fire fed by escaping hydrocarbons at high pressure. The explosion resulted in the collapse of a large section of pipe rack and destruction of a large fin-fan cooler mounted above the rack. Many pumps were destroyed and a separator was badly damaged. Approximately 300 fire fighters and 33 fire trucks participated in the two and a half-hour effort to control the fire. Foam concentrate consumed totalled 3,200 US gallons. The hydrocracker was out of service for 12 months.

[ Property Damage $113 Million. Estimated Current Value $205 Million ]
