On May 31, 2013, the Baton Rouge Refinery PHLA unit experienced an atmospheric safety valve lift on the T-1 overhead safety valve. This event was due to an unanticipated power outage experienced at the Baton Rouge Refinery causing shutdown of the C-600A hydrogen compressor. Pressure was returned to normal operating conditions and the block valve below the safety valve was closed to reset the valve. The compressor was then returned to service. Approximately 1,496 pounds of flammable vapor were released as a result of this event.
