On January 2, 2014 during startup operations of the HCLA unit at the Baton Rouge Refinery, a secondary hydrogen compressor was started to increase the amount of reserve quench available prior to introducing oil into the second reactor. After the secondary compressor was put into service, the unit operating pressure increased significantly and exceeded the specifications of the unit pressure control valves as a result of excess gas from the secondary compressor. The compressor was immediately shut down, decreasing the overall unit pressure.
Immediately upon the unit pressure increase, the secondary hydrogen compressor was shutdown. To prevent recurrence, the operating procedure has been modified to include details regarding a secondary hydrogen compressor operation.
