A high molecular weight gas was routed to the flare gas management system, which prevented the compressor from being able to pump the gas and caused the flare to open.

Discharge Preventable - No Information Given

Notes/Remedial Actions

To stop the discharge, feed rate to the unit was reduced, reducing pressure, and eventually ending the release. A representative from Chalmette Refining contacted LDEQ Emergency Response on 4/4/12 when an all-clear was called, also providing the total release quantity of sulfur dioxide. No fire, injuries, or fatalities resulted from this incident
