An unexpected shutdown of a flare stack at Lion Oil in El Dorado Tuesday released 820 pounds of sulphur dioxide into the air in 20 minutes, according to a report filed with the National Response Center.
“Sour natural gas went vent through the sour gas flare for 20 minutes due to the unexpected shutdown of the gas processing unit at Lion Oil refinery,” stated the report. “The specific cause has not been determined at the time of this report.”
Great Lakes Chemical Corporation is listed as a suspected responsible party on the report. So far no responses have been elicited from representatives from both companies as to how the release occurred and who is responsible.
UPDATE: A representative from Great Lakes returned my call and is looking into a joint project between the two plants which may be the reason both names are included in the NRC report.
