Accident Classified As: Reportable Quantity
Operational issues at the Marathon Refinery caused them to send off-specification dry gas, high in hydrogen sulfide, to Shell Chemical's GO-1 Process Unit.
The incident was not preventable by Motiva Enterprises, LLC.
Flaring was not continuous throughout the start and end dates. A portion of the off specification dry-gas from the Marathon Refinery was flared at the Motiva West Operations Ground Flare to prevent contamination of downstream catalysts and an operational at GO-1 with potential for subsequent flaring. The West Ops Ground Flare is owned and operated by Motiva Enterprises, LLC. SCOGI Louisiana Holdings LLC and Shell Chemicals LP are the owner and operator, respectively, of the GO-1 Process Unit. Marathon is the supplier of dry gas to Shell Chemical.
