SITE OPERATIONS HIGHLY INTEGRATED

• Significant coordination of operations- Monthly Joint Management meetings- Day-to-day operation coordination/optimization- Major mechanical workload coordination- Investment planning and general interest optimization

• Many facilities and services shared- Steam, electric, and natural gas purchasing and supply- Docks- Emergency Response- Security- Business Services (accounting, stores, office services, telephone, purchasing)- Human Resources (labor relations, wage training)- Public Affairs- Law- Health Services

OVERVIEW OF BATON ROUGE REFINERY

• Refinery turns crude into prime products of mogas and diesel

• Four basic steps make up the Refinery process- Distillation- Cracking/Conversion ( mogas, create octane)- Treating (remove impurities)- Blending

• Out of these processes come molecules that can be used as Chemicals feedstock

Gas oil

Residuum (“resid”)

Clean products

Butane and Lighter

Generally refers to petroleum and natural gas liquid products in the 60°F - 430 °F boiling point range

Generally includes heating oil, diesel fuel, kerosene, and jet fuel (220 °F - 750 °F boiling point range)

Petroleum distillate in the 400 °F+ boiling point range

Heaviest oil fraction (left in Pipestill after gasoline and other distillates have been distilled off)

Mogas and heating oilAlso includes similar products which require more refining than heavy fuels

*Mogas final boiling point approximately 430 ° F
