One barrel equals 42 U.S. gallons. Barrel-Mile A unit of measurement of pipeline shipment of product that signifies one barrel moved one mile. Barrels Per Calendar Day (BPCD) The amount of input that can be processed under usual operating conditions. The amount is expressed in terms of capacity during a 24-hour period averaged over an entire year. It incorporates typical rate reductions for planned maintenance and other normal operating activities.

20. Glossary of Common Petroleum Terms Hydrotreater The purpose of this unit is to reduces the sulfur and nitrogen contents of the feedstock and to improve the combustion characteristics of the transportation fuels. In addition to sulfur and nitrogen removal, hydrotreating reduces the amount of aromatic hydrocarbons that can give jet kerosene a poor smoke point and diesel fuel a poor cetane number.

21. Glossary of Common Petroleum Terms Independent Marketer A retail petroleum seller or wholesaler, who is not involved in the refining of petroleum products and therefore must purchase its supply of petroleum products from a refiner or other supplier. Jobber (Brand) Customers who enter into a Product Supply Agreement with MPC in which MPC agrees to supply and the customer agrees to purchase Marathon Branded motor fuels at MPC terminals for use in stations where MPC has given permission to use its name and trademarks.

Used for refinery feedstock and gasoline blending. Octane Number A rating, which is the average of the motor octane and research octane of a fuel sample, used to indicate gasolines anti-knock performance in motor vehicle engines. The higher the octane number, the higher the resistance to engine knock.

PADD Petroleum Allocation for Defense District. A group of five geographic areas in the U.S. used in reference to petroleum distribution, created in 1950 by the Petroleum Administration for Defense. These districts were originally defined during World War II for purposes of administering oil allocation. Products Terminal A facility used primarily for the storage and/or marketing of petroleum products that would generally have a total bulk storage capacity of 50,000 barrels or more. It typically receives petroleum products by tanker, barge or pipeline and serves as a loading facility for trucks to transport products to stores, stations and smaller bulk distribution plants.

24. Glossary of Common Petroleum Terms Proration (Also known as an allocation.) A temporary limit on the amount of product customers can purchase at the terminal, usually based on contracts. Used to protect inventories in time of shortage. Can also refer to a limit on the amount of product that can be shipped on a pipeline during a specific period of time by a supplier. PSI Pounds per square inch. Common measure of pressure. Pump Price The self-serve price, including taxes, posted for either gasoline or diesel fuel at a station or store. RBOB RBOB is the acronym for Reformulated Blendstocks for Oxygen Blending. RBOB combined with ethanol makes what we call RFE (Reformulated gasoline with ethanol).

25. Glossary of Common Petroleum Terms RVP Reid Vapor Pressure. This is the vapor pressure of gasoline under a closed vessel at 100 degrees Fahrenheit. Summer months require a lower RVP so gasoline does not evaporate before it can combust in a gasoline engine. Winter months require a higher RVP so gasoline does not vapor lock before it can combust in a gasoline engine. Rack Refers to the loading area or point of sale from which trucks pick up products at a terminal to transport to other destinations. Rack Pricing Price to branded and unbranded customers for purchases of petroleum products at the terminal, typically with the customer arranging and paying for transportation.

Reformulated Gasoline Gasoline with a different composition from conventional gasoline that reduces air pollutants. Resale The simultaneous purchase and sale of products or crude oil to improve profitability by capturing timing, location and/or grade differentials.

This is the time of year when the Clean Air Act of 1990 requires reduced VOC emissions in gasoline in order to maintain air quality. VRU Vapor Recovery Unit. A VRU captures vapors from empty transport trucks that are pushed out of the truck tank during the loading process. Some units actually recover the vapors, convert them to a liquid state through various means and return the product to a tank within the terminal tank farm. Other units, called vapor combustors, burn the vapors in a flare. WTI West Texas Intermediate crude oil. The WTI spot price of crude is reported from Cushing, Oklahoma.
