Key Terms |
Definition |
Barrel |
A unit of volume equal to 42 U.S. gallons.
|
Distillate Fuel Oil |
A general classification for one of the petroleum fractions produced in conventional
distillation operations. It includes diesel fuels and fuel oils. Products known as No. 1,
No. 2, and No. 4 diesel fuel are used in on-highway diesel engines, such as those in trucks
and automobiles, as well as off-highway engines, such as those in railroad locomotives and
agricultural machinery. Products known as No. 1, No. 2, and No. 4 fuel oils are used primarily
for space heating and electric power generation.
|
Finished Motor Gasoline |
A complex mixture of relatively volatile hydrocarbons with or without small quantities of
additives, blended to form a fuel suitable for use in spark-ignition engines. Motor gasoline,
as defined in ASTM Specification D 4814 or Federal Specification VV-G-1690C, is characterized
as having a boiling range of 122 to 158 degrees Fahrenheit at the 10 percent recovery point to
365 to 374 degrees Fahrenheit at the 90 percent recovery point. Motor Gasoline includes
conventional gasoline; all types of oxygenated gasoline, including gasohol; and
reformulated gasoline, but excludes aviation gasoline. Note: Volumetric data on blending
components, such as oxygenates, are not counted in data on finished motor gasoline until
the blending components are blended into the gasoline. Finished motor gasoline includes
all ethanol blended gasoline (e.g. E10, E85).
|
Jet Fuel |
Includes Kerosene-type (Commercial or Military) and Naphtha-type.
|
Kerosene-Type Jet Fuel |
A kerosene-based product having a maximum distillation temperature of 400 degrees Fahrenheit at
the 10-percent recovery point and a final maximum boiling point of 572 degrees Fahrenheit
and meeting ASTM Specification D 1655 and Military Specifications MIL-T-5624P and MIL-T-83133D
(Grades JP-5 and JP-8). It is used for commercial
and military turbojet and turboprop aircraft engines.
|
Naphtha-Type Jet Fuel |
A fuel in the heavy naphtha boiling range having an average gravity of 52.8 degrees API,
20 to 90 percent distillation temperatures of 290 degrees to 470 degrees Fahrenheit, and
meeting Military Specification MIL-T-5624L (Grade JP-4). It is used primarily for
military turbojet and turboprop aircraft engines because it has a lower freeze point
than other aviation fuels and meets engine requirements at high altitudes and speeds.
|
Other Oils |
Includes aviation gasoline, kerosene, natural gas liquids, LRGs, other hydrocarbons and
oxygenates, aviation gasoline blending components, naphtha and other oils for petrochemical
feedstock use, special naphthas, lube oils, waxes, coke, asphalt, road oil, and miscellaneous oils.
Includes naphtha-type jet fuel beginning in 2004. Propane/propylene were included with
other oils prior to 2004.
|
Petroleum Products |
Petroleum products are obtained from the processing of crude oil (including lease condensate),
natural gas, and other hydrocarbon compounds. Petroleum products include unfinished oils,
liquefied petroleum gases, pentanes plus, aviation gasoline, motor gasoline, naphtha-type jet
fuel, kerosene-type jet fuel, kerosene, distillate fuel oil, residual fuel oil, petrochemical
feedstocks, special naphthas, lubricants, waxes, petroleum coke, asphalt, road oil, still gas,
and miscellaneous products.
|
Products Supplied |
Approximately represents consumption of petroleum products because it measures the
disappearance of these products from primary sources, i.e., refineries, natural gas
processing plants, blending plants, pipelines, and bulk terminals. In general, product
supplied of each product in any given period is computed as follows: field production, plus
refinery production, plus imports, plus unaccounted for crude oil, (plus net receipts when
calculated on a PAD District basis), minus stock change, minus crude oil losses, minus refinery
inputs, minus exports.
|
Propane (C3H8) |
A normally gaseous straight-chain hydrocarbon. It is a colorless paraffinic gas that boils
at a temperature of - 43.67 degrees Fahrenheit. It is extracted from natural gas or refinery
gas streams. It includes all products designated in ASTM Specification D1835 and Gas Processors
Association Specifications for commercial propane and HD-5 propane.
|
Propylene (C3H6) |
An olefinic hydrocarbon recovered from refinery processes or petrochemical processes.
|
Residual Fuel Oil |
A general classification for the heavier oils, known as No. 5 and No. 6 fuel oils, that remain
after the distillate fuel oils and lighter hydrocarbons are distilled away in refinery operations.
It conforms to ASTM Specifications D396 and D975 and Federal Specification VV-F-815C.
No. 5, a residual fuel oil of medium viscosity, is also known as Navy Special and is defined in
Military Specification MIL-F-859E, including Amendment 2 (NATO Symbol F-770). It is used in
steam-powered vessels in government service and inshore powerplants. No. 6 fuel oil includes
Bunker C fuel oil and is used for the production of electric power, space heating, vessel
bunkering, and various industrial purposes.
