Petroleum products are materials derived from crude oil (

oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures.[1] Most petroleum is converted into petroleum products, which include several classes of fuels.[2]

According to the composition of the crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. The largest share of oil products is used as "energy carriers", i.e. various grades of

hydrocracking and hydrodesulfurization.

Specialty and by-products

Oil refineries will blend various feedstocks, mix appropriate additives, provide short-term storage, and prepare for bulk loading to trucks, barges, product ships, and railcars.[4]

  • Gasses like propane and methane are stored within petroleum.
  • Liquid fuels blending (producing automotive and aviation grades of gasoline,
    pipeline inspection gauges
    ("pigs").
  • Lubricants (produces light machine oils, motor oils, and greases, adding viscosity stabilizers as required), usually shipped in bulk to an offsite packaging plant.
  • Paraffin wax, used in illumination (candle wax) and other uses. May be shipped in bulk to a site to prepare as packaged blocks.
  • Slack wax, a raw refinery output comprising a mixture of oil and wax used as a precursor for scale wax and paraffin wax and as-is in non-food products such as wax emulsions, construction board, matches, candles, rust protection, and vapour barriers.
  • organosulfur compounds
    .
  • Bulk tar shipping for offsite unit packaging for use in tar-and-gravel roofing or similar uses.
  • Asphalt, used as a binder for gravel to form asphalt concrete, which is used for paving roads, lots, etc. An asphalt unit prepares bulk asphalt for shipment.
  • Petroleum coke, used in specialty carbon products such as certain types of electrodes, or as solid fuel.
  • Petrochemicals or petrochemical feedstocks such as ethylene,

Petroleum by-products

Over 6,000 items are made from petroleum waste by-products, including:

amino acids.[5]
