Crude Oil Petroleum Product Classification And Uses

Crude Oil Petroleum Product Classification And Uses is a subject of Petroleum Engineering. Petroleum products are all obtainable components of crude oil fraction which depends on the method of distillation .

These products range from methane to asphalt. They include both hydrocarbon and product containing other elements. The percentage of the elements is given below:

composition Percentage element (%)
carbon 83-87
hydrogen 11-15
nitrogen 0-0.5
sulphur 0-6
oxygen 0-3.5

The Crude Oil Petroleum Product Classification And Uses are summarized as follows:

light components

  • Hydrocarbon between C1-C2 (gas)
  • Liquid petroleum gas (LPG)
  • Gasoline (petrol)
  • Light Naphtha
  • heavy Naphtha

middle components

 

  • Residential heating fuel
  • Kerosene
  • Diesel
  • Other light fuel oil

Heavy products

  • Heavy fuel oil
  • Wax
  • Lubricating oil
  • Asphalt

Others products are known as cake.

Fraction composition Boiling point (˚C)
Naphtha C5H12 –C8H14 30 -150
Petroleum ether   30 -70
Gasoline C6H14 –C8H18 70 -90
Ligroin C6H14 –C8H18 90 -120
Benzene petrol C8H18 –C10H22 120 -160
Kerosene C10H22 –C18H38 160 -300
Gas heavy oil C18H38 –C42H86 Above 300
Residue   Above 400
Paraffin oil    
Lubricating oil    
  • Liquefied petroleum product (LPG): these categories are normally gases. They are length hydrocarbon and are condensed to liquid state. They include: propane, propylene, n-butane, butylenes; with a trace of ethane, ethylene, pentane, pentene. LPGs can also be extracted natural gas.
  • Naphtha: this is found under the temperature of gasoline. It has many components. These components on the used (link) and conversion process. Naphtha can be of hydrocarbon and individual component types. In hydrocarbon types includes; olefins, paraffin, naphthalene and aromatics.
  • Kerosene: this distillate is obtained by straight run distillation. A specified composition of paraffin is required to ensure normal burning. On cracking of kerosene is many hydrocarbon and non hydrocarbon compounds.
  • Lubricating oil: this includes; paraffin, ceresin, petroleum and many more.
  • Miscellaneous petroleum products: it is comprises of greases, bitumen, cake and many more.   Unlock this exclusive content by using one of the sharing buttons below.
