Oil refinery

An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.

Crude oil is separated into fractions by fractional distillation. The fractions at the top of the distillation column have lower boiling points than the fractions at the bottom. The heavy bottom fractions are often cracked into lighter, more useful products. 


Gas (also known as liquified petroleum gas (LPG))

Naphtha

Gasoline (also known as petrol)

Kerosene (also known as jet aircraft fuels)
Diesel
Lubricating oil
Heavy gas oil
Residual (examples are asphalt and tar)

How does a company go about finding oil and pumping it from the ground?

In 2008 alone, the United States produced an estimated 4.9 million barrels of crude oil per day and imported 9.8 million barrels per day from other countries. This oil gets refined intogasoline, kerosene, heating oil and other products. To keep up with our consumption, oil companies must constantly look for new sources of petroleum, as well as improve the production of existing wells.
