zheka24 [161]

Answer:

Fractional distillation

Explanation:

Crude oil, also known as petroleum, is a naturally occurring substance found in the Earth's crust. It is a mixture of different useful substances. These substances are separated from one another based on their individual boiling points in a process called FRACTIONAL DISTILLATION.

The process of fractional distillation entails the application of heat to the crude oil. The different fractions evaporate and condense in the fractionating column depending on their boiling point. The hydrocarbon substances separated are called fractions, and they include bitumen, diesel, kerosene, gasoline, natural gas etc. Therefore, before we can use gasoline (petrol) in our cars, the crude oil needs to be separated into separate products like plastics and ink. This process is called FRACTIONAL DISTILLATION.
