Frequent question: Which is obtained as a fraction in fractional distillation of petroleum?

Petrol, Diesel and Kerosene are all products (or fractions) of the process of refining Petroleum. On an industrial scale, the different fractions of Petroleum are separated out by fractional distillation. The Petroleum is heated up, and the gas produced enters the fractionating column.

What are the fractions obtained by fractional distillation of petroleum write two uses of each of them?

Fractional distillation is used in oil refineries (Figure 5.41) to separate the complex mixture into fractions that contain similar boiling points and therefore similar molecular weights and properties. Gasoline, diesel fuel, kerosene, and jet fuel are some of the different fractions produced by an oil refinery.

Which is not obtained as a fraction in fractional distillation of petroleum?

So, Coal gas is not prepared using fractional distillation.

What are the major products of fractional distillation of petroleum?

The products obtained from the fractional distillation of petroleum is Petrol (or gasoline), naptha, kerosene, diesel oil, lubricating oil, fuel oil, grease wax, and some residue.

What is meant by fractional distillation of petroleum?

Fractional distillation separates a mixture into a number of different parts, called fractions. A tall fractionating column is fitted above the mixture, with several condensers coming off at different heights. … The crude oil is evaporated and its vapours condense at different temperatures in the fractionating column.

Which of the following is used in fractional distillation?

Fractional distillation is used in oil refineries (Figure 5.41) to separate the complex mixture into fractions that contain similar boiling points and therefore similar molecular weights and properties. Gasoline, diesel fuel, kerosene, and jet fuel are some of the different fractions produced by an oil refinery.

What are the steps of fractional distillation?

Fractional Distillation Process

  1. Evaporation. Crude oil is heated until it evaporates. Crude oil vapour is put into a fractionating column at the bottom and rises upwards.
  2. Condensation. The temperature is highest at the bottom of the column. …
  3. Collection. The fractions are collected.

Which one is not a fraction of petroleum?

The correct answer is B.

Why do we use fractional distillation?

Fractional distillation is used to separate crude oil into simpler, more useful mixtures . This method can be used because different hydrocarbons have different boiling points .
