Question: What are the products obtained by fractional distillation of petroleum?

Petroleum can be separated into various types of fuel, by a process called refining, using fractional distillation. 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.

What are the products obtained from fractional distillation of petroleum and their uses?

The crude petroleum oil obtained from oil field, undergoes fractional distillation and a number of products are generated. These products of fractional distillation include, petrol (or gasoline), naptha, kerosene, diesel oil, lubricating oil, fuel oil, grease and wax, and some residue. … It is also used as jet fuel.

What are the products of fractional distillation used for?

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 .

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

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 octane number means?

Octane number, also called Antiknock Rating, measure of the ability of a fuel to resist knocking when ignited in a mixture with air in the cylinder of an internal-combustion engine.

What is the basic principle behind fractional distillation?

The principle of fractional distillation is that different liquids boil at different temperature. The miscible liquids boil at different temperature and evaporate at different temperature. When the mixture is heated, the liquid with lower boiling point boils and turns into vapours.

Which mixtures can be separated by fractional distillation?

Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points.

What is the main difference between simple and fractional distillation?

Simple distillation is the process in which two liquids with a different boiling point can be separated. Fractional distillation can separate the mixture, which has boiling points close to each other.

What is the difference between distillation and fractional distillation?

Distillation: Distillation is a method used to isolate boiling point liquids and consists of gaps of at least 50 degrees. … Fractional distillation is a method used to isolate liquids which boil closer. In order to produce pure components the process must be replicated many times.

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.
