Distillation is a common separation technology, which is widely used in chemical, chemical and petrochemical fields. So what is the principle of distillation?
The principle of
distillation can be summarized as "distillation-condensation-separation" three processes. Specifically, distillation is controlled by heating the sample to the boiling point, so that it is evaporated into a gas, and then the gas is cooled into a liquid through a condenser equipped with cooling water, and finally the liquid is separated through a separator. This allows separation of the mixture.

specifically, when the mixture is heated to the boiling point, each of the substances has a different boiling point, so they will evaporate at different temperatures. When the condenser cools the gas, different components in the gas have different boiling points (volatility) and will change from the gas state to the liquid state at different temperatures, that is, they will adhere to the surface of the condenser. The function of the separator is to finally extract different boiling point substances with a purity of up to 99.9%.

In the field of chemistry, distillation is widely used to separate, purify and purify different chemical substances. For example, purification of organic compounds, preparation of laboratory reagents, separation of water and alcohol mixtures, etc.; in the chemical industry, the use of different boiling point components to separate gas, separate crude oil, separate low-value products, etc.; in the petrochemical industry, distillation is mainly used in the separation of fractions, such as processing oil into different grades of petroleum products.

distillation, as an important separation technology, has brought convenience to our production and life. It is necessary to master the principle and application of distillation, and also has a good market prospect. Manufacturers can produce and sell all kinds of distillation equipment to meet the needs of various industries. Students can understand the principle of distillation, help them better understand the chemical knowledge, improve the experimental ability. In addition, this paper also introduces the application of distillation in the fields of chemistry, chemical industry and petrochemical industry, so that we can have a deeper understanding of distillation technology.
