Application of molecular distillation instrument in petrochemical industry
With the continuous progress of science and technology, the technology of the petrochemical industry is also constantly innovating. Among them, molecular distillation instrument, as an advanced separation technology, has been widely used in the petrochemical industry. This article will introduce the principle, characteristics and application of molecular distillation instrument in the petrochemical industry.
1. The principle and characteristics of the molecular distillation instrument.
Molecular distillation is a separation technique based on the difference in forces between the molecules of different substances. In the process of molecular distillation, the substances to be separated undergo a series of physical and chemical changes at temperatures well below their boiling point. The molecular distillation instrument has the following characteristics:
1.High separation efficiency: Molecular distillation separates according to the difference in the force between the molecules of different substances, and has a high separation efficiency.
2.Low energy consumption: Since molecular distillation is carried out at a temperature well below the boiling point of the substance, it consumes less energy.
3.Environmentally friendly: The molecular distillation process does not involve chemical reactions, so it is environmentally friendly.
4.Wide range of applications: Molecular distillation is suitable for the separation of different types of substances, including high boiling points, heat sensitivity, and high viscosity substances.
Second, the application of molecular distillation instrument in the petrochemical industry.
The petrochemical industry is one of the important application areas of molecular distillation instruments. Here are some specific applications:
1.Separation of petroleum fractions: petroleum fractions contain a variety of components with different boiling points, which can be efficiently separated by molecular distillation technology to obtain high-purity components. These components can be used in the production of fuels, lubricants, petrochemical feedstocks, etc.
2.Waste oil regeneration: Waste oil contains a variety of impurities and water, which can be removed through molecular distillation technology to realize the recycling of waste oil. This can not only reduce the pollution to the environment, but also save costs for the enterprise.
3.Lubricating oil refining: Lubricating oil will be affected by a variety of factors in the process of production and use, resulting in oxidation, polymerization and other reactions, resulting in a decline in oil quality. These deterioration products can be removed by molecular distillation technology, improving the quality and stability of the lubricant.
4.Fuel oil desulfurization: Sulfides in fuel oil are one of the important causes of air pollution. Molecular distillation technology can remove sulfides from fuel oil and reduce environmental pollution.
5.Paraffin oil cracking: Paraffin oil cracking is an important technology in the petrochemical industry, which can produce a large number of organic raw materials such as ethylene and propylene. Molecular distillation technology can play a role in efficient separation in the process of paraffin oil cracking to improve the purity and yield of the product.
6.Coal tar separation: Coal tar is a complex mixture with a variety of components. Molecular distillation technology can be used to separate them to obtain high-purity components, which are used in the production of fuels, chemicals, etc.
7.Waste gas treatment: The waste gas produced by petrochemical enterprises contains a variety of harmful substances, such as sulfides, nitrogen oxides, etc. The use of molecular distillation technology can purify the exhaust gas and reduce the pollution to the environment.
To sum up, molecular distillation instruments have a wide range of application prospects in the petrochemical industry. With the continuous progress of technology and the expansion of application fields, it is believed that molecular distillation instrument will play a more important role in the petrochemical industry in the future.
