What are the application areas of air separation equipment?

Air separation equipment is a device commonly used to separate and purify substances based on the principle of selective adsorption and desorption of material molecules or ions to solid or liquid interfaces under laminar flow conditions. The application fields of air separation equipment are very wide, and some common application fields of air separation equipment will be introduced in detail below.

1. Petroleum refining industry: Air separation equipment is widely used in petroleum refining industry in the process of oil separation, methanol purification, ethanol purification, basil ketone separation and so on. Through the use of air separation equipment, various components in the crude oil can be effectively separated and a high purity product can be obtained.

2. Chemical industry: In the chemical industry, air separation equipment can be used for the separation and purification process of organic solvents. For example, by separating the different components of acetic anhydride and cyclohexanone, high purity acetic anhydride and cyclohexanone can be obtained.

3. Pharmaceutical industry: Air separation equipment in the pharmaceutical industry is mainly used for purification and separation of drugs. For example, impurities, impure substances and solvents in drugs can be removed by air separation equipment to obtain high-purity drugs.

4. Food industry: In the food industry, air separation equipment is widely used in the purification and separation of food additives. For example, food additives are separated from food to obtain high-purity additives to ensure the quality and safety of food.

5. Beverage industry: Air separation equipment is often used in the beverage industry for the purification and separation of alcohol, acid, alkali and other substances. Through the use of air separation equipment, harmful substances and impurities in the beverage can be removed and the quality of the beverage can be improved.

6. Pharmaceutical industry: In the pharmaceutical industry, air separation equipment is widely used in the purification, separation and extraction process of drugs. For example, drugs can be purified from plant extracts by air separation equipment to obtain high purity active ingredients.

7. Environmental engineering: In environmental engineering, air separation equipment is used to treat pollutants in wastewater and exhaust gases, as well as to extract and recover useful substances. For example, harmful gases in waste gas can be removed or recycled through air separation equipment to reduce environmental pollution.

8. Energy industry: In the energy industry, air separation equipment is often used for the purification and separation of natural gas and gas. Through air separation equipment, impurities and sulfides in natural gas can be removed, and the quality and utilization efficiency of natural gas can be improved.

9. Metal smelting industry: air separation equipment is widely used in the metal smelting industry for metal extraction and purification process. For example, different metals in copper-bearing ores can be separated by air separation equipment and high purity copper can be obtained.

10. Bioengineering: In bioengineering, air separation equipment is often used for waste liquid treatment and separation of biological products in bioreactors. Through the air separation equipment, the harmful substances in the waste liquid can be removed, and the biological products can be purified and separated.

In short, air separation equipment has a wide range of applications in many industries, from petroleum refining to the pharmaceutical industry, from the food industry to environmental engineering, can play an important role. With the development of science and technology, the application field of air separation equipment will be further expanded to provide more efficient and reliable separation and purification solutions for all walks of life.
