The main function of air separation equipment is to separate gases such as oxygen, nitrogen, argon, etc. from the air to supply them to different production and application fields. These equipment are widely used in industrial production, scientific research, medical treatment, environmental protection and other fields. In industrial production, air separation equipment is used to produce gases such as oxygen, nitrogen, argon, etc., which play an important role in processes such as smelting metals, welding, cutting, oxidation, catalytic reactions, etc. In addition, oxygen is also widely used in medical treatment, water treatment, food processing and other fields, while nitrogen is used in food packaging, chemical industry, pharmaceutical production, etc.
The separation principle of air separation equipment is based on the differences in the physical and chemical properties of different gases. Common separation methods include cryogenic distillation, adsorption separation and permeation separation. Cryogenic distillation is the main method for producing high-purity oxygen, nitrogen, argon and other gases by liquefying air and separating them according to the difference in boiling points of different gases. Adsorption separation uses the different adsorption capacities of different gases on the surface of the adsorbent for separation, while permeation separation uses the different capacities of different gases to pass through the membrane material for separation.
Air separation equipment is widely used in various industries. In industries such as metallurgy, fertilizer, petroleum and coal chemical industry, air separation equipment provides important raw materials; in the electronics industry, high-purity oxygen, nitrogen and argon are used to manufacture semiconductor materials and electronic gases; in medical and physiological research, oxygen and nitrogen are also widely used. In addition, air separation equipment can also produce gases of different purities according to user needs, and achieve the purpose of economical oxygen use through intelligent control.
