The application of air separation technology makes the preparation of oxygen and nitrogen more convenient

Air separation technology is a technology that uses molecular sieves or liquid separation methods to separate oxygen and nitrogen from air. In the air separation process, the air is first sent to the separation device after compression, cooling and dehumidification treatment. In the separation device, the temperature and pressure are controlled, and the selective adsorption characteristics of the molecular sieve or the liquid separating agent are used to adsorb or agglomerate oxygen and nitrogen respectively, so as to realize the separation of the two.

Air separation technology is widely used in petrochemical, chemical industry, electric power and other fields. In the petrochemical field, air separation technology can be used to produce high-purity oxygen and high-purity nitrogen to meet the needs of cracking furnaces, catalytic cracking and other reaction processes. In the chemical industry, air separation technology is often used to produce high purity oxygen and nitrogen for oxidation reactions, nitrogen protection and other processes. In the power sector, air separation technology can be used to produce high-purity oxygen for oxygen combustion in coal gasification and coal-fired power generation.

The application of air separation technology makes the preparation of oxygen and nitrogen more convenient, can meet the demand for higher purity gas in different fields, and improve production efficiency and product quality. At the same time, air separation technology also has the characteristics of energy saving and environmental protection, reducing energy consumption and environmental pollution, which is of positive significance for promoting sustainable development.
