The structure of cryogenic air separation unit
Air filtration system: The main equipment includes self-cleaning air filters, which are used to filter mechanical impurities in the air to ensure the quality of air entering the subsequent system.
Air compression system: The system pre-compresses the air through steam turbines, superchargers, air compressors and other equipment to increase the pressure of the air and provide conditions for the subsequent cooling and separation process.
Air pre-cooling and purification system: including air cooling towers, water cooling towers, molecular sieve purifiers and other equipment. The air cooling tower and water cooling tower use chilled water and cooling water to preliminarily cool the compressed air and remove impurities such as moisture and carbon dioxide. The molecular sieve purifier further adsorbs moisture, CO2, acetylene and other hydrocarbons in the air to make the air purer.
Heat exchange system: It mainly includes equipment such as main heat exchangers and subcoolers, which are used for heat exchange during the air separation process to improve separation efficiency.
Distillation system: This is the core part of the cryogenic air separation unit, mainly composed of distillation towers (including upper towers and lower towers), condenser evaporators and other equipment. The distillation tower controls the temperature and pressure to gradually separate gases with different boiling points at different heights.
Product delivery system: including pressure regulating stations, metering stations and other equipment, used to deliver separated oxygen, nitrogen and other products to the device for subsequent use.
Liquid storage backup system: including liquid storage tanks, gas storage tanks, liquid evaporators and other equipment, used to store and vaporize separated liquid oxygen, liquid nitrogen and other products.
