Air Separation Unit Manufacturers

Cryogenic air separation technology is the most mature and widely used basic process in the field of industrial gas separation today. It can produce oxygen, nitrogen and argon on a large scale and efficient basis. As a key industrial equipment, the cryogenic air separation equipment achieves a stable supply of ultra-high purity gas by liquefaction and distillation by using the differences in boiling points of each component. As a leading air separation unit manufacturers, we are committed to providing customers with safe, reliable and efficient large-scale air separation devices to meet the continuous demand for a large number of gas resources in core industrial fields such as metallurgy, chemical industry, and new energy.

Core technology and working principle

Our cryogenic air separation equipment is based on the classic low-temperature distillation principle, and its process flow is precise and efficient:

1. Air compression and purification: After the ambient air is removed by the filter, it is compressed by the main air compressor to the required pressure, and then enters the molecular sieve purification system to completely remove impurities such as moisture, carbon dioxide and hydrocarbons, and provide clean raw materials for cryogenic air separation.

2. Heat exchange and cooling: The purified air is heat exchanged with the refluxed low-temperature product gas in the main heat exchanger and is cooled to close to the liquefaction temperature.

3. Distillation separation: Liquefied air enters the fractionation column system. In the high-pressure tower (lower tower) and the low-pressure tower (upper tower), multiple partial vaporization and partial condensation are performed using the different boiling points of oxygen, nitrogen and argon components (oxygen-183°C, nitrogen-196°C). Finally, high-purity nitrogen is obtained at the top of the tower, high-purity oxygen is obtained in the tower kettle, and high-purity argon can be extracted from it.

4. Product output and storage: After the separated gas product is reheated to ambient temperature through the main heat exchanger, it is output as a pipe gas or sent to the liquefied storage system.
