Liquid Air Separation Equipment for High-Purity Gas Production
Mar 04 , 2026Industrial gas consumption is increasing globally. That is why advanced separation technologies are required. Liquid air separation equipment allows users to produce pure oxygen, nitrogen, argon. Also, continuous supply on an industrial scale is made possible. Users need purity and reliability, which cryogenic separation can provide.
Nanjing Bangwin Gas supplies industrial projects around the world with professional air separation systems. This allows our customers to run operations with consistent gas supply and efficiency maximized.

Liquid air separation equipment cools atmospheric air down to cryogenic temperatures to separate it into its primary components. The equipment liquefies air, then separates the gases through fractional distillation.
Systems are usually installed as part of a cryogenic air separation unit. Liquid air separation equipment is best used for large capacity gas manufacturing.
Air separation is made using a series of exact steps.
l Air Compression
Air is fed into compressors at atmospheric pressure. The system then raises it to a higher pressure and moves it towards filters.
l Air Purification
Particles such as dust, moisture, and carbon dioxide are filtered out. Preventing them from freezing or contaminating the system.
l Cryogenic Cooling
Further, purified air runs through heat exchangers. Lowering the temperature of the air to cryogenic levels until it liquifies.
l Fractional Distillation
The liquid air is sent to distillation columns. Where oxygen, nitrogen, and argon are separated by their boiling points.
l Product Storage
Individually compressed gases are stored and turned into liquid or gas products. Through storage tanks and vaporizers.
