China Cryogenic Air Separation Unit Suppliers - High-Quality Factory Models KDO, KDN, KDON, KDONAr 50-80000Nm3/h
Product Description
LOX, LIN and LAr refer to liquid oxygen, liquid nitrogen and liquid argon respectively. An air separation unit (ASU) is a facility that produces these gases through a cryogenic air separation process.
In an air separation unit, air is compressed and then cooled to a very low temperature, causing it to liquefy. The liquefied air is then separated into its main components using a distillation column. The process produces high-purity liquid oxygen, liquid nitrogen and liquid argon that can be stored and distributed for a variety of industrial, medical and scientific applications.
Liquid oxygen is used in respiratory support in medical facilities, in industrial processes such as metal cutting and welding, and in the production of chemicals and fuels. Liquid nitrogen is used in food packaging, electronics manufacturing, and as an inert gas for purges and blankets. Liquid argon is used as a shielding gas in welding, metal fabrication, and the production of specialty metals.
Overall, the production of LOX, LIN, and LAr via ASU is critical to meeting the diverse needs of industries and applications that rely on these liquid gases.
