Cryogenic Nitrogen Gen...
In a cryogenic nitrogen generator (using a dual-column system as an example), air is first drawn in through a series of filtration, compression, precooling, and purification processes. During precooling and purification, moisture, carbon dioxide, and hydrocarbons are removed from the air. The treated air then enters the cold box where it is cooled to liquefaction temperature through a plate heat exchanger before entering the bottom of the lower column. The liquid air at the bottom is super-co...

Neon Helium Purificati...
Our neon-helium purification system is a state-of-the-art refinement system designed to produce pure neon and helium. Based on large scale ASU, the device collects raw material gas from the condensing evaporator of an ASU rectification column before undergoing catalytic reaction, adsorption purification, pressurization, heat exchange and rectification processes. To ensure optimal purity levels are achieved for both gases, our equipment also includes oxygen-adding and hydrogen-removal devices ...

Krypton Extraction Equ...
Rare gases such as krypton and xenon have high value in many applications, but their composition in the air is very low and generally difficult to produce directly. The krypton xenon purification equipment developed by our company is based on a large air separation unit and also uses the principle of cryogenic rectification to transport the raw material LOX containing a very small amount of krypton xenon to the fractionation column for adsorption and rectification through the cryogenic LOX p...

VPSA Oxygenerator
The VPSA oxygen generator produces enriched oxygen from the atmosphere. It works by using a blower to transport filtered air into an adsorber. The special molecular sieve in the adsorber then absorbs the nitrogen components, while oxygen is enriched and discharged as the product. After a period of time, the saturated adsorbent must be desorbed and regenerated under vacuum conditions. To ensure continuous production and oxygen supply, the system will typically include multiple adsorbers, with ...
