Neon Helium Purification System
The Crude Neon and Helium Purification System collects raw gas from the neon and helium enrichment section of the air separation unit. It removes impurities such as hydrogen, nitrogen, oxygen and water vapour through a series of processes: catalytic hydrogen removal, cryogenic nitrogen adsorption, cryogenic neon-helium fraction and helium adsorption for neon separation. This process produces high purity neon and helium gas. The purified gas products are then rewarmed, stabilised in a buffer tank, compressed using a diaphragm compressor and finally filled into high pressure product cylinders.

Oxygen Generator by Pressure Swing Adsorption (PSA)
According to the principle of pressure swing adsorption, the pressure swing adsorption oxygen generator uses the artificially synthesized high quality zeolite molecular sieve as the adsorbent, which is loaded into two adsorption columns, respectively, and adsorbs under pressure and desorbs under depressurized conditions, and the two adsorption columns are in the process of pressurised adsorption and depressurized desorption respectively, and the two adsorbers alternately adsorb and desorb, so as to continuously produce oxygen from the air and supply customers with oxygen of the required pressure and purity.

Air Seperation Unit(ASU)
An Air Separation Unit (ASU) is a device that uses air as feedstock, compressing and super-cooling it to cryogenic temperatures, before separating out oxygen, nitrogen, argon, or other liquid products from the liquid air through rectification. Depending on the user’s needs, the products of the ASU can either be singular (e.g., nitrogen) or multiple (e.g., nitrogen, oxygen, argon). The system can produce either liquid or gas products to meet different customer requirements.
