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.
