Thermal swing helium purifier and process |
摘要 |
A process and a system for producing helium from a helium-bearing feed gas that is purified in a cryogenic processing unit to produce cryogenic crude helium containing at least 10% helium. The cryogenic crude helium is directly introduced into a thermal swing helium refinery where it is refined. Refrigeration is supplied to the refinery by the cryogenic crude helium from the cryogenic processing unit.
