Separation of ultra high purity helium from natural gas.

Author(s) : KNAEBEL K. S., REINHOLD H.

Summary

A two-stage PSA process has been developed for splitting helium from natural gas. The feed typically contains only 2 to 4% helium, up to 70% nitrogen, and the balance methane and other hydrocarbons. Despite that, the desired helium product purity is typically 99.999%. Because of the scarcity of such natural gas deposits and because of economic incentives, high recovery is very important. A PSA system was developed that achieves both the requisite helium purity and high recovery at moderate pressures.
