摘要：
Helium is recovered from gas streams containing high concentrations of hydrogen gas and low concentrations of helium gas, such as from the recycle stream from the production of ammonia. The inventive process provides for an integrated process for the recovery of both an enriched helium gas stream product and a high purity hydrogen gas stream product.
