Abstract
The present invention relates a process and apparatus that recovers a helium rich stream from a mixed gas having low concentrations of helium therein. More specifically, the invention relates to an integrated process and apparatus for treating a mixed feed gas from an operating process that produces a fluid product from natural gas containing helium, such as processes that produce ammonia, methanol, or liquid hydrocarbons.
