  • Pressurizing with and recovering helium
    Patent number: 5390533
    Abstract: A process and system for pressurizing a vessel for integrity testing with gas comprising helium, recovering the gas comprising helium, and purifying the gas comprising helium for reuse. The process for purifying the gas stream comprising helium comprises drying the gas stream; separating the dried gas stream in a membrane separator stage into a helium-enriched permeate product stream and a helium-depleted raffinate stream; recovering helium in the raffinate stream in a membrane stripper stage thereby producing a purge stream; and purging water from the dryer with the purge stream.
    Type: Grant
    Filed: June 20, 1994
    Date of Patent: February 21, 1995
    Assignee: Praxair Technology Inc.
