  • Treatment of nitrogen-rich natural gas streams
    Patent number: 10215488
    Abstract: Helium can be recovered from nitrogen-rich natural gas at high pressure with low helium loss by cryogenic distillation of the natural gas after pre-treatment of the gas to remove incompatible impurities and then recovery of natural gas liquid (NGL) from the pre-treated gas by distillation. Overall power consumption may be reduced, particularly if the feed to the helium recovery column system is at least substantially condensed by indirect heat exchange against a first portion of nitrogen-enriched bottoms liquid at first pressure, and a second portion of nitrogen-enriched bottoms liquid at a second pressure that is different from the first pressure.
    Type: Grant
    Filed: February 11, 2016
    Date of Patent: February 26, 2019
    Assignee: Air Products and Chemicals, Inc.

  • Recovery Of Helium From Nitrogen-Rich Streams
    Publication number: 20190041128
    Abstract: Overall power consumption in a cryogenic distillation process for recovering helium from nitrogen-rich gases comprising helium may be reduced if the feed to the distillation column system is at least substantially condensed by indirect heat exchange against a first bottoms liquid at first pressure, and a second bottoms liquid at a second pressure that is different from the first pressure.
