  • LNG integration with cryogenic unit
    Patent number: 10612842
    Abstract: A method for the production of liquefied natural gas (LNG) using a cold fluid provided from a cryogenic unit, such as an air separation unit or nitrogen liquefier, is provided. The method may include the steps of: withdrawing a nitrogen stream from a cryogenic unit, wherein the nitrogen stream is at a temperature between about ?155° C. to about ?193° C.; and liquefying a natural gas stream in a natural gas liquefaction unit using the nitrogen stream from the cryogenic unit.
    Type: Grant
    Filed: November 16, 2017
    Date of Patent: April 7, 2020

  • METHOD FOR RECOVERING GASEOUS NITROGEN FROM THE WASTE NITROGEN STREAM OF AN AIR SEPARATION UNIT
    Publication number: 20180017321
    Abstract: The method for the production of nitrogen can include the steps of a) providing a waste nitrogen gas stream at a first pressure called low pressure, wherein the waste nitrogen gas originates from a low pressure column of a cryogenic air separation unit; b)compressing the waste nitrogen gas stream to a second pressure in a waste nitrogen compressor to produce a pressurized nitrogen stream; and c) introducing the pressurized nitrogen stream to a nitrogen generator under conditions effective for producing a purified nitrogen product, wherein the purified nitrogen product has a higher concentration of nitrogen as compared to the pressurized nitrogen stream.
