  • Mixed refrigerants in LNG cascade
    Patent number: 12111102
    Abstract: Methods and systems for liquefying natural gas using environmentally-friendly low combustibility refrigerants are provided. Methods of liquefaction include cooling a fluid in an LNG facility via indirect heat exchange with an environmentally-friendly low combustibility refrigerants that are propane, ethane and methane mixed with small amounts of fluorinated olefin, but still within close proximity to the boiling points of the pure refrigerants such that the mixed refrigerants can still be used in an optimized cascade process.
    Type: Grant
    Filed: November 11, 2022
    Date of Patent: October 8, 2024
    Assignee: CONOCOPHILLIPS COMPANY
    Inventors: Paul Davies, James Lee Harris, Jr., Emery Jay Thomas, Gregg Sapp
  • Low global-warming refrigerants in LNG processing
    Patent number: 11885561
    Abstract: Methods and systems for liquefying natural gas using environmentally-friendly low combustibility refrigerants are provided. Methods of liquefaction include cooling a fluid in an LNG facility via indirect heat exchange with an environmentally-friendly low combustibility refrigerant selected from the group consisting of: a fluorinated olefin, xenon, any derivative thereof, and any combination thereof.

  • USE OF ALTERNATE REFRIGERANTS IN OPTIMIZED CASCADE PROCESS
    Publication number: 20140150492
    Abstract: Methods and systems for liquefying natural gas using nonflammable refrigerants are provided. Methods of liquefaction include cooling a natural gas stream via indirect heat exchange with a first nonflammable refrigerant selected from the group consisting of: difluoromethane, pentafluoromethane, trifluoromethane, hexafluoroethane, tetrafluoroethane, pentafluorethane, trifluoroethane, pentafluoroethane, any derivative thereof, and any combination thereof during a first refrigeration cycle; and cooling the natural gas stream via indirect heat exchange with a second refrigerant during a second refrigeration cycle.
