Natural Gas Liquefaction Employing Patent 10,620,100 granted 4/14/2020 to Jeffrey M. Lacy, James A. Smith Independent Refrigerant PathA method of liquefying natural gas begins with cooling a gaseous natural gas process stream with a refrigerant Since 2005, INL innovationflowing in a path isolated from the natural gas process has resulted in more thanstream. The refrigerant composition may be selected to enhance efficiency of the refrigerant path and may 560 issued patents. be operated at pressures, temperatures and flow rates differing from those of the natural gas process stream. Other methods of liquefying natural gas are described. A natural gas liquefaction plant is also described.Patent 10,655,911 granted 5/19/2020 to Terry D. Turner, Bruce M. Wilding, Michael G.
