摘要： A method of natural gas liquefaction comprising first and second nitrogen refrigerant streams, each stream undergoing a cycle of compression, cooling, expansion and heating, during which the first nitrogen stream is expanded to a first, intermediate pressure and the second nitrogen stream is expanded to a second, lower pressure, and the heating occurs in one or more heat exchangers in which at least one of the expanded nitrogen streams is in heat exchanging relationship with natural gas, wherein, in at least one of said one or more heat exchangers, the first and second expanded nitrogen streams are in a heat exchanging relationship with the natural gas and both the first and second compressed nitrogen streams. The liquefaction can occur in three stages: in an initial stage the heated, expanded first nitrogen stream and the heated, expanded second nitrogen stream are used to cool the natural gas; in an intermediate stage the compressed first nitrogen stream is expanded to an intermediate pressure and used to cool the natural gas; and in a final stage the compressed, second nitrogen stream is expanded to a low pressure and used to cool the natural gas.

摘要： A fluid distribution element for transporting heating or cooling fluid to or from a series of heat exchanger channels, said element comprising; at least one port extending through the element in a first direction; at least one localised distribution cavity shaped so as to allow said series of heat exchanger channels to open into said cavity and spaced apart from the port in a second direction perpendicular to the first direction; and at least one passageway connecting the port to the localised distribution cavity such that fluid passing through said port can be transported through said passageway into said cavity for localised distribution to said series of heat exchanger channels, the passageway being narrower than the port and the cavity in a third direction perpendicular to said first and second directions. By aligning a number of fluid distribution elements in the first direction, the ports define a header through the stacked assembly, each port having an associated localised distribution cavity for supplying a series of heat exchanger channels with fluid.
