摘要： Method of, and apparatus (1) for, rejecting nitrogen from a hydrocarbon stream (10) to provide a fuel gas stream (510). A hydrocarbon stream (10) is at least partially liquefied and subsequently expanded. The expanded hydrocarbon stream (110) is fractionated in a fractionation column (150) to provide an nitrogen-rich hydrocarbon stream (160) and a nitrogen-lean hydrocarbon stream (170). The nitrogen-rich hydrocarbon stream (160) is partially condensed in a condenser (200) by cooling against a refrigerant circulated in a dedicated first refrigerant circuit (800), and phase-separated to provide a nitrogen-rejection stream (260) and a nitrogen-lean reflux stream (270) which is returned to the fractionation column (150). The nitrogen-lean hydrocarbon stream (170) is partially vaporized and phase-separated to provide a vapour stream (360) that is returned to the fractionation column (150) and a liquefied nitrogen-lean hydrocarbon stream (370) that is subjected to sub- cooling. The fuel gas stream (510) is generated from the sub-cooled nitrogen-lean hydrocarbon stream (410).

摘要： The present invention relates to a method for the liquefaction of a hydrocarbon-rich stream, preferably a natural gas containing stream, by heat exchanging against a refrigerant (1a-d) . The liquid refrigerant (19) is evaporated using heat from the hydrocarbon-rich stream, thereby obtaining an evaporated refrigerant (3a-d) . The evaporated refrigerant (3a-d) is subsequently compressed (5), cooled (10) against ambient thereby fully condensing the compressed refrigerant. Next, the fully condensed compressed refrigerant (12) is further sub-cooled (14) by indirect heat exchange against an auxiliary refrigerant being cycled in an auxiliary refrigerant. Then the subcooled refrigerant (16) is expanded (18) thereby forming the liquid refrigerant (19).
