Abstract (en)
[origin: WO2010040935A2] The method of the invention includes cooling an inlet stream (72) within an upstream heat exchanger (28). The method includes feeding the cooled inlet stream (76) into a fractioning column (50) and collecting the denitrogenated hydrocarbon stream at the bottom of the column (50). The method includes feeding a nitrogen-rich stream (106) from the head of the column (50) into a disengager (60) and collecting the gaseous head stream from the disengager (60) in order to form the helium-rich stream (20). The liquid stream (110) from the base of the first disengager (60) is separated into a liquid nitrogen stream (18) and into a first reflux stream (114) that is fed as a reflux into the head of the fractioning column (50).
