A method is described for liquefying a hydrocarbon-rich fraction (1, 1') which contains substantially methane, hydrogen and nitrogen. According to the invention, before the liquefaction (V) of the hydrocarbon-rich fraction (1, 1'), the hydrogen (2) is removed (M) by permeation. This removal (M) of the hydrogen (2) by permeation is effected in a single-stage or multistage removal process. |
