NOVELTY - The method involves discharging a vapor fraction as OFF gas comprising a discharge fraction of an overhead vapor (30) obtained from an overhead space of a nitrogen stripper column (20) and comprising a bypass portion. A portion of a liquid recycle portion is returned to a liquid hydrocarbon product stream (90). The liquid recycle portion is provided with at least portion of an excess liquid. The process is repeated from selectively splitting to discharging steps of bypass portion in vapor fraction of OFF gas, and an internal stripping section (24) is bypassed by bypass portion.    USE - Method of removing nitrogen from cryogenic hydrocarbon composition such as liquefied natural gas (LNG) comprising nitrogen-containing liquid phase and methane-containing liquid phase.    ADVANTAGE - The non-stripping portion is passed through the condenser, so that valuable portions of the process vapor that are split off in the non-stripping portion, such as typically vaporous methane, are lost through the off gas can be avoided and can be re-condensed and added to excess liquid, which is led back ultimately to the liquid hydrocarbon product stream. The provided solution can facilitate the handling of these vapors both during holding mode and loading mode operations in an effective manner. Since the provided solution can allow for selectively stripping of the compressed vapor into stripping and non-stripping portions, it can allow to selectively bypass the stripping section in the nitrogen stripper column with any process vapor in excess of what is needed as stripping vapor. The liquid recycle line can avoid feeding too much liquid onto the rectifying section and can avoid passing the recycle liquid through the rectifying section. Thus the disturbance of the equilibrium in the nitrogen stripper column can be avoided.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for apparatus for removing nitrogen from cryogenic hydrocarbon composition comprising nitrogen-containing liquid phase and methane-containing liquid phase.
