    摘要： A process and apparatus for separating a fraction rich in C2+ from liquefied natural gas (LNG) is disclosed. In an embodiment, partial evaporation of the liquefied natural gas occurs in a heat exchanger. The partially evaporated natural gas is separated into a first gas fraction rich in C1 and a first liquid fraction rich in C2+. In a separation column, rectification separation of the first liquid fraction rich in C2+ into a second gas fraction rich in C1 and a second liquid fraction rich in C2+ occurs. The first gas fraction rich in C1 is re-liquefied in the heat exchanger. At least one sub-stream of the re-liquefied gas fraction rich in C1 is fed as a reflux to the rectification separation.

    摘要： A process for the separation of C.sub.2+ hydrocarbons from natural gas under pressure wherein the natural gas is cooled (2, 6), partially condensed, and separated (9) into a liquid fraction and a gaseous fraction. The liquid fraction (10) is subcooled (11) and then expanded into the upper zone of a rectifying column (7). The gaseous fraction (23), after engine expansion (25), is also introduced into the rectifying column (7). During rectification, a product stream (37) containing essentially C.sub.2+ hydrocarbons and a residual gas stream (22) containing predominantly lower-boiling components are obtained. The residual gas stream (22) is initially heated by heat exchange (11) with the liquid fraction (10) and then heated by heat exchange (21) with the gaseous fraction obtained after partial condensation. The residual gas stream is then further heated (6, 2) by heat exchange with the feed stream of natural gas to be partially condensed. The heated residual gas is then engine expanded (28) and reheated again by heat exchange with the feed stream of natural gas to be partially condensed (2).
