Abstract (en)
[origin: WO2006072390A1] The invention relates to a method for separating a fraction rich in C<SUB>2+</SUB> from liquefied natural gas (LNG), comprising the following steps: a) partial evaporation (E1, E2) of the liquefied natural gas (1, 1'); b) separation (D1) of the partially evaporated natural gas (2) into a first gas fraction (4) rich in C<SUB>1</SUB> and a first liquid fraction (3) rich in C<SUB>2+</SUB>; c) rectifying separation (T) of the first liquid fraction (3) rich in C<SUB>2+</SUB> into a second gas fraction (8) rich in C<SUB>1</SUB> and a second liquid fraction (10) rich in C<SUB>2+</SUB>; d) re-liquefaction (E1) of the first gas fraction (4) rich in C<SUB>1</SUB> and e) feeding of at least one sub-stream (6) of the re-liquefied gas fraction (5) rich in C<SUB>1</SUB> as a return flow to the rectifying separation (T) stage.
