A process is described for removing heavies and lights from a hydrocarbon-rich feed fraction, preferably from natural gas, wherein the feed fraction (1) is partially condensed (E1, E2), a heavies-rich liquid fraction (8) is rectificatorily (T1) removed (1st removal stage), the resultant, heavies-depleted gas fraction (10) is at least partially condensed (E4) and rectificatorily (T2) separated into a methane-rich liquid fraction (11) and a lights-rich gas fraction (12) (2nd removal stage). According to the invention, the 1st removal stage (T1) and the 2nd removal stage (T2) are thermally decoupled. |
