Abstract:
Method for the liquefaction of a hydrocarbon-rich gas stream containing aromatic and heavy hydrocarbons, in particular a natural gas stream, where, prior to the liquefaction, a separation of the aromatic and the heavy hydrocarbons, in particular the C.sub.5+ hydrocarbons, comprisesa) a fraction (9, 11, 14) containing heavy hydrocarbons is admixed to the hydrocarbon-rich gas stream (1) to be liquefied,b) this mixed fraction (1, 2) is supplied to a separator (D),c) a gas fraction (3) freed of aromatic and heavy hydrocarbons is withdrawn from separator (D) and liquefied (E2), andd) a liquid fraction (5) enriched with aromatic and heavy hydrocarbons is withdrawn from separator (D).
