摘要: A process and associated apparatus for removing aromatics and/or higher molecular weight hydrocarbons from a methane-based gas stream comprising the steps of (a) condensing minor portion thereby producing two-phase stream, (b) feeding said two phase to upper section column, (c) column an aromatic- heavies-depleted (d) lower heavies-rich liquid (e) contacting via indirect heat exchange with methane-rich stripping warmed cooled (f) column; (g) in stream.
