摘要: Process for purifying a gas (1) rich in hydrocarbons and comprising at least 10 ppm by volume of having six carbon atoms, the following steps: Step a) Cooling said to temperature between -20°C -60°C heat exchange with one coolant (3) exchanger (2); b) Scrubbing compounds containing atoms from partially liquefied step washing column (5) overhead (8) its highest end bottom (7) lowest order form, as (8), stream (9) less than 5 and, bottoms (7), liquid (6) enriched five atoms; c) At partial condensation resulting (10, 2) form two-phase (15); d) Separating (15) phase separator pot (16) -80°C (17) (18) (16); e) Use reflux; f) Condensation (20, below -100°C (21) atoms.
