    摘要: A process is described for the pretreatment of a pressurized natural gas which is saturated with water and contains hydrocarbons and hydrogen sulfide (H.sub.2 S) from a producing well. At least a portion of the natural gas (1) is brought into contact with at least a portion of recycled liquid condensate (2) in a cyclone (5). The vapor phase (6), containing H.sub.2 S and hydrocarbons, is cooled in zone (20), condensed and separated in separator (3). A gas (30) which is enriched in methane and depleted in H.sub.2 S is recovered while the condensate (8) is recycled to cyclone (5) after preheating if necessary. A water-containing liquid effluent (7) which is enriched in H.sub.2 S and depleted in hydrocarbons is recovered from the bottom of cyclone (5). This is reintroduced into the well (10).
