    摘要： Process for the purification of an aqueous stream coming from the Fischer-Tropsch reaction which comprises feeding said aqueous stream to one or more pervaporation units obtaining an aqueous stream enriched in oxygenated organic compounds (retentate side) and an aqueous stream enriched in water (permeate side), feeding said aqueous stream enriched in oxygenated organic compounds to a saturator obtaining a gaseous stream leaving the saturator, feeding said gaseous stream to a synthesis gas production plant. Said process allows at least a part of the aqueous stream coming from the Fischer-Tropsch reaction to be used as process water in a synthesis gas production plant, subsequently sent to a Fischer-Tropsch plant for the production of hydrocarbons.
