Abstract
Process for the treatment of the aqueous stream coming from the Fischer-Tropsch reaction comprising : feeding the aqueous stream containing the organic by products of the reaction to a distillation or stripping column ; separation from the column of an aqueous stream enriched in alcohols having from 1 to 8 carbon atoms and other possible volatile compounds ; feeding the aqueous stream containing the organic acids leaving the bottom of the distillation column to an ion exchange step wherein said aqueous stream is put in contact with an anionic exchange resin bed and the production of two outgoing aqueous streams : an aqueous stream (i) enriched in organic acids having from 1 to 8 carbon atoms ; a purified aqueous stream (ii) with a low content of organic acids.
