PROCESS FOR THE TREATMENT OF THE AQUEOUS STREAM COMING FROM THE FISCHER-TROPSCH REACTION

摘要

The present invention relates to a process for the treatment of the aqueous stream coming from the Fischer- Tropsch reaction, comprising: - feeding the aqueous stream (1) containing organic by- products of the reaction to a distillation or stripping column (10); - collection from the column of a distillate (2) enriched in alcohols having from 1 to 8 carbon atoms and other possible volatile compounds - feeding the aqueous stream leaving the bottom of the column (3) to a reverse osmosis unit (20) and the production of two outgoing streams; - an aqueous stream (4) enriched in organic acids with from 1 to 8 carbon atoms; - a partially purified aqueous stream (5) with a low acid content.
