METHOD OF TREATING WATER STREAM FROM FISCHER-TROPSCH REACTION USING ION-EXCHANGE RESIN Russian patent published in 2013 - IPC C02F1/42 C02F1/04 B01D15/04 B01D15/36 C10G2/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of treating water which is formed as a by-product during Fischer-Tropsch synthesis. The method of treating a stream of water from a Fischer-Tropsch reaction involves: feeding a water stream containing organic reaction by-products into a distillation or stripping column; separating from the column a water stream rich in alcohols having 1-6 carbon atoms and other possible volatile compounds; feeding a water stream containing organic acids, coming from the bottom part of the distillation column to an ion exchange step, where said water stream is brought into contact with a layer of an anion-exchange resin, and obtaining two output water streams: a water stream (i) rich in organic acids having 1-6 carbon atoms; a purified water stream (ii) having low content of organic acids.

EFFECT: obtaining water which is purified to the required degree, having minimal content of organic compounds.
