METHOD OF PURIFICATION OF WATER FLOW, OUTPUT AFTER FISHER-TROPSCH REACTION Russian patent published in 2014 - IPC C02F9/08 C02F1/04 C02F1/06 C02F101/32 C02F103/36 

FIELD: chemistry.

SUBSTANCE: invention can be used in technology of performing Fischer-Tropsch reaction in industry. Method of purification of water flow, output after Fischer-Tropsch reaction, includes processing with inorganic base, with pKa higher or equal 6.5, and its supply into evaporator; two output flows are obtained p flow of vapour from head part of evaporator and water flow from lower part of evaporator. Flow of vapour is condensed, and water flow is supplied into distillation column. Organic base with pKa higher or equal 7, is added into water flow, output from head part of column, with combination of it with water flow, obtained after vapour flow condensation. Obtained combined water flow is supplied into saturator, into which technologic gas is supplied. Formed gaseous flow, output from head part of saturator, is supplied into installation for obtaining synthesis-gas.

EFFECT: method makes it possible to use, at least, part of flow, output after Fischer-Tropsch reaction, as technologic water in installation for obtaining synthesis-gas, further supplied into Fischer-Tropsch installation for obtaining hydrocarbons.
