METHOD OF WATER CLEANING AT STAGE OF HYDROCARBONS SYNTHESIS DURING GTL PROCESS, AND METHOD OF ITS USE Russian patent published in 2015 - IPC C02F1/16 C02F1/74 C01B3/40 C10G2/00 C02F101/34 C02F103/36 

FIELD: oil and gas industry.

SUBSTANCE: invention can be used during HCs production from natural or associated petroleum gas. Method of oxygenates cleaning from reaction water generated at stage of HCs synthesis from syngas during GTL process includes conversion of even part of the contained oxygenates under conditions of syngas chilling by even part of the reaction water at temperature over 500°C upon contact with catalyst of the oxygenates steam conversion. Further syngas cooling temperature below 400°C is performed by the cleaned water injection in the syngas flow. Method of use of the reaction water generated at stage of HCs synthesis from syngas during GTL process includes its cleaning of the oxygenates under conditions of the syngas chilling at temperature over 500°C upon contact with catalyst of the oxygenates steam conversion, cleaned water degassing. The cleaned degassed water is used to cool the syngas to temperature below 400°C and produce the water steam.

EFFECT: invention ensures effective cleaning of the reaction water of the oxygenates, and use of the produced cleaned water as feed water for boilers and water steam production.
