METHOD OF PRODUCING WATER WITH LOW CONTENT OF DEUTERIUM Russian patent published in 2014 - IPC B01D59/40 C01B4/00 C02F1/461 

FIELD: chemistry.

SUBSTANCE: method involves electrolysis of distilled water in an electrolysis cell to obtain deuterium-impoverished hydrogen on a gas-diffusion hydrogen cathode of the electrolysis cell, drying the obtained electrolysis gases, feeding the dried gases into a catalytic isotope exchange column to enrich hydrogen with deuterium and impoverish hydrogen with steam by feeding steam into the column from a steam generator which is supplied with distilled water from a feeder. The deuterium-rich hydrogen is fed by counterflow with steam for further ionisation, and the steam-impoverished hydrogen is fed into a condenser for steam condensation and further mineralisation of the deuterium-impoverished water.

EFFECT: efficient separation of hydrogen isotopes, obtaining a product of higher quality and low cost of the process.
