Abstract

<PICT:0979320/C1/1> In the method of concentrating deuterium in natural water using a " cold " tower 1 through which initial water descends in countercurrent to cooled and D-enriched H2S, a portion of the D-enriched H2O so produced flowing via a heatexchanger to a " hot " tower 3 through which D-impoverished reheated and humidified H2S from cold tower 1 is passed upwardly whereby the H2S is enriched in D and thereafter cooled and dried in drier tower 7 by direct contact with an ancillary cooling water circuit before reentry into the cold tower 1, that quantity of D-enriched water which is to be passed to the hot tower 3 is introduced into the ancillary cooling-circuit water stream at the top of drier 7, wherein it assists in the cooling of the Denriched H2S, and an equal quantity of the ancillary cooling-circuit water stream which has been heated by contact with the D-enriched H2S is removed at the bottom of drier 7 and led through a conventional heat exchanger 2 en route to hot tower 3. The admission of the D-enriched water from cold tower 1 into the ancillary cooling circuit water stream reduces the quantity of water that must traverse heat-exchangers 8 and 9, which transfers its heat to an equal quantity of liquid from the circuit including H2S humidifier 6. The remaining quantity of humidifier-circuit liquid is heated in heat-exchanger 11 by hot waste water from stripper 5 and heat exchanger 4, which recover dissolved residual H2S from the effluent liquid from hot tower 3, said H2S being recirculated to the bottom of hot tower 3. In the main H2S circuit, from the top of cold tower 1, D-impoverished H2S passes upwardly in succession through humidifier 6, hot tower 3 wherein the H2S becomes enriched in D, drier-cooler 7, and finally cold tower 1, wherein the H2S becomes impoverished in D by isotopic exchange with the initial water. The method described allows of a reduction in heat exchange surface area for a given consumption of energy.
