T I T L EMETHOD FOR HEAVY-WATER PRODUCTION BYH2S-H2O CHEMICAL EXCHANGEPROCESSI N V E N T O RGraeme G. StrathdeeABSTRACT OF DISCLOSUREA heavy water production stage in a bithermalH2S gas - H2O liquid exchange plant wherein the cold toweris operated under temperature and pressure conditions such.that H2S in the liquid phase is formed and is maintained inthe separation units (sieve trays or plates) of the coldtower. It has been found that the presence of liquid H2Sacts as an efficient anti-foaming agent.
