HEAVY-WATER PRODUCTION BY H2S-H2O CHEMICAL EXCHANGE PROCESS

摘要

A heavy water production stage in a bithermal H2S gas - H2O liquid exchange plant wherein the cold tower is operated under temperature and pressure conditions such that H2S in the liquid phase is formed and is maintained in the separation units (sieve trays or plates) of the cold tower. It has been found that the presence of liquid H2S acts as an efficient anti-foaming agent.
