Abstract

In the production of a substance enriched <PICT:0870036/III/1> with deuterium by exchange of D between the principal substance to be enriched and an auxiliary substance in a different phase in a cascade system of interconnected stages each containing two exchange columns at different temperature through each of which the two substances flow in countercurrent and intermingle so that the principal substance is enriched in one column and impoverisched in the other, a portion of both the principal and auxiliary substances flowing through each stage is withdrawn between the exchange columns and passed to the next succeeding stage and is subsequently returned therefrom. In a modification the portion of auxiliary liquid is fed to, and returned from, the next but one succeeding stage. As shown, auxiliary substance passing through each stage 14, 15, 16, except the last 17 is passed from between the exchange columns to the hot exchange columns 23, 24, 25 of the next stage, while the auxiliary substance from the cold columns 19, 20, 21 is returned to the cold column of the preceding stage. Auxiliary substance is recycled through the first stage. The principal substance (not shown) is withdrawn between the columns and passed to the cold column of the next stage, while it is returned to the cold column from the hot column of that stage. The process may be used for H2O-H2S exchange, when the cold columns are at 30 DEG C., the hot at 160 DEG C., and the pressure 200 atms. H2O is then fed to and withdrawn from the first stage 14 and D-enriched water is withdrawn between columns 21, 25, of last stage 17.
