IMPROVEMENTS IN OR RELATING TO APPARATUS FOR THE PRODUCTION OF DEUTERIUM- ENRICHED HYDROGEN
An apparatus for the production of deuterium-enriched hydrogen is described. The apparatus has low power consumption and is fed with impure hydrogen. The unit consists of a distillation column, a feed heat exchanger in which the hydrogen feed to the distillation column passes countercurrentiy to deuterium-depleted hydrogen leaving the distillation column, and a refrigeration circuit. The refrigeration circuit consists of at least three heat exchangers in which deuterium-depleted hydrogen from the at least two expansion turbines connected between the heat exchangers in the return side of the circuit. The unit also has means whereby a fraction of the deuterium-depleted hydrogen leaving the distillation column and passing countercurrently to the hydrogen feed to the distillation column in the feed heat exchanger is fed to the hottest point of the refrigeration circuit. The feed heat exchanger is provided with flow reversing means for purification of the feed below 50 deg K at the pressure of the distillation column. (N.W.R.)
