A LOW-TEMPERATURE PLANT FOR THE PRODUCTION OF HEAVY WATER
A plant for the production of heavy water, which was erected by Sulzer Brothers for Emser Werke AG. at Domat/Ems, Switzerland, is described. The raw material is natural water which first undergoes seven-fold deuterium enrichment in three electrolysis stages. The gaseous mixture of hydrogen and deuterium produced by electrolytic dissociation is cooled to --251 ts C. The liquid then goes to a Kuhn rectifying column, where the exchange processes taking place at 22 ts K result in 400-fold deuterium enrichment. The product of the column is burned with oxygen and then passed to a second Kuhn column in which the D/sub 2/O concentration is brought up to 99.8%. The plant at Ems employs oil-free labyrinth-piston compressors and highspeed expansion turbines for hydrogen. High vacuum is used to insulate all heat exchangers, turbines, and control units. (auth)
