Production of heavy water in France; Production d'eau lourde en France

Abstract

Four processes which can be employed on there own or in combination with others, are at present being studied and tried out in France, 1) Process of exchange between H{sub 2}S and H{sub 2}O. A certain amount of laboratory research has been carried out. Also a study of corrosion and operation has been carried out in pilot plants at the same time as the process investigation. 2) Process involving the catalytic exchange H{sub 2}-H{sub 2}O. Studies of liquid phase catalysts are being carried out. 3) The liquid hydrogen distillation process. It has been necessary to resolve numerous theoretical and technological questions. The pilot plant at Toulouse, designed to treat 4000 Nm{sup 3}/h of synthesis gas will soon start production. 4) Process involving the catalytic exchange NH{sub 3}-H{sub 2}. A certain number of investigations have been carried out: the separation coefficient, catalysts, reaction kinetics. The process is promising. The development of a very accurate mass spectrograph has contributed to the success of this work.

Un certain nombre de recherches de laboratoire ont ete faites. Par ailleurs, des pilotes ont permis d'etudier les problemes de corrosion et de fonctionnement, en meme temps que des etudes de procede ont ete realisees. 2) Procede d'echange catalytique H{sub 2}-H{sub 2}O. Des etudes de catalyseurs en phase liquide se poursuivent. 3) Procede par distillation de H{sub 2} liquide. II y a eu a resoudre de nombreux problemes theoriques ou technologiques. L'usine Pilote de Toulouse, prevue pour traiter 4000 Nm{sup 3}/h de gaz de synthese, doit prochainement entrer dans la phase de production. 4) Procede d'echange catalytique NH{sub 3}-H{sub 2}. Un certain nombre d'etudes sont entreprises: coefficients de separation, catalyseurs, cinetique de reaction. Le procede est prometteur. La mise au point d'un spectrometre de masse tres precis a contribue au succes des etudes. (auteur)}
