摘要:
A liquid phase catalytic exchange column with a catalyst is configured to receive hydrogen gas. The system uses the catalyst to exchange the hydrogen gas with the tritiated source yielding HT gas and tritiated water. The system monitors tritium content of the tritiated water. When a predetermined tritium level is detected, the tritiated water is released. The system also includes a gaseous permeation system comprising a permeable barrier for the selective extraction of gases.

This invention relates to a method for separation of isotopes, that is, to obtain isotopically pure fractions by separating natural occurring isotope mixtures in elements, where hydrogen is employed as ligand on the elements that are to be isotopically separated, and where the resulting compounds are gaseous at practical temperatures and pressures. More specific, the invention relates to a method for obtaining an isotopically pure 28SiH4 in industrial scale by separating the isotopes in a chromatographic column.

The invention concerns a method for purifying, and concentrating into a minor constituent, a gaseous mixture, a method for detecting said constituent, and an installation for implementing said method. Said method comprises successively a selective permeation of the gaseous mixture through a specific membrane, a purifying step and a concentrating step. The treated gaseous mixture is atmospheric air whereof it is sought to concentrate some of the rare gases in particular xenon and the natural and radioactive species of xenon. The invention combined with nuclear spectrometry is therefore useful for detecting said species, whereof there is very little in the atmosphere, and for monitoring the environment of nuclear stations.

A process is described for the permseparation of gases, isotopes, and liquids by permselective membranes which comprise the use of membranes of solid materials with pores having a size, shape and length resulting in a microcapillary action which causes microphase separation on the molecular level of one component of the fluid, i.e. the component with the highest throughput, and the transport of that component across the membrane by flowing through the pores resulting in a complete or substantially complete separation; said permseparation depends on the difference between the bulk properties of the components. The observations leading to the present invention such as large separation factors between hydrogen and helium, and hydrogen and air, and permseparation of butanol and water as well as special and general procedures of how to carry out the present invention which relates to all areas of science and technology concerning the separation by membranes are described. This also include improved methods of producing nuclepore microfilters.
摘要:
Die Erfindung bezieht sich auf die Verwendung einer Vorrichtung zur Abtrennung und Anreicherung eines Wasserstoffisotops aus einem gasförmigen Wasserstoffisotopengemisch. Außer daß die Abtrennung und Anreicherung der Wasserstoffisotope auf wirtschaftliche Weise möglich sein soll, liegt der Erfindung auch die Aufgabe zugrunde, die Verdichtung der abgetrennten Isotope oder des angereicherten Isotopengemischs ohne zusätzliche Vorrichtungen zu ermöglichen. Die gemäß der Erfindung verwendete Vorrichtung besteht im wesentlichen aus zwei, jeweils allseits verschließbaren und mit Zu- und Ableitungen versehenen Kammern (2, 5), welche eine gemeinsame, bevorzugt für atomaren Wasserstoff permeable Wandung (3) aufweisen. In einer der beiden Kammern ist eine Einrichtung (4) zur Umwandlung von molekularem Wasserstoff in atomaren Wasserstoff angeordnet. In der zweiten Kammer wird der durch die Wand gelangte Wasserstoff in molekularer Form gesammelt. Die Erfindung bezieht sich ferner auf eine Einrichtung für den vorgenannten Verwendungszweck, wobei die Einrichtung aus mehreren kaskadenförmig hintereinander geschalteten Vorrichtungen der vorgenannten Art besteht.
