摘要： A method for purifying a minority constituent and concentrating it in a majority constituent of a gas mixture that also contains one or more other minority constituent(s) employs (i) a selective permeation step, (ii) next, a purification step, and (iii) finally a concentration step. In the selective permeation step, an initial gas mixture is passed through a membrane to yield a gas mixture that is enriched in the first minority constituent. In the purifying step, the first minority constituent is absorbed by a solid adsorbent which has a strong affinity for the first minority constituent, then following an elution step, a gas mixture that contains essentially only the majority constituent and the first minority constituent is formed. Finally, in the concentrating step, one or more successive adsorption and elution operations on a solid adsorbent, which has a strong specific affinity for the first minority constituent, are employed until an end gas mixture having the desired concentration of the majority constituent and the first minority constituent is obtained. This end gas mixture is highly enriched in the first minority constituent relative to the initial gas mixture. The procedure is particularly suited for detecting rare gases, e.g., xenon, and especially for detecting the natural and radioactive species in the atmosphere. The procedure can be employed in association with nuclear spectrometry to detect and monitor the presence of trace gases in the environment around nuclear installations.

摘要： The present invention is a bi-thermal membrane process for separating and recovering hydrogen isotopes from a fluid containing hydrogen isotopes, such as water and hydrogen gas. The process in accordance with the present invention provides counter-current cold and hot streams of the fluid separated with a thermally insulating and chemically transparent proton exchange membrane (PEM). The two streams exchange hydrogen isotopes through the membrane: the heavier isotopes migrate into the cold stream, while the lighter isotopes migrate into the hot stream. The heavy and light isotopes are continuously withdrawn from the cold and hot streams respectively.

摘要： An apparatus and method for separating oxides of heavy isotopes of hydrogen (deuterium oxide, oxides of tritium and mixed isotope oxides) from light water (H2O) which is contaminated with these heavy hydrogen isotopes such as that currently being discharged in cooling water from nuclear power plants. A central aspect of this invention includes a plurality or bundle of elongated hollow core fibers which are positioned within an elongated enclosed housing having a feed water inlet, an exit stream outlet, and a permeate outlet. At least a portion of the hollow core fibers are at least partially filled or packed with small beads which are comprised of a porous exchange resin carrying waters of hydration. Porosity is controlled by the degree of cross-linking and bead diameter of the exchange resin which is preferably combined with aluminum sulfate or ammonium hydride to form (RSO.sub.3).sub.3 Al or RSO.sub.3 NH.sub.4. By passing the contaminated water through the bead-filled hollow core fibers within the housing, significant amounts of the oxides of heavy hydrogen isotopes remain in the hollow core fiber either combined with the resin beads or collected against the inside wall surfaces of the hollow core fibers. Some of the H2O in the contaminated water permeates out of the hollow core fibers for discharge from the permeate outlet. The water which discharges from the exit stream outlet is substantially lower in heavy hydrogen isotope content. Regeneration of the apparatus is also shown.

摘要： Apparatus for separating the gaseous hydrogen isotopes protium, deuterium and tritium from a gas stream containing one or a plurality of the hydrogen isotopes. A membrane is provided which is permeable to the hydrogen isotopes and impermeable to the gas stream. The membrane has a side facing away from the gas stream and a side exposed to the gas stream. On the side of the membrane facing away from the gas stream, there is disposed a getter which takes up the hydrogen isotopes by absorption at a predetermined absorption temperature and releases the absorbed hydrogen isotopes again by desorption at a desorption temperature above the absorption temperature. The membrane permeable to the hydrogen isotopes covers a surface of the getter so that the getter, at the absorption temperature, absorbs hydrogen isotopes exclusively through the membrane. The membrane and getter constitute an absorption element and are permanently connected to one another.

摘要： A gaseous diffusion enrichment modular unit and gaseous diffusion enrichment plant, comprehending a gaseous diffusion enrichment unit of the enrichment cascade type, being an integrated module containing all the elements of the unit, with several flows of circulation with different enrichment degrees, comprehending an axial compressor in simultaneous work of compression of said flows, a diffuser with membranes. The diffused (enriched) fluid passes through to the compressor in another section to accomplish the following enrichment phase and the non-diffused flow outlet is connected to an injector to even the pressures and to recycle the depleted material. Said modular unit of isotopic enrichment integrates multiple enrichment phases to achieve a high separative efficiency by means of the internal recirculation of a fraction of the diffused fluid in each phase. The multiflow axial compressor is driven by a gas turbine and the outgoing gases of the turbine and the heat generated in the process are injected in a thermal cycle. In the center of the unit is a probe to perform non-destructive analysis. The gaseous diffusion enrichment plant comprehends said enrichment modular units connected in series and the numbers of the phases of one or more said units are different. An application of the present invention is its use for the isotopic separation of uranium hexafluoride in gaseous phase.
