摘要： The object of the present invention is to provide a stable isotope enrichment device and a stable isotope enrichment method capable of reducing the discharge amount of toxic or combustible substances or substances causing environmental load in the atmosphere and reducing the amount of raw materials used. The present invention provides a stable isotope enrichment device, including: a distillation column group in which a plurality of distillation columns are connected in a cascade; a raw material supply line (30) that supplies a raw material into a first distillation column (1); a product line (31) that withdraws a product from another distillation column located on the secondary side of the first distillation column (1); an isotope-depleted fluid withdraw line (32) that withdraws an isotope-depleted gas or an isotope-depleted liquid from the first distillation column (1) or another distillation column located on the primary side of the one distillation column (1); an isotope exchange reactor (22) at which the isotope-depleted gas or the isotope-depleted liquid is subjected to an isotope exchange reaction, the isotope-depleted gas or the isotope-depleted liquid is regenerated such that the concentration of molecules containing a target stable isotope in the isotope-depleted gas or the isotope-depleted liquid approaches the natural abundance ratio, and an isotope-regenerated gas or an isotope-regenerated liquid is produced; and an isotope-regenerated fluid return line (33) that re-supplies the isotope-regenerated gas or the isotope-regenerated liquid into the first distillation column (1).

摘要： The present invention provides a method for concentrating nitrogen isotope comprising a step for obtaining a final product nitrogen, in which the stable nitrogen isotope, 15N, has been concentrated, by low-temperature distillation of raw material nitrogen containing trace amounts of oxygen and argon with a plurality of distillation columns composed in a cascade arrangement, wherein together with discharging an argon-oxygen mixture from the bottom of the final column and extracting a 15N-concentrated nitrogen fluid from a lower intermediate point of the final column, the flow rate of the argon-oxygen mixture discharged from the bottom of the final column is controlled based on the reading of a thermometer installed below the point where the final product 15N-concentrated nitrogen is extracted, thereby enabling the final product nitrogen to be stably obtained.

摘要： A process for light water detritiation which includes the steps of water distillation for tritium stripping and enriching, followed by chemical conversion of tritium enriched water to elemental hydrogen, and finally by one or more thermal diffusion columns for final tritium enrichment. The combination of process steps takes advantage of water distillation large throughput capability at low tritium concentration with the simplicity of thermal diffusion for small throughput final tritium enrichment. The water distillation front-end and the thermal diffusion back end processes are compatible with any intermediate chemical conversion process such as electrolysis or water gas shift reaction to convert tritiated water to elemental hydrogen.

摘要： The packing elements are formed of lamella or strips which are constructed of reinforced non-self-supporting woven structure. The reinforcement is provided by wires which are disposed on opposite sides of the woven structure and spot welded together. Where the woven structure is corrugated, the transverse wires are disposed in the troughs of the corrugations. Intermediate layers of flat woven structure can be used between corrugated layers in forming the packing elements.

摘要： The present application discloses a device for multistage continuous preparation of deuterium depleted water, which includes a feeding pump, a plurality of stages of separation systems connected in series, and a receiver, all of which are connected in sequence. Each stage of separation system comprises a distillation column, a vapor-liquid separator, a low-pressure steam compressor, a stream delivery pump, a three-way valve, and a stream output pipe. The present application further discloses a method for preparing deuterium depleted water, wherein natural water is fed into the device of the present disclosure, and the liquid phase stream continuously flows backwards stage by stage under the combined action of the low-pressure steam compressors and the stream delivery pumps. In a single-stage system, the deuterium is deprived depending on the difference in vapor pressure between 1H2O and 2H2O (and/or 1H2HO), and finally, the deuterium depleted water is produced.
