Abstract

An object of the present invention is to provide a method for concentrating oxygen isotopes that is capable of using a small amount of liquid without regularly replenishing a large amount of nitric oxide as a raw material when distilling a large amount of nitric oxide as a raw material. NO tower storage capacity to concentrate oxygen isotopes without reducing the separation efficiency of oxygen isotopes. Oxygen isotopes are obtained by chemically exchanging water obtained by adding hydrogen to oxygen in which the oxygen isotopes generated by the first distillation unit (11) are roughly concentrated and nitric oxide discharged from the second distillation unit (12). Nitric oxide with increased concentration and water with decreased oxygen isotope concentration are supplied to the second distillation device (12) with increased oxygen isotope concentration of nitric oxide, and oxygen obtained by electrolyzing the water with decreased oxygen isotope concentration is refluxed into the first distillation unit (11).

Description

technical field

[0001] The present invention relates to a method for concentrating oxygen isotopes capable of concentrating a large amount of specific oxygen isotopes by distilling nitric oxide in a small amount without periodically replenishing a large amount of nitric oxide as a raw material. The storage capacity of the liquid NO tower can be used to concentrate the oxygen isotope without reducing the separation efficiency of the oxygen isotope.

[0002] this application claims priority based on Japanese Patent Application No. 2012-230766 for which it applied to Japan on October 18, 2012, and uses the content here. Background technique

[0003] In the past, as the oxygen isotope ( 17 O or 18 (O) is concentrated using the distillation method using nitric oxide (NO) as a raw material (hereinafter referred to as "NO distillation method") described in Non-Patent Document 1, distilling water (H 2 O) Distillation method (hereinafter referred to as "water distillation method")...
