Abstract: The invention relates to cryogenic engineering, in particular to purifying krypton-xenon mixture and is usable in the chemical and oil-and-gas industries. The inventive method comprises purifying and separating the mixture in rectification columns, wherein coolant is removed and returned to a cooling cycle, additionally removing radionuclides from krypton and xenon fractions and from krypton and xenon production flows by means of filtration and/or adsorption and/or rectification and/or absorption and/or chemical and/or physicochemical methods in apparatuses for additional removing radionuclides. Balloons for reception of the separated products are certified with respect to radionuclides content and/or activity prior to and after the filling thereof.

Abstract: The claimed method and apparatus relate to cryogenic technology, particularly to purifying and separating by distillation a target heavy component concentrate thereby obtaining target components, e.g., krypton and xenon, and isotopes of light gases such as deuterium, tritium, helium-3. The method includes temperature-stabilizing a target heavy component concentrate flow, a low-boiling target component fraction flow, and a high-boiling target component fraction flow, irradiating the flows with ionizing radiation thereby obtaining light gas isotopes, purifying the flows, concentrating the light gas isotopes in the flows with subsequently extracting thereof, purifying the production flows from nuclides, using xenon as the high-boiling target component of the concentrate and using krypton as the low-boiling target component of the concentrate. The claimed apparatus can be used for implementing the method.
