FIELD: cryogenic equipment, particularly to clean and separate krypton-xenon mixtures obtained in air-separating plants.
SUBSTANCE: method involves cleaning the mixture and separating thereof by rectification operation with the use of compressed refrigerant to be cooled in rectifying column stills, wherein the coolant is taken from cooling cycle and returned in the cycle; additionally cleaning mixture flow, krypton and xenon fraction flows, as well as krypton product and xenon product flows of radionuclide by filtering and/or adsorption and/or rectifying and/or absorption and/or chemical and/or physicochemical methods in additional cleaning devices, which remove radionuclide from the flows and certify the flows and cylinders before cylinder filling with separation products to detect radionuclide content and/or activity. Device for above method realization is also disclosed.
EFFECT: possibility to clean separation product of radionuclide for following product usage in medicine and increased economical efficiency of cleaning and separation operations.
