FIELD: chemistry.
SUBSTANCE: method of producing a multicomponent solution of a krypton-xenon mixture and a special purity solvent involves feeding a multicomponent solution into a precursor solution line, preliminary physical-chemical purification from explosive and hardening impurities, cooling and fractional separation in columns. Said columns are equipped with samplers in the concentration part or blow line and the vapour zone of the bottom. A krypton-xenon mixture containing volatile impurities and a stream of a solvent containing volatile impurities are obtained in the column for obtaining a krypton-xenon mixture. The method also includes purifying the stream of the solvent fraction in a column for obtaining special purity solvent from volatile impurities to obtain a special purity solvent. All impurities that are volatile relative to krypton are removed with the stream of the solvent fraction, wherein the part of said impurities which is semi-volatile relative to the solvent is removed in a column for purification from intermediate impurities. An apparatus for carrying out said method is described.
EFFECT: invention reduces content of impurities in a krypton-xenon mixture, simplifies and reduces the cost of processing said mixture.
