Method of concentrating kryptonxenon

Claim 1

A METHOD OF CONCENTRATING KRYPTON AND XENON IN OXYGEN COMPRISING WARMING A CRUDE KRYPTON-XENON STREAM CONTAINING OXYGEN, HYDROCARBONS, KRYPTON, XENON ARGON AND NITROGEN, PASSING SAID WARMED, CRUDE KRYPTONXENON STREAM THROUGH A CATALYTIC FURNACE REACTOR WHEREIN SAID HYDROCARBONS ARE CONVERTED TO CO2 AND H2O TO FORM A DESENSITIZED, CRUDE, KRYPTON-XENON STREAM REMOVING THE H2O AND CO2 FROMED IN SAID FURNACES FROM SAID DESENSITIZED STREAM, COOLING SAID DESENSITIZED STREAM BY HEAT EXCHANGE WITH A RELATIVELY COLD NITROGEN VAPOR STREAM, DELIVERING SAID COOLED, DESENSITIZED KRYPTON-XENON STREAM TO A RECTIFICATION COLUMN WHEREIN SAID DESENSITIZED STREAM IS SEPARATED INTO A GASEOUS FRACTION SUBSTANTIALLY FREE OF KRYPTON AND XENON WHICH IS REMOVED AT THE TOP OF SAID COLUMN AND A SUBSTANTIALLY PURE KRYPTONXENON-OXYGEN LIQUID FRACTION WHICH IS COLLECTED AT THE BOTTOM OF SAID COLUMN, CONDENSING VAPOR TO PRODUCE LIQUID REFLUX AT THE TOP OF SAID COLUMN BY INDIRECT HEAT
