摘要： PROBLEM TO BE SOLVED: To recover the rare gas from the mixture gas containing oxygen and at least one kind of rare gas selected from a group of krypton and xenon. SOLUTION: Krypton and/or xenon is separated crudely by a process of rectifying and separating the mixture raw material in a rare gas recovery system to obtain rare gas-lean gaseous oxygen (GOX), and rare gas-enriched product. The process is characterized in that at least about 50 mole % of the mixture in gas phase is fed to the gas recovery system, and in the case of separating by selectively adsorbing the mixture raw material, xenon concentration in the mixture raw material is set to 50 times or less than the xenon concentration in air. As one advantage of a preferred embodiment is that, it can easily be led into an air separating device of an existing pump transport type liquid-oxygen cycle for addition.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for recovering krypton and/or xenon. SOLUTION: Krypton and/or xenon is separated crudely from a mixture including oxygen and at least one rare gas selected from a group composed of krypton and xenon in a method including steps for feeding the mixture or a mixture derived therefrom to a rare gas recovery system, and separating the mixture material in the rare gas recovery system into rare gas-lean gaseous oxygen (GOX) and rare gas-enriched product. In the method, at least about 50 mol% of the mixture is fed to the rare gas recovery system in a gaseous phase provided that, when the mixture material is separated by selective adsorption, the concentration of xenon in the mixture material is no greater than 50 times the concentration of xenon in air. One advantage of a preferred embodiment is that it can easily be retrofitted to an existing pumped-liquid oxygen cycle air separator. COPYRIGHT: (C)2010,JPO&INPIT
