KRYPTON AND XENON RECOVERY METHOD |
摘要 |
A method of separating air in which a superheated air stream is introduced into a mass transfer contacting zone associated with a higher pressure column of an air separation unit. Krypton and xenon is washed from a superheated air stream introduced into the mass transfer contacting zone, thereby to form a krypton and xenon-rich liquid. The krypton and xenon-rich liquid is stripped within a stripping column to produce a krypton-xenon-rich bottoms liquid. A krypton-xenon-rich stream composed of the krypton-xenon-rich bottoms liquid from the stripping column is produced for purposes of further refinement. |
