Title:
KRYPTON AND XENON RECOVERY METHOD
Document Type and Number:
WIPO Patent Application WO/2010/019308
Kind Code:
A3
Abstract:
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.
