Abstract:
A method and apparatus for argon recovery in which an impure argon stream is separated from air within a cryogenic air separation unit having an argon rejection column and a reflux type argon condenser disposed internally within the lower pressure column. An impure argon stream is subsequently recovered from the argon rejection column and purified within an integrated adsorbent based argon refining and purification subsystem to produce product grade argon. The waste stream from the adsorbent based argon refining and purification subsystem is recycled back to the argon rejection column so as to improve the argon recovery.

Claim (Index 28):
The air separation system of  claim 27 , wherein the auxiliary heat exchanger is further configured to subcool the purified argon product stream via indirect heat with a nitrogen rich liquid stream from the distillation column subsystem to produce a purified liquid argon product stream.
