ABSTRACT:
A cryogenic rectification system for enhancing the recovery of argon wherein the pressure of the argon column is reduced from that of other columns in the system and a small stripping section is created within the argon column by the use of an additional condenser/reboiler and by the introduction of the argon column feed at an intermediate point of the column.
