ABSTRACT:
The argon recovery of an air distillation plant is increased by increasing the argon rectifier reboil and simultaneously decreasing the nitrogen stripping reboil. No additional power and minimal added equipment is required. Referring to FIG. 1, two separate argon rectifier reflux condensers (7 and 9) are provided, either for a single argon rectifier or optionally as shown for two separate argon rectifiers (12 and 13). Kettle liquid is partially evaporated in reflux condenser 7 and the liquid residue is further evaporated in reflux condenser 9 to a vapor of differing (higher) O.sub.2 content. The two vapor stream are separately fed to different heights of column 2, separated by countercurrent contact zone 11.
