ABSTRACT:
This invention relates to an improved process for preparing high purity argon employing a cryogenic adsorptive technique. In the process air is separated into its components and a crude argon feed containing 0.8 mol % oxygen or less and 0.5 mol % nitrogen or less is generated. The crude argon feed is initially subjected to cryogenic adsorption for effecting nitrogen removal and then further subjected to cryogenic adsorption for effecting removal of oxygen. By conducting cryogenic adsorption in this manner, essentially no supplemental refrigeration is required in the cryogenic adsorption steps.
