Abstract:
The present invention relates to an improvement to a cryogenic air separation process having an argon sidearm column. The improvement to the process for maximizing argon recovery comprises effectuating the intimate contact of the liquid phase stream and the vapor phase stream in the low pressure column and the argon sidearm column of an integrated multi-column, e.g. three column, cryogenic distillation system by utilizing a structured or ordered packing.
