Abstract

A krypton-xenon concentration process which also produces substantially rare gas-free oxygen gas [15,42] while requiring a stripping column substantially smaller than is required by conventional process wherein feed liquid [36] is provided directly to a reboiling zone [40] and only the vapor from the reboiling [41] zone is passed through the stripping column
