    摘要: A single column process to produce nitrogen at relatively high purity and yield by the cryogenic rectification of air employing multiple defined feeds to the column to allow for increased product removal off the top of the column while avoiding the need to recycle withdrawn nitrogen.

    摘要: A krypton-xenon concentration process which also produces substantially rare gas-free oxygen gas while requiring a stripping column substantially smaller than is required by conventional process wherein feed liquid is provided directly to a reboiling zone and only the vapor from the reboiling zone is passed through the stripping column.
