Abstract:
An annular divided wall column for the cryogenic rectification of air or constituents of air is provided. The annular divided wall column includes a first annular column wall and a second annular column wall disposed within the first annular column wall and radially spaced therefrom to define an annulus column region as the space between the first annular column wall and the second annular column wall. An interior core column region is also defined by the interior space of the second annular column wall. The present annular divided wall column further includes a plurality of packing elements, plurality of trays or a heat exchange device disposed within the interior core column region; and a plurality of packing elements disposed within the annulus column region.

Claim (Index 1):
An annular column for cryogenic rectification of air or constituents of air, said column comprising:\n a first annular column wall; a second annular column wall radially spaced from the first annular column wall and disposed within a first interior space of the first annular column wall to define an annulus column region between the first annular column wall and the second annular column wall and to define an interior core column region as part or all of a second interior space of the second annular column wall; a plurality of structured packing elements of a first type disposed within the annulus column region; and a plurality of structured packing elements of a second type disposed within the interior core column region; wherein the first type of structured packing elements and the second type of structured packing elements have different densities or different geometries.
