摘要： 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 to define an annulus column region and an interior core column region. The present annular divided wall column further includes structured packing elements disposed within at least the annulus column region as well as a ring-shaped cantilevered collector; and a ring-shaped distributor disposed in the annulus column region above or below the plurality of structured packing elements. The thermal expansion and contraction of the second annular column wall in a radial direction and in an axial direction is independent of the thermal expansion and contraction of the first annular column wall in the radial and axial directions.

摘要： A wiper band assembly suitable for use in packed distillation columns used in an air separation unit is provided. The wiper band assembly includes specially designed metal or metal alloy wiper tabs that are longer and thinner than conventional wiper tabs. The longer and thinner wiper tabs preferably have a thickness between about 0.05 mm and 0.25 mm and a length greater than about 50.0 mm. The physical dimensions and characteristics of the wiper tabs are selected to avoid permanent deformation during the installation process and provides continuous engagement with the interior surface of the packed column wall when the wiper tabs are exposed to pressure differentials typically seen in such packed distillation columns.
