Abstract: A system and method for reducing a vapor temperature in a packed distillation column. Liquid is collected from a packed section of the packed distillation column in a liquid collector disposed below the packed section. A super-heated vapor is distributed from a vapor feed disposed below the packed section such that the super-heated vapor contacts the liquid of the liquid collector and reduces a temperature of the super-heated vapor.

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 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.

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.

Abstract: A method and apparatus for argon rejection and recovery in which argon is separated from air within a cryogenic air separation plant having a divided wall argon rejection column and condensed using an argon condenser disposed internally within the lower pressure column. The resulting argon stream is subsequently rejected or recovered and optionally purified within an integrated adsorbent based argon refining and purification subsystem to produce product grade argon.

Abstract: 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.

Abstract: A structured packing arrangement for reducing vapor bypass in the gaps between the edges of structured packing elements or bricks and the packed distillation column wall is provided. The structured packing arrangement includes a high pressure drop shroud attached to portions of the perimeter of the structured packing elements and in the gap between the edge of the structured packing elements and the interior surface of the distillation column wall. The high pressure drop shroud urges the ascending vapor flowing at or near the edges of the structured packing elements to stay within the structured packing elements instead of escaping through the side of the structured packing toward the distillation column wall.
