A support grid for filling material packing and to a component set for producing such a support grid, including support strips and top strips which are inclined relative to one another in opposite directions. The support strips and top strips intersect one another, the inclination of each top strip is defined by at least one top strip receiving groove which is made in at least one support strip and in which the top strip is received, and the orientation of each support strip is stabilised by at least one support strip receiving groove in which the support strip is received.

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.

A high capacity and high efficiency co-current and cross-flow vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of offset contacting modules in horizontal stages. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor and a demister. Half modules comprise downcomers against the shell of the vessel for transporting liquid to the subjacent stage.

An assembly for supporting a member in a vessel comprises a clip comprising an arm with a first end attached to a panel and a second end opposed to the panel. The panel is secured in the vessel. The assembly also comprises a plate slidably disposed between the second end of the arm and the panel. The subject matter also pertains to the clip itself and the method of use.

A high capacity and high efficiency vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by a half module comprising a downcomer against a shell of a vessel for transporting liquid to a subjacent stage which utilizes a demister to effect vapor-liquid separation at the downcomer outlet.

A clip assembly for holding down a member in a vessel comprising a clip comprising a first panel comprising a tab extending from the first panel and a protrusion extending from the first panel, and a second panel integral with and normal to the first panel for engaging the member. A wall in the vessel comprises a cut-out adapted to receive the tab and a recess disposed laterally to the cut-out and adapted to receive the protrusion upon inserting the tab into the cut-out and sliding the tab in the cut-out laterally with respect to the recess. The subject matter also pertains to the clip itself and the method of use.
