Abstract: A packing assembly for a column comprises a cage element which carried a packing element. The packing element comprises a first plurality of parallel plates and a second plurality of parallel plates. The first plurality of parallel plates have peripheries which enable them to be accommodated within a sphere. The second plurality of parallel plates interconnect the first plurality of parallel plates and are positioned normally to the first plurality of parallel plates. The second plurality of parallel plates have peripheries which enable them to also be accommodated within the sphere. The packing element is housed in a spherical cage element which possesses a crush strength sufficient to withstand crushing forces to be encountered when the packing assembly is deployed in a column. The packing element self-orients in the column during use to reduce pressure drop and improve performance during the course of operations.

Abstract: Column packing elements comprise and preferably consist of two individual components, namely a strong and rigid “outside” cage, and an “inside” variable component preferably formed of a monofilament and/or mono-multi-filament fibers, which can be varied to produce a significant increase in surface area of the known art in random packings.
