Abstract
A structured packing is disclosed. The structured packing has a plurality of packing elements stacked together as 'building blocks' to provide the packing for an exchange column. Each packing element comprises a polyhedron (e.g., a cube) having a plurality of edges formed by elongated rods. At least one transfer sheet is disposed within the polyhedron (e.g., a cube), wherein the first end of each transfer sheet connects to a different edge of the polyhedron and the second end of each transfer sheet connects to another edge of the polyhedron. In one embodiment, the intersection of the transfer sheets forms two pyramids within the cube-shaped packing element, the bases of the pyramids being opposite sides of the cube and the apices of the pyramids intersecting substantially at the center of the cube. In the preferred embodiment, at least one side of each pyramid is open and the other sides of the pyramids formed by the intersecting transfer sheets provide flow surfaces within the packing element. The elements allow great flexibility in the manner and relative orientations in which the elements can be packed together, allowing great design freedom to manufacturers and users of exchange columns.
