An ordered packing comprising elongated elements having lengthwise extending surfaces configured to be wet by a liquid phase to thereby form a film thereon. The elongated elements are packed together into a structure such that in each of a plurality of parallel planes, extending in two orthogonal directions, the elongated elements cross one another to form lattices having openings defined between the crossings of the elements. The elongated elements are interleaved within the structure such that elongated elements pass through the openings in the lattices and form repeating clusters of four of the elongated elements in a pyramid-like arrangement. Each of the clusters of the elongated elements and their lengthwise extending surfaces provide pathways for the film to descend through the structure. The structure has an open area for a vapor phase to ascend through the structure and contact the liquid phase.
