ABSTRACT:
A packing element for enhancing contact between a first fluid having a predominant direction of flow and a second fluid comprises a plurality of adjacently disposed layers of material, each of which is disposed generally in a plane aligned with the direction of flow. The layers each include a plurality of rows of fluid-deflecting corrugations that project out of the plane of the layer, and each of the corrugations include a pair of oppositely-inclined surfaces that define an elongated vertex oriented in a diagonal direction with respect to the predominant flow direction. In one configuration, each corrugation is arranged so that its pair of surfaces are at least partially offset from each other along the diagonal direction. In another configuration, the corrugations have two pairs of oppositely-inclined surfaces that define the elongated, diagonal vertex, and the surfaces in each pair are at least partially offset from each other along the diagonal. In a third configuration, the corrugations include: (1) a pair of oppositely-inclined surfaces that define an elongated, diagonal vertex and that are at least partially offset from each other along the diagonal direction, and (2) a pair of oppositely-inclined elements having a different inclination than that of the pair of surfaces, with each element defining at least one opening through which fluid passes.
