    摘要： A structured packing element for a column for at least one of mass transfer and heat exchange between a heavy fluid phase and a light fluid phase. The structured packing element comprises at least two layers of a grid comprising openings that are surrounded and separated from each other by separating elements. At least two of the layers are arranged in a longitudinal direction parallel and in touching contact with each other such that an open space extending from one end to an opposite end of the layers is provided between the layers such that at least one of the heavy fluid phase and the light fluid phase may flow therethrough. An average width of at least 50% of the separating elements between adjacent openings is at least 15 times a layer material thickness and is between 70% and 125% of an average hydraulic diameter of the adjacent openings.

    摘要： A cross-corrugated structured packing element is provided for use in mass transfer or heat exchange columns. The packing element has a plurality of packing layers positioned in an upright, parallel relationship to each other and including corrugations formed of alternating peaks and valleys and corrugation sidewalls extending between the peaks and valleys. The packing element also includes a plurality of apertures each presenting an open area. The apertures are distributed such that the corrugation sidewalls have a greater density of open areas than any density of the open areas that may be present in the peaks and valleys. Some of the apertures may be present in the peaks and the valleys to facilitate liquid distribution. The apertures may also be placed in rows or other patterns that are aligned in a direction along a longitudinal length of the corrugations. Regions with a larger apex radius may be formed in the peaks, such as by depressing spaced-apart segments of the peaks to form spacers in the undepressed portions of the peaks. Some of the apertures may be positioned in the transitions from the depressed portions of the peaks to the unmodified apex sections.
