Claims
- 1. A column packing element comprising a corrugated sheet having a top and a bottom and a plurality of flutes laterally disposed on said sheet, each said flute comprising an elevation with respect to said sheet, the elevation disposed at an angle to said sheet, said elevation angle being 90 degrees or less with respect to an axis from said top to said bottom thereby forming a shelf along the sheet sufficient to cause liquid flowing down the packing element to form a pool on said shelf.
- 2. The column packing element of claim 1 wherein the elevation angle is within the range of from 45 to 85 degrees.
- 3. The column packing element of claim 1 wherein each said flute has a height within the range of from 0.05 to 10.0 millimeters.
- 4. The column packing element of claim 1 wherein each said flute has a length within the range of from 0.5 to 10.0 millimeters.
- 5. The column packing element of claim 1 wherein the flutes comprise sharp angled peaks and troughs.
- 6. The column packing element of claim 1 wherein the flutes comprise curved peaks and troughs.
- 7. The column packing element of claim 1 wherein the flutes comprise flat surfaced peaks and troughs.
- 8. The column packing element of claim 1 wherein the corrugated sheet is made of metal.
- 9. The column packing element of claim 8 wherein the metal is aluminum.
- 10. The column packing element of claim 1 wherein the corrugated sheet contains one or more perforations.
- 11. A method for carrying out mass transfer between vapor and liquid comprising countercurrently passing vapor up and passing liquid down a column containing a plurality of packing elements vertically disposed within said column, said packing elements each comprising a corrugated sheet and a plurality of flutes laterally disposed on said sheet, each said flute comprising an elevation with respect to said sheet, the elevation disposed at an angle of 90 degrees or less with respect to the vertical thereby forming a shelf along the sheet, and forming a pool comprised of downflow in liquid on the shelf.
- 12. The method of claim 11 wherein the vapor and liquid are each comprised of oxygen and nitrogen.
