Abstract
A mass transfer column is provided with an external shell defining an internal region. Packing elements are positioned within the internal region of the mass transfer column. The packing elements have one or more plates formed from sheet material that has been shaped to form a plurality of corrugations on each side of the plate as a series of peaks separated by valleys. A plurality of apertures are arranged across at least a portion of the plate and a plurality of tangs extend outwardly from the surface of the plate surrounding at least some of the apertures. At least some of the outwardly extending tangs are deformed toward the plate.
Claims29
A packing element for an exchange column comprising:
- at least one plate formed from sheet material shaped to form a plurality of corrugations on each side of the plate as a series of peaks separated by valleys;
- a plurality of apertures arranged across at least a portion of the plate;
- and
- a plurality of tangs extending outwardly from the surface of the plate surrounding at least some of the apertures, wherein at least some of the outwardly extending tangs have been deformed toward the plate.
A method for making a packing element for an exchange column, the method comprising:
- forming a plurality of apertures across at least a portion of a plate formed of sheet material such that at least some of the apertures are surrounded by a plurality of outwardly extending tangs;
- and
- shaping the plate to form a plurality of corrugations on each side of the plate as a series of peaks separated by valleys,
- wherein the shaping of the corrugated plate causes at least some of the plurality of tangs to be deformed toward the plate.
A mass transfer column comprising:
- an external shell defining an open internal region;
- and
- one or more packing elements are positioned within the internal region,
- wherein the one or more of the packing elements comprise at least one plate formed from sheet material that has been shaped to form a plurality of corrugations on each side of the plate as a series of peaks separated by valleys,
- a plurality of apertures arranged across at least a portion of the plate and
- a plurality of tangs extending outwardly from the surface of the plate surrounding at least some of the apertures, wherein at least some of the outwardly extending tangs have been deformed toward the plate.
