Claims16
A random packing element comprising:
- a transfer element, wherein said transfer element has an edge, said edge being configured with a plurality of alternating depressions and extensions having a radius of about 3 millimeters which increase the overall length of said edge.
A method for manufacturing a random packing element comprising:
- providing a sheet having a first side and a second side;
- forming a plurality of protuberances on said first side, wherein said protuberances are formed through punching and have a substantially curved surface for increasing the surface area of said first side;
- cutting a plurality of incisions through said sheet for defining a plurality of transfer element;
- and
- bending said sheet to form a random packing element configuration.
