Metal Cascade-mini ring
The
preferential orientation of the packing,
resulting in most of its surface being positioned efficiency. vertically in the
tower rather than horizontally, is also advantageous for mass transfer. It is
very important that as much of the available
surface area as possible be effectively wetted. The underside of any horizontal
surface in the packed bed is shielded from the liquid trickling down and is
therefore not effectively wetted. By definition, these dry surfaces take no
part in the mass transfer process and are lost.packing significantly reduces
this effect,and therefore improves efficiency.
