Brief Introduction
The packing support at the bottom of the column serves a dual function: 1) It must support the packing in the column, and 2) It must distribute the vapor uniformly into the packing without causing local flooding.
Pro-pak Protruded Metal Distillation Packing with High Surface Area
Detailed Introduction
Pro-Pak is formed from metal ribbon through which more
than 1,000 tiny holes per square inch have been protruded.
As the points of the die push through the metal, jagged
burrs are formed on the back side of the ribbon. ProPak’s unique wetting properties derive from a rectangular
network of capillaries on the surface of the metal, produced
by the combined effect of the holes in the ribbon and the
roughness of the burrs. To observe the wetting action, one
has only to dip a strip of protruded ribbon into a beaker
of liquid hydrocarbon. Almost instantly the liquid crawls
above the submerged portion of the ribbon, wetting both
sides. A colored blotter held against the ribbon one-half
inch above the liquid level can be seen to deepen in color
at once. This self-wetting property ensures that Pro-Pak stays
wet in service in the distillation column and retains its high
efficiency. Because the surface area of the packing remains
effective under low liquid loadings, high column efficiency
is maintained at vapor velocities very much lower than the
flooding velocity.
