GOODLOE® Tower Packing
provides the highest mass transfer efficiency of any commercially
available packing. GOODLOE packing
can generate HETP (height equivalent to a theoretical plate)
values as low as 2-3 inches (50-75 mm) in pilot columns, and
values of 4-10 inches (100-250 mm) in production columns. These
high efficiencies are possible because of the high ratio of
surface area-to-volume inherent in the GOODLOE packing design.
GOODLOE packing is produced by knitting multiple fine metallic
filaments that are then crimped and either spiral wound or
folded and layered into elements for insertion into the tower.
The open structure that results creates multiple twisting paths
for the vapor to travel while providing a high void fraction
that minimizes pressure drop. At the same time, the inherent
capillary action of the fine wires causes the liquid to spread
into thin films that continuously combine and divide for optimum
mixing and contact with the vapor throughout the entire packing
volume. The resilient properties of the packing construction
assure firm contact with the tower wall, minimizing the possibility
of vapor bypassing or liquid channeling. The net result is
a packing with very high mass transfer efficiency and low pressure
drop.
GOODLOE tower packing is manufactured in several different
styles depending on efficiency and pressure drop requirements.
It is available in all 300 and 400 series SS, Alloys 200, 400,
600, 800, and so forth, Alloy 20, aluminum, copper, nickel,
phosphor bronze, tantalum, and titanium.
