Abstract
Distillation, absorption, and gas
stripping have traditionally been
performed in tall columns utilizing trays
or packing. Columns perform
satisfactorily, but have characteristics
which may be disadvantages in some
applications: Large size, particularly
height; high weight; high cost of
installation; difficulty in modularization;
foaming for certain systems; must
be vertical, especially for trayed towers;
large liquid inventory; difficulty in
modifying column internals once installed;
start up time to reach steady state
conditions in excessive.
Many of these disadvantages can be
overcome by use of HIGEE, an innovative
vapor-liquid mass transfer system which
utilizes a rotating bed of packing to
achieve high efficiency separations, and
consequent reduction in size and weight.
