Metal Structured Packing
Product No: TPU®-MSP
Metal Corrugated Structured Packing:
Metal Corrugated Structured Packing is constructed of sheets of
corrugated metal. The angle of inclination of the corrugations of
adjacent sheets is reversed with respect to the vertical column
axis, forming mixing cells at every point where the corrugations
intersect. Perforations and surface texturing, including waffled,
grooved and smooth, promote intimate mixing and radial distribution
over the entire tower cross-section. Each subsequent element is
rotated 90 degree about the column axis so that the sheets of one
element are perpendicular to the sheets of the elements above and
below. In passing through each element, gas and liquid are
thoroughly mixed in the direction parallel to the plane of the
sheets. By rotating subsequent elements, excellent mixing and
spreading, both side-to-side and front-to-back are obtained over the
entire cross-section of the tower. Metal Corrugated Structured
Packing operates over a wide range of liquid and gas rates. With
more than 10 types of TPU Corrugated Packing available, TPU can
provide the right products to meet your specific tower requirements.
Metal Corrugated Structured Packing offers higher capacity and/or
higher efficiency than random packing or conventional trays. Metal
Corrugated Structured Packing revamp can increase separation
efficiency, increase capacity, lower pressure drop, and often
significantly lower the energy costs of distillation and absorption
operations. That means retrofitting existing packed or trayed towers
with Metal Corrugated Structured Packing will improve profitability.
Application:
Metal Corrugated Structured Packing widely used in temperature
sensitive application where large numbers of theoretical stages are
needed. Low liquid loading systems for vacuum distillations or
organic intermediates, amines, glycols, fatty acids, essential oils
and fragrances, suitable for solvent recovery, batch & continuous
distillation system and system of ethyl benzene / benzene second,
hexamethylene kelone/ hexamethylene mellow, oneself lactam. Absorb
or regeneration tower.
Materials: Stainless
steel, Carbon steel, aluminum, bronze and special alloys.

Metal Wire Mesh Structured Packing
Metal Wire Mesh structured columns packing consist of proprietary
designed metal wire mesh with corrugated sheets which are aligned
and placed vertically. The wire structures slopes are reversed in
other sheets stacked with alternating 90 degree orientation of each
layer resulting in inclined flow passages and a relatively high
surface area. This allow thin liquid films to be continuously spread
across the tower as liquid flows through the packing. Capillary
action and high surface areas result in maximum exposure to high
mass transfer efficiency.
