AceChemPack Structured
Column Packing is formed from vertical sheets of corrugated thin gauge
ceramic / metal/ plastic with the angle of the corrugations reversed in
adjacent sheets to form a very open honeycomb structure with inclined
flow channels and a relatively high surface area. To simplify
installation, it is delivered in preformed slabs or segments that are
sized to fit through the vessel manways. A high surface area will only
provide efficient mass transfer if it is effectively used to increase
vapour liquid-contact and therefore a variety of surface enhancements
are available to promote liquid spreading over the packing surface. The
low resistance to vapour flow together with efficient use of available
surface tends to give structured packings significant performance
advantages over random packings in high vapour rate/low liquid rate
systems.
AceChemPack offers two performance-improving structured packings:
AceChemPack Corrugated Structured Packing, fabricated from ceramic, sheet metal or engineered plastics,
and wire gauze packing.
Corrugated Structured Packing
AceChemPack Corrugated structured packing is constructed of sheets of corrugated
metal or plastic. 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?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. AceChemPack Corrugated structured packing operates over a wide range of liquid and
gas rates. With more than 10 types of AceChemPack Corrugated packing
available, AceChemPack can provide the right products to meet your specific tower
requirements.
AceChemPack Corrugated
packing offers higher capacity and/or higher efficiency than random
packing or conventional trays. AceChemPack Corrugated 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
AceChemPack Corrugated packing will improve profitability.
Application:
AceChemPack corrugated structured
packing widely used in temperature sensitive application where large
number of theoretical stages are needed. Low liquid loading systems for
vacume distillations or organic intermediates, amines, glycols, fatty
acids, essential oils and fragrances. Suitable for solvent recovery,
batch & continuous distillation system. and system of ethylbenzene

Wire Mesh
Structured Packing
AceChemPack 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.
Features
Good lateral
distribution of liquid and gas. Highest theoretical stages per
meter of packed height. Lower specific pressure drop per
theoretical stage. Less liquid hold up. Economic operating
loads. The weir mesh packing with
high number of theoretical plates and low pressure drop per
meter. Small hold-up, most economical load range: F factor
