 Metal Structured Packing

        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 / benzene second, hexamethylene kelone/ hexamethylene mellow, oneself lactam. absorb or regeneration tower.

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 1.5—2m/s kg/m3. minimum liquid load approx: 0.2 m3/m2Ěh
