Liquid Distributor- Koch Knight, LLC high efficiency design provides a 50%+ open area trough type design with 4+ feed point per square foot offering better distribution of the acid over lower feed point designs. The feed points are also directed feed into the top of the bed via drip tubes to reduce entrained acid loading to the mist eliminators.

Our High Efficiency Acid Distributor is a result of the knowledge developed by the Koch-Glitsch Inc. organization over their decades of involvement in mass transfer operations. Similar designs have a history of success in a number of mass transfer operations. The high performance FLEXERAMIC® Ceramic Tower Packing is further enhanced by the use of this type of liquid distributor as packing depth is not needed to further radially distribute the initial acid loading.

Gas Injection Support Plate – a multi-beam support design configuration providing excellent gas and liquid handling capacity. Designed to incorporate gas injection where the vapor passes through the slots in the arches while liquid passes through the holes in the base of the plate, providing minimum pressure drop by keeping the vapor passage free of liquid.

  • Smaller columns > 39” – Model 77
  • Larger columns 40”-126” – Model 1212
  • Model 101 identifies all applications

LIQUID DISTRIBUTOR - Key to optimal performance of tower packing. Our high efficiency acid distributors, in alloy construction, provide better distribution of acid over lower feed points to evenly distribute the liquid across the towers cross section. Our design provides optimum liquid vapor contact which reduces the chance of poor performance due to liquid and gas channeling.

  • ORIFICE-TYPE LIQUID DISTRIBUTOR - Designed for clean service. Designed for clean service. Liquid flow is fed to the top of the packed bed through a series of orifices. A single piece design, the annular space used in conjunction with gas risers balance open area and liquid distribution coverage. Typical operational range is 2.5-3.1 turndown.
  • WEIR-TROUGH DISTRIBUTOR - Generally used in towers with high liquid rates or fouling service. Individual troughs allow for maximum open area and V-weir minimizes fouling of the distributor during operation. Each trough is engineered to maintain effective gas liquid contact over operational range of the distributor.
    • Small columns 17” – 45” – Model 378 Weir-Tube
    • Medium columns 28”- 99” – Model 127/310
    • Larger columns 42”-124” – Model 1027 with Secondary Pipe

PACKING SUPPORTS -A tower performance is directly affected by packing support design, material and load capacity. Choosing the right support for your application is essential to your systems performance.

Material

  • Fiberglass Reinforced (FRP)
  • Stainless Steel
  • Alloy
  • CPVC
  • KNIGHT-WARE® KPS™ Self-Supporting Dome Packing Support - self supporting having less than 50% open area before tower packing is installed, offering significant increased open area over standard grid bar designs.

MULTIBEAM SUPPORT - The design configuration incorporates gas injection where the vapor passes through the slots in the arches providing excellent gas and liquid handling capacity.

Material

  • Fiberglass Reinforced (FRP)
  • Stainless Steel
  • Alloy
  • CPVC
  • Aludur

BAR SUPPORT - Spacing between bars varies depending on load and material of construction. At 6” of spacing, our bar supports offer 77% open area. Most applications include sulfuric acid and chlorine drying. With random packing, some type of secondary retainer is used to prevent the tower packing from falling through the bar layout.
Lessing Rings, Cross Partition Rings and grid Blocks are used in conjunction with Bar Support Systems.
