Series 5000 Packed Tower Fume Scrubber and Air StripperSeries 5000 Packed Tower Fume Scrubber and Air Stripper


Bionomic counter-current packed towers are the ideal solution to air pollution problems associated with the removal of corrosive vapors, unwanted mists, noxious and odoriferous gases. By creating a counter-current flow between contaminated gases and scrubbing liquid throughout a high surface area packed bed, rapid and uniform absorption of pollutants is achieved with maximum efficiency. Series 5000 towers are designed to accept a wide variety of packings, mist eliminators and gas scrubber liquor distribution systems. This enables the scrubbers to meet a full range of applications and gas absorption requirements.

For especially troublesome low solubility gases, scrubbers can be custom engineered to include extra depth or multiple packed beds with intermediate step chemical treatment. Construction materials include thermoplastics, fiberglass reinforced plastic, dual laminate, mild steel, stainless steel, high nickel alloys, hastalloy and corrosion resistant coating and linings.

In situations where building codes limit the height of rooftop structures, or where lower absorption efficiencies are acceptable, compact horizontal Series 5500 crossflow packed scrubbers are available.

The Series 5000 Packed Tower is also available in an air stripper version for removal of VOC compounds or ammonia from water streams.

How It Works

Fume Scrubber How it Works Diagram In the Series 5000 Packed Tower scrubbing liquid is introduced through a distributor (1) and is uniformly dispersed throughout the packed bed (2) The contaminated gas enters through the gas inlet (4) and proceeds upward through the packing support plate (5) into the packed bed section countercurrent to the downward flowing liquid. The high surface area packing elements (6) creates a tremendous amount of liquid films and droplets to enable rapid and uniform absorption of the gaseous contaminants for maximum removal efficiency. The contaminants can be physically absorbed in the liquid or chemically reacted with a reagent. Liquid droplets and any contaminants in mist form are coalesced and removed by the mist eliminator (7) before the cleaned gas exits through the top gas outlet (8). The scrubbing liquid then drains into the reservoir (9) and exits the unit through the liquid outlet connection (10) where it can be recirculated partially or fully depending on the service with a pump or utilized on a once through basis.

Special Features Include

  • Reinforced Gas Inlet and Outlet - Flanged inlet sized uniform gas distribution with minimum entrance flow losses. Rugged flanged outlet capable of supporting the weight of an axial flow fan, stack or unsupported ducting.
  • Easy Access Liquid Distributors - Liquid distributors are bolted to the tower for easy removal and inspection. Low pressure, non-clogging spray nozzle arrangements achieve uniform liquid distribution for low to medium capacity towers. High capacity units are fitted with special trough-type high efficiency distributors.
  • Multiple Mist Eliminator Designs - Under normal conditions, our standard knitted wire mesh pad mist eliminator superbly separates the incoming liquid from the vapor. When high mist concentrations, fine mists or scrubbing liquids that contain depositing solids are present, we recommend our special interlaced filament mist eliminators or packed bed sections.
  • Choice of Packed Bed Section - The absorption efficiency of the packed bed section depends upon the choice of types and sizes of packings, and the bed depth. These are selected by our engineers to meet the pollution treatment requirements. Multiple beds with redistributors are available for difficult applications.
  • Optimum Selection of Bed Support Plates - Three different styles of bed support plates are offered so that the gas distribution and packing support requirements can be precisely matched. Large open passages in the plates permits complete washdown of depositing solids and minimal gas friction losses.
  • Large Capacity Integral Recycle Section - A standard feature on all Bionomic counter-current packed towers, this eliminates the need for separate recycle or chemical neutralization tanks in most installations. Recycle sections are available with optional sloped, dished and cone bottoms in lieu of flat for better drainage on scrubbing liquids that tend to sludge or solidify.

Capacity Size Range

  • 400 thru 70,000 cfm
