Tower Scrubbers for Gaseous Contaminants
Description
Series 5000 Counter Current Packed Tower Scrubbers 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.
Engineered for use with water, reactive chemical reagents or special solvent scrubbing liquids to reduce costs and recover or minimize liquid waste, the scrubbers provide up to 99.9% removal efficiency and are available in a full range of sizes for gas flow rates from 30 cfm thru 300,000 cfm.
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.
Specs
Features:
- 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.
