Fisher-Klosterman® Packed Towers
The packed tower or packed bed scrubber is used for the removal
of gaseous, fume, or mist contaminants from an air stream. Packed Bed
Scrubbers are relatively simple devices with potentially very complex
chemistry. A well designed packed tower takes into consideration many
factors and each application must be analyzed very carefully to assure
chemical compatibility of all components and still achieve the desired
results. Fisher-Klosterman, Inc. engineers are well prepared to solve
even the most difficult scrubbing applications of multiple contaminants
and can provide thoroughly integrated and smoothly functioning systems.

MPS Multi-Purpose Scrubber
The Fisher-Klosterman MPS Multi-Purpose Scrubber has a long
and successful track record in many industrial applications. The
scrubber is able to effectively cool gas streams, collect particulate,
and absorb gaseous pollutants in a single package. The inlet section,
which can include a quench section to handle gas temperatures of up to
2000 degrees F (1100 degrees C), utilizes a venturi throat to capture
particles with water droplets and send them to the separator. The
separator, or tower, includes a packing section for gas absorption along
with a mist eliminator to ensure a clean stack exhaust. The unique
design utilizes an internal tray to separate the liquid loops of each
section so that chemical usage is minimized.
- Available features:
- High temperature quench section for up to 2000 degrees F (1100 degrees C)
- Vertical or horizontal gas entry
- Various venture throat designs
- Variety of liquid injection methods
- Efficient removal of submicron particles
- 99+% gas absorption efficiency
- Multiple gas removal stages with separate liquid loops
- Integral or external recirculation tanks
- Mesh pad or chevron-style mist eliminators
- Various packing material choices
- Carbon, stainless, alloys, or FRP construction
- Performance warranty
- Complete system design and supply including: ductwork,
pumps, piping, valves, instruments, controls, chemical feed, fans and
stacks
How It Works:
When the gas temperature is more than 500 degrees F (260 degrees
C), fresh water is injected into a quench section to take the gas to a
near saturation condition. Scrubbing water is then introduced and forced
through a venturi throat where it collides with and captures
particulate. This slurry is removed in a separator section that includes
a tank for water recycling. After particulate is removed from the gas,
it enters a column of random packing where gaseous contaminants are
absorbed by a chemical reagent solution that has been sprayed on top of
the packed column using high pressure spray nozzles. This scrubbing
solution is recycled separately so that chemical usage is minimized. The
packed column’s height and diameter are determined by the contaminants
present and the required removal efficiencies. Finally, the gas passes
through a chevron or mesh pad style mist eliminator to ensure that free
water droplets are removed before it exits the scrubber tower.
