Packed tower scrubbers (also referred to as packed bed or packed column scrubbers) are designed for chemical scrubbing of contaminants from gas streams. Internal packing in the scrubber housing provides a large wetted surface area to induce intimate between the contaminated gas and the scrubbing liquid. The contaminant is then absorbed into or reacted with the scrubbing liquid. Recirculation of the scrubbing liquid, which may contain caustic or acid scrubbing agents, is often required to achieve the desired outlet emissions.

-Wide range of packing media including rings and saddles in various materials. Structured packing is also available.
- Complete instrumentation and electrical controls are available for stand alone operation or connection with a facility’s centralized control or monitoring systems.
-Chemical treatment, including oxidation and neutralization, is available to increase absorption of gaseous pollutants.
-Corrosion resistant fan on the inlet or outlet side of the scrubber.
-Corrosion resistant recirculating SS 316L pumps for scrubber liquid re-circulation.
-Non-plugging spray nozzles for wetting packing in a wide range of corrosion resistant materials. Special liquid distributors may also be used.
-Moisture eliminators and demister pads or loose fill type designs are available.
ADVANTAGES
-Wet scrubbers have the ability to handle high temperatures and moisture.
-In wet scrubbers, flue gases are cooled, resulting in smaller overall size of equipment.
-Wet scrubbers can remove both gases and particulate matter.
-Wet scrubbers can neutralize corrosive gases.
-Can handle flammable and explosive dusts with little risk
-Provides gas absorption and dust collection in a single unit
-Provides cooling of hot gases
-Compact; can often be retrofitted into existing collection systems
-Corrosive gases and dusts can be neutralized
