Also known as Wet Scrubbers, Fume Scrubbers or Gas Scrubbers
Cross Flow Scrubber with Fan and Common Base
KCH designs, manufactures, and installs a variety of corrosion resistant scrubber systems for many applications requiring control of Hazardous Air Pollutants (HAPs) or control of noxious odors. Our scrubbers are available in corrosion resistant materials such as PVC, FRP, Polypropylene, POLYSTRONG®, POLYLAST®, and SS.
Sizes from 100 CFM to 80,000 CFM in one vessel.

Vertical Counter-current Scrubbers typically provide the most efficient removal of soluble acid gases. Counter-current refers to the direction of the contaminated airstream in relation to the fluid that scrubs it.

Horizontal Cross-flow scrubbers are commonly used in the surface finishing industry where space is limited and inlet loadings are relatively low. The rooftop is an ideal spot for these compact scrubbers if headroom is insufficient.

Bidirectional flow scrubbers utilize multiple stages of concurrent and counter-current flow in one unit to scrub a variety of noxious gases and odors. They are commonly recommended when multiple compounds need to be removed from one airstream.

An Exhaust Fan forces or induces the polluted gas stream through Corrosion Resistant Ductwork and into the Wet Scrubber vessel, where it encounters liquid to gas contact from the scrubbing solution and packing media with high surface area. The polluted gas stream is chemically absorbed into the liquid scrubbing solution through mass transfer. The clean air stream then passes through a Mist Eliminator, which separates entrained mist droplets from the air stream through inertial impaction and mechanical impingement. The clean airstream is then exhausted to atmosphere. Some gases, such as HCL, can form an aerosol or "acid fog" inside the Wet Scrubber vessel as it cools. To mitigate this problem, a high efficiency Composite Mesh Pad Mist Eliminator is incorporated into the design.
