Wet Scrubber

A Ducon Chemical Wet Scrubber is custom designed to absorb and remove SO2, HCl, H2S, TRS, Organics, odors, fumes and other toxic components. Ducon can provide spray towers using proprietary spray nozzles with no internals, packed towers with a variety of high efficiency Ducon packing, or tray towers with custom designed trays. Ducon packed towers can achieve over 99.99% removal efficiency.

packed towers

Generally speaking Chemical Wet Scrubbers work like this:

Typically a custom fan forces the polluted gas stream through Corrosion Resistant Ductwork. It then enters a Wet Scrubber, where it contacts the liquid to gas from the scrubbing solution and packing media with a high surface area. Chemical absorption of the polluted gas stream then goes into the liquid scrubbing solution through a mass transfer. Once clean the air stream then passes through a Mist Eliminator, which separates entrained mist droplets from the air stream through inertial impaction and mechanical impingement. The 99.9% 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 designed into the vessel.
