Packed Bed Scrubber

Product Description

Packed Bed Wet Scrubbers are used to remove acids, soluble gases, chemicals, fumes and odors. The contaminated air flows through the packing media that is specially designed for each application. It is wetted with recirculated liquid. Liquid solvent is used to absorb the gas pollutants. A blow down from the tank with makeup water removes the contaminant products before they precipitate.
Packed bed scrubber enlarges the space between the fluid and the gas that is exhausted. This helps in purifying the exhaust gas with its internal special pieces. Special hollow thermoplastics are used in packing which helps in removing soluble gases like HCl, Cl, BR2, NH2, SO2, H2S, & Nox.
Scrubber efficiency usually depends on the interfacial area between the liquid, gas and the turbulence at the interface. Gas, liquid flows and the required concentration change are the most important design parameters that are considered while designing the scrubber column.
