Contact SupplierPacked-bed scrubbers consist of a chamber containing layers of variously shaped packing material, such as Pall rings, Raschig rings or Berl saddles that provide a large surface area for liquid-gas contact. The packing is held in place by wire mesh retainers and supported by a plate near the bottom of the scrubber. Scrubbing liquid is evenly introduced above the packing and flows down through the bed. The liquid coats the packing and establishes a thin film. The pollutant to be absorbed must be soluble in the fluid. In vertical packed bed scrubber, the gas stream flows up the chamber (countercurrent to the liquid).
