Mechanism
Packed-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).

Physical absorption depends on properties of the gas stream and liquid solvent, such as density and viscosity, as well as specific characteristics of the pollutants in the gas (e.g., diffusivity, equilibrium solubility). These properties are temperature dependent, and lower temperatures generally favor absorption of gases by the solvent.

Industrial dry scrubber

Dry Scrubber
A dry scrubber, or dry scrubber system, is a type of pollution control equipment that is designed to remove harmful gases and particulates from industrial exhaust streams. Dry scrubbers are primarily used to abate solvent and acidic gases. This is one of the most common pieces of equipment found in manufacturing plants, because of its ability to handle less concentration of pollutant, highly acidic exhaust streams.

Working principle

A dry scrubber works by combining carefully chosen chemical reagents with the exhaust stream at incredibly high speed, which react with or adsorb the compounds in the stream. These chemicals react differently, depending on which compounds are being targeted; reactions either neutralize the dangerous Volatile organic compounds (VOCs) or adsorb them into a different compound all-together. Once converted, the substance left over can then be disposed of or transported easily. Each type of scrubber media removes particles and compounds in a different way; some chemical reactions, while others use electrostatic adhesion.
