Types, Features, and Components of Wet Scrubber Systems

Last Updated: January 10, 2024By

Wet scrubbers, an emission control system, are used to remove air pollutants. It uses liquid solvents, absorbents, or reagents to settle down Particulate Matter (PM), Hazardous Air Pollutants, vapors, gases, and inorganic fumes.

A wet scrubber system is used to remove harmful materials from industrial exhaust gas (flue gas) before they are released into the Atmosphere.

The flue gas is funneled through an area and sprayed with a wet substance. Raw water is used when dust and RSPM/SPM matters are to be removed, but other recirculated liquid solutions can be added based on the properties of the constituents present in flue gas. These chemicals are chosen to specifically react with constituents.

Wet scrubbers are a special device used to remove a variety of contaminants from exhaust gas from melting furnaces or other devices. These devices use a Recirculated Scrubbing Liquid to remove the Pollutants. The exhaust gas is moved through the scrubbing liquid (usually through a Packed Chamber) and the liquid is misted through the gas. Then, the Flue gas emerges (released) without the contaminants to the atmosphere, and Contaminants/pollutants that existed before exposure to the scrubbing liquid will be transferred from the flue gas to the liquid phase. When the gas is sprayed with the Liquid solution the heavier pollutants are pulled out of the gas and attach to the liquid because of its chemical composition. As the gas is passed through the sprayed mist of scrubbing liquid solution, the contaminants are attracted to the mist and left behind.

Wet scrubber is an Emission control device that Manufacturing industries/DG sets use to reduce or remove pollutants from their exhaust streams. The gases are released by industrial exhaust contain several harmful solid pollutants and gaseous chemicals. GTS PROJECTS’s Wet Scrubbers filter the gas and eliminate any possible effects. GTS PROJECTS’ Wet scrubber devices clean the polluted air, flue gas from Diesel power generators and Boilers, Process gas stream from Petrochemical Industries, liquefied gas, and pollutants from an exhaust stream, and help a manufacturing company meet strict environmental standards and regulations. Using a wet scrubber within an industrial air stream system is the safest and most effective way to reduce pollution. The wet scrubber purifies the exhaust flow and discards the contaminants safely.

Utilizing the most current packing designs to provide contact between gas and liquid streams, the Packed Bed Scrubber achieves the extremely low toxic gas discharge limits required to meet emission standards.


Energy from the high-velocity contaminated gas stream laden with sub-micron dust particles and toxic gases is used to atomize the scrubber liquid. Intense liquid/gas mixing occurs in the HE Venturi throat, scrubbing the toxic gases and encapsulating the dust in the liquid. Proprietary gas flow patterns in the separator efficiently separate the liquid droplets from the clean gas. The clean gas exits to the atmosphere while the scrubber liquid is returned to the sump.

Chemical cleaning strippers/ Fume extractors are used to remove chemical constituents like acid fumes or other chemical compounds present in the process gas stream. Suitable solvents are used to scrub or strip the constituent to remove it from the process stream. Selection of the system depends on the raw process stream parameters test report and required percentage of removal of components, availability of space, power, and discharge limits as per Statutory standards. Post-treatment of the solvents will be required to extract the constituent stripped off or neutralize the solvent or circulating medium.
