Wet Scrubbers benefits Simplicity of construction and operation; Flexibility of operation (gas volume, acid gas concentration, etc.) Our equipments used for a wide range of gases-fumes-dusts, such as Acid fumes (HCL, H2SO4, HNO3 etc) HCL gas-cl2-so2-Nox-NH3-H2S-FLU gases – Furnace gases & other gaseous effluent. Monroe Environmental Packed Bed Wet Scrubbers provide efficient removal of acid gasses, alcohols, soluble organics, fumes, & odors from contaminated air streams. Our scrubbers maximise the gas liquid contact area whilst minimising the pressure drop through the scrubber. Since residence time in the scrubber is a critical design consideration, the volume of air passing through the scrubber directly affects the cross sectional area. Environmental Safety through Critical pH Control Wet gas scrubber systems, also known as chemical scrubbers or gas scrubbers, are a type of air pollution control system. By-products and waste gases that can be removed during scrubbing can include hydrochloric acid (HCl), hydrogen sulfide (H 2 S), chlorine (Cl 2), and sulfur dioxide (SO 2). Scrubbers are effective air pollution control devices for removing particles and/or gases from industrial exhaust streams. Acid fume scrubbers remove or neutralize the harmful substances emitted from combustion or the storage of chemicals. Wet scrubbers use a liquid to remove pollutants from a contaminated gas stream via absorption. Caustic solution (sodium hydroxide, NaOH) is the most common scrubbing liquid used for acid-gas control (e.g., HCl, SO 2, or both), though sodium carbonate (Na 2 CO 3) and calcium hydroxide (slaked lime, Ca[OH] 2) are also used. Scrubber is a general term that describes air pollution control devices or systems that use absorption, both physical and chemical, to remove pollutants from the process gas stream. Inside the tank are water spray nozzles. Current designs can achieve more than 99% SO 2 removal, with system availability greater than 99.5%.
