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). A wet scrubber is an air pollution control device that uses liquid to remove contaminants/gases from the exhaust streams. A Wet Scrubber operates by introducing the dirty gas stream with a scrubbing liquid – typically water. H2S, will be removed by caustic solution. Wet scrubbers may increase the proportion of water in the gas, resulting in a visible stack plume, if the gas is sent to a stack. Particulate or gases are collected in the scrubbing liquid. Wet scrubbers that remove gaseous pollutants are referred to as absorbers. Current designs can achieve more than 99% SO 2 removal, with system availability greater than 99.5%. Wet scrubbers work by passing the dirty gas through a liquid compound that is designed to react with the targeted acid gas for removal from the dirty stream. Monroe Environmental Packed Bed Wet Scrubbers provide efficient removal of acid gasses, alcohols, soluble organics, fumes, & odors from contaminated air streams. For wet scrubbers used to control acid gas emissions, monitoring scrubber liquid pH is an adequate surrogate for scrubber liquid outlet concentration. In most cases, the liquid is water, as it is readily available at most facilities. Our specialised systems are suitable for removing suspended liquids from the air. 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. Anguil - Acid Gas Control - Wet Scrubbers. Gas flow rate is generally a constant parameter and may be monitored to ensure that the flow is within design range. Our wet FGD systems, or wet scrubbers, have operated efficiently, economically and reliably since 1971. Technologies for SO2 and Acid Gas Control. Scrubbers are effective air pollution control devices for removing particles and/or gases from industrial exhaust streams. Some of the chemicals that can be vented from tanks are hydrochloric acid, ammonia, and acetic acid. Due to the acidity of HCl, it is somewhat more effectively scrubbed using an alkaline solution. Many Wet Sulfuric Acid Scrubbers utilize a multi-stage approach, first using a bed of packed media with recirculated liquid caustic (sodium hydroxide solution) which acts as a base to neutralize the acid, and finally uses a mist eliminator to remove water vapor. Our specialised systems are suitable for removing suspended liquids from the air. For wet scrubbers used to control acid gas emissions, monitoring scrubber liquid pH is an adequate surrogate for scrubber liquid outlet concentration. UK Enviro design & manufacture high efficiency Wet Scrubber For Wire Pickling for meeting pollution control board’s norms for outlet emission.
