Description: system fan, recycle pump, instrumentation and controls, mist eliminator, and exhaust stack. Packed scrubbers contain packing material, structured or randomly arranged, which provides a large wetted surface for gas-liquid contact [, , ]. Features. The packing is held in place by wire mesh retainers and supported by … Control of Particulate Emissions (APTI Course 413). Type Of Packing: The key to designing a packed column for air pollution control is the tower packing. Ferric chloride is also added to the trunklines to lower H2S emissions. Water is the most common solvent used to remove inorganic contaminants. Scrubbers can be designed to collect particulate matter and/or gaseous pollutants. Therefore, vessel sizes, including fans and ducts downstream, are smaller than those of other control devices. The droplets are then collected, the liquid dissolving or absorbing the pollutant gases. Some components that are specific to the wet scrubbing process include: A system may include one or multiple of these components in addition to various supporting components such as: A typical wet scrubbing process can be described as follows: Since wet scrubbers vary greatly in complexity and method of operation, devising categories into which all of them neatly fit is extremely difficult. Packed bed wet scrubber is an air pollution control device which uses liquid to remove pollutant from the process air streams. Chemical Engineering. Richards, J. R. 1995. Wet scrubber solutions use limestone to react with sulfur dioxide before it is released into the environment via emissions. A fan draws or pushes the odorous air into the scrubber. Odor control costs are $3.5 million/year. Gas-side pressure drop refers to the pressure difference, or pressure drop, that occurs as the exhaust gas is pushed or pulled through the scrubber, disregarding the pressure that would be used for pumping or spraying the liquid into the scrubber. Tellerette® scrubber packings are a high efficiency plastic tower packing designed for use in wet scrubbers, cooling towers, mist eliminators, absorption columns and gas strippers. Conventional packings (round and cylindrical) are often specified for wet scrubbers, but Lantec tower packings defy convention! No secondary dust sources: Once particulate matter is collected, it cannot escape from hoppers or during transport. Through a nozzle or orifice a scrubbing liquid is atomized and dispersed into the gas stream. Packing types are pall rings or Rashig rings or saddles and materials are usually of plastic or ceramic; packing height should be limited to about 6 metres. © 2018 Synergies Group | GBIM - SEO Company Mumbai, Lower HTU’s: One 7” stage of KON-TANE® provides up to 3 mass transfer stages, Exceptional transfer in cross-flow scrubbers, Improve transfer in vertical towers and prevent tower replacement or modification. Packed tower scrubbers work similarly to common filters. Wet scrubbers rely on the creation of large surface areas of scrubbing liquid that allow intimate contact between the liquid and gas. It can be designed with structured packing or this packing can be filled with a small object such as Raschig rings. Pall rings, Tri-Packs, and saddles are often suitable choices. They provide a surface area equal to many other packings but with much greater liquid surface availability. Shutdowns are very short and can often be completely avoided. Also, with our offices in Mumbai as well as New Mumbai, we cater to the heavy demands of the sub-continent market. The creation of large surface areas can be accomplished by passing the liquid over a variety of media (packing, meshing, grids, trays) or by creating a spray of droplets. All collected particles are eventually washed out of the scrubber. In this text, any device fitting the definition of the first sentence is a wet scrubber. Scrubber systems can be designed to remove entrained paniculate materials such as dust, fly ash, or metal oxides, or to remove gases, such as oxides of sulfur (SOx), from a flue gas stream to meet air emission standards. Another way to classify wet scrubbers is by their use - to primarily collect either particulates or gaseous pollutants.
