Scrubber | Wiki | Everipedia
Scrubber's wiki: Scrubber systems (aka Chemical Scrubbers, Gas Scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used till today....

Dry scrubbers remove acid gases from combustion sources ...
Dry scrubbing systems are used to remove acid gases (such as SO2 and HCl) primarily from combustion sources. Dry scrubbing systems consist of two main sections or devices: the scrubber and the scrubber media. Dry scrubbers spray very fine absorbents into a vessel where they combine with flue gases....
FlueGas Desulfurization ("Scrubbers")
effluent hold tank directly. The amount of limestone in the liquid is determined using stoichiometry (1 mole of CaCO3 for 2 moles of SO2, that is, 100 g of limestone per 128 g of sulfur dioxide removed from the flue gas) and is easily controlled by monitoring the pH, since it makes an alkaline solution....
Hydrated Lime | Mississippi Lime
Hydrated lime, also known as calcium hydroxide {Ca(OH) 2}, is a refined mineral oxide is stoichiometrically reacted with water in a controlled process to form a hydrated lime product that has the consistency of a fine white powder containing less than 1% residual moisture....
How Do Air Scrubbers Work? | Sciencing
Wet scrubbing can clean air, flue gas or other gases. A mixture of water and limestone, or other specifically targeted chemicals, is sprayed into the smokestack. The mixture, or slurry, goes through a nozzle, or the polluted gas can be directed through a tube packed with the mixture....
British Lime Association (BLA) part of the Mineral ...
Lime products can therefore provide a cost effective, efficient solution to the treatment of flue gases generated from the energy recovery process, which reduces the waste volumes sent to landfill. A variety of flue gas abatement techniques have now been designed to suit particular applications, some of which are described below. Dry scrubbing...
Filtering flue gas | Waste Management World
The removal of acidic components in the flue gas is done, by injection of hydrated lime or a similar product in the flue gas, in reactors of various shapes. There are simplydesigned ones, such as an injection point in the flue gas pipe, and much more sophisticated ones such as atomizers or fluidized bed reactors. Figure 1....
