Wet Scrubber

The exhaust gases of combustion may contain substances considered harmful to the environment, and the scrubber may remove or neutralize those. A wet scrubber is used to clean air, fuel gas or other gases of various pollutants and dust particles. Wet scrubber works via the contact of target compounds or particulate matter with the scrubbing solution. Solutions may simply be water (for dust) or solutions of reagents that specifically target certain compounds.

Process exhaust gas can also contain water soluble toxic and/or corrosive gases like hydrochloric acid (HCl) or ammonia (NH₃). These can be removed very well by a wet scrubber.^[4]

Removal efficiency of pollutants is improved by increasing residence time in the scrubber or by the increase of surface area of the scrubber solution by the use of a spray nozzle, packed towers or an aspirator. 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.

A wet scrubber or wet scrubber system is one type of scrubber that is used to remove harmful materials from industrial exhaust gases—known as flue gas—before they are released into the environment. It was the original type of scrubbing system, and utilizes a wet substance to remove acidic gases that contribute to acid rain.^[2]

When using a wet scrubber, flue gas is funneled through an area and sprayed with a wet substance. Water is used when dust and particulate matter is to be removed, but other chemicals can be added.^[3] These chemicals are chosen to specifically react with certain airborne contaminants—generally acidic gases. This process adds significant amounts of vapour to the exhaust—which causes the release of exhaust that appears as white smoke when vented.

One reason for the development of dry scrubbing was because the sprayed water added considerable weight and volume to the waste, which led to difficulties in storing and disposing of the waste material
