Hoe werkt een gaswasser?

A gas scrubber is a cleaning installation whose main function is to neutralize harmful components in industrial air or waste gas streams, for example to prevent fumes that have an irritating effect or cause odor nuisance. The gas particles causing these problems have to be removed from the gas stream during the process, before the gases may be disposed in the open air. In some cases, the use of a gas scrubber additionally may allow to recover certain raw materials after the treatment. A big advantage is the versatility of a gas scrubber in different sectors, including the chemical industry, the pharmaceutical industry and surface treatment.

The installation functions by bringing a gas stream in close contact with a washing liquid. Because of this contact, certain gaseous components dissolve and remain in the water. There is thus a transfer of the components from the gas phase to the liquid phase, also referred to as absorption. The solubility of the particles in the liquid will determine to what extent the gaseous components dissolve into the liquid phase.

It is thus of great importance to work with the correct fluid as the absorption agent. In addition to water, several organic or inorganic washing liquids are also used for this purpose. In these cases, certain chemicals or micro-organisms are added to the washing liquid in order to convert or neutralize the dissolved gases.

More stringent measures are taken worldwide in terms of allowed air pollution and companies are being encouraged to take the necessary measures. Gas scrubbers are legally required in industries where employees are exposed to potentially contaminated gases and are therefore often used as an abatement technique.

When a scrubber is used in an optimal manner, a very high removal efficiency of the harmful gas particles can be achieved. This means that the fumes released in the outside air are no longer damaging to the environment.
