Counter-current gas scrubber / wet type / nitrogen oxide / high-efficiency

Efficient solution for little space

Counter-current scrubbers are cost-effective solutions for single-substance problems. These substances being highly harmful to health and environment must be cleaned to very low clean gas concentrations before being released into the atmosphere. Some examples are: Hydrochloric acid, hydrogen fluoride, formic acid, nitrogen oxides, formaldehyde, acetone, sulphuric acid, chlorine gas and organic solvents. High removal efficiencies of 95 - 99 % are therefore generally required to ensure compliance with legal limit values.

Function principle

The principle of the counter-current scrubber is the separation of contaminants from the gas phase into the liquid phase. The waste gas streams upwards through a packed bed and gets in contact with the downwards flowing washing liquid which is sprayed out from the irrigation system placed above the packing bed. Thus, the gas to be cleaned flows in counter-current to the washing liquid.

Main function of the packing material hereby is to increase the transfer of the contaminants from the gas phase into the liquid phase. This is possible due to the very high active surface able to hold up a big amount of washing liquid. Plently of droplets are built on the surface of the packing material, segmented and re-shaped constantly. Through this intense contact between waste gas and washing liquid, the contaminants are separated, accumulate in the liquid phase and can be eliminated.

Counter-current systems of gas and liquid circulation lead to the highest contaminants transmission capacity.
