Spray scrubbers

flexible solutions for pollutant removal and gas cooling

Our spray scrubbers provide efficient gas cleaning and cooling in a single system. 

Two main applications

Pollutant abatement: Perfectly designed for gas absorption with quicklime or limestone suspensions. The open, internal-free construction ensures maximum resistance to fouling and deposits, drastically reducing maintenance downtime.
Gas cooling (quenching): Hot gases are cooled through the evaporation of finely atomized liquid.

 

How does it work?

In a spray scrubber, the gas stream is contacted with finely dispersed liquid droplets, enabling efficient mass and heat transfer. Pollutants are absorbed while the gas temperature is reduced in a controlled manner. 

For hot gas applications, a continuous liquid film protects the column wall from thermal stress. This design allows even highly corrosive hot gases to be treated economically and reliably. 

 

Available materials

Stähle, PP, PE, PVC, PVDF, ECTFE, GFK, Grafit, Nickelbasislegierungen, Titan, Tantal
