Scrubber Technology Customized multi-stage gas scrubber systems

Multi-stage scrubbers

Exhausts from industrial processes often require cooling, dedusting or removal of gaseous pollutants. In many cases, scrubbers are of advantage for these duties. GEA offers Venturi scrubbers and jet scrubbers which are the most widely employed scrubber types. Often applications require counterflow-columns with packings (packed-bed, packings, trays) or a combination of these columns and jet scrubbers.

Wet scrubbers

Wet scrubber have 3 main tasks:

  • Cooling/saturation of gas flow by evaporation of water
  • Dust removal by using inertia effect
  • Removal of harmful gases by using absorption (dissolving of gaseous substances in liquids) 

GEA offers a complete series of scrubber types which can be combined with each other, depending on the application and on the specific requirements. Customized needs are optimally taken into account. A high purity of the exhaust air and low residual product quantities are ensured.

The following scrubber types are used depending on the respective application:

  • Jet scrubbers
  • Submerged scrubbers 
  • Venturi scrubbers 
  • Columns

The apparatuses specified above are ideally suitable for dust removal, absorbing pollutants as well as for recovering valuable substances.
