Spray Absorbers

Noell-KRC Energy and Environmental Technologies implemented the spray absorption process many times between 1986 and 2001 both in power plants and in waste-to-energy plants.

This semi-dry or also quasi-dry desulfurization process is based on an atomizer acting as the core component in the spray absorber.


  • Suitable for power stations and waste-to-energy plants of up to 800 MW
  • Low investment costs
  • Waste-water free operation
  • Dry residue product: further use in wet flue gas desulfurization plant possible (utilization of residual limestone)
  • High SO3 capture (99%) feasible
  • Highest possible aerosol capture
  • Dust capture behind absorber using bag house filter or electrostatic filter
  • Compact design
  • Excellent for retrofitting existing power stations using an improved dust capture method (no need for servicing an electrostatic filter)
