Desulphurization (DeSOx)

Professional separation of environmentally harmful sulphur oxides

Flue gas desulphurization in industrial plants, power plants or waste incineration plants depends on nozzles that guarantee precise operation over a long period of time and withstand extremely aggressive environmental conditions. With its nozzle systems, Lechler offers professional and application-oriented solutions for spray scrubbers or spray absorbers as well as other processes in flue gas desulphurization (FGD).


Desulphurization applications

Wet desulphurization

Separation of sulphur oxides (SOx) and other acidic components (HCl, HF) by injecting lime suspension (limestone or lime water) into the absorber.

Wet Desulphurization

Semi-dry desulphurization

Injection of lime slurry into the spray absorber to clean the gases mainly from SOx but also other acid components like HCl and HF.

Semi-dry Desulphurization

Dry desulphurization

Cooling and humidification of the flue gas to support SOx and HCI separation in the circulating dry scrubber (CDS).
