Dry Flue Gas Desulfurization SOx Control GE

Spray Dryer Absorber (SDA) This conventional dry FGD system has been widespread for many years. It’s made up of a reactor followed by a fabric filter. In the reactor, the reagent slurry solution is atomized using either GE’s rotary atomizer technology or dual fluid nozzles, and the droplets react with the gaseous pollutants in the flue gas stream.

Flue-gas desulfurization - Wikipedia

Lime is typically used on large coal- or oil-fired boilers as found in power plants, as it is very much less expensive than caustic soda. The problem is that it results in a slurry being circulated through the scrubber instead of a solution. This makes it harder on the equipment. A spray
