Fabric Filter Electrostatic Precipitator

Wet Scrubber• Used on cars to reduce CO and NOx emissions.

Catalytic Converter

• Another way to lower emissions is to use a different combustion process.

SO2 + CaCO3 —> CaSO4

More than 95% of sulfur is absorbed!

Used in wall board!

Burn It Differently!

• Coal is burned in close proximity to dolomite or limestone. • Calcium reacts with sulfur to produce gypsum.

Fluidized Bed Combustion Can lead to incomplete combustion which reduces efficiency and leads to CO!

Burn It Differently!• Burns fuel at lower temperatures and with less oxygen so

nitrogen oxides don’t form.

• Balance needs to be found between temperature, oxygen, and other factors to minimize all forms of pollution.
