How CO2 Scrubbing Works | HowStuffWorks

CO 2 ­ ­scrubbing is a particular form of carbon capture that takes place after fossil fuel has been combusted, but before the exhaust is released into the air. ­Aside from its currently hefty price tag, many people see CO 2 ­ scrubbing as one of the easiest ways to reduce carbon dioxide emissions since it doesn't require any lifestyle changes.

Coal plants without scrubbers account for a majority of SO

Coal plants without scrubbers account for a majority of SO

SO 2 is formed during the combustion of coal. The amount of SO 2 produced depends on the sulfur content of the coal burned in a boiler. FGD scrubbers remove the SO 2 from a boiler's postcombustion exhaust (flue gas) by passing it through an alkaline solution. This process is also effective in removing acid gases, such as hydrochloric acid.
