This increases air quality and lowers the health risks for people who could come into contact with the different pollutants.Īlthough there are many positive side-effects of using scrubbers, there are still waste products from the scrubbing process whether wet or dry scrubbing is used. By collecting particulate matter and acidic gases, the amount of different pollutants that can exit the plant and be introduced into the environment is dramatically reduced. The use of scrubbers to clean flue gases before they leave the smokestacks has a drastic, beneficial impact on the environment. Additionally, it is energy intensive as the flue gas must be reheated after coming into contact with water vapour in the wet scrubber for the gas to be buoyant enough to exit through the smokestacks. Scrubbers are very effective, removing about 98% of sulfur from flue gases, but they are very expensive to maintain and install. This calcium sulfite either falls out of the gas stream or is removed with other particulates. The chemical reaction between the calcium carbonate and the sulfur dioxide yield calcium sulfite.

If a dry scrubber is used, the flue gas comes into contact with pulverized limestone - which is mainly calcium carbonate. Generally speaking, the main chemical is calcium carbonate. Removing the sulfur oxides is fairly simple, the flue gases pass through a spray of water in a wet scrubber that contains a variety of chemicals. Scrubbing, sometimes referred to as flue gas desulfurization is the most effective sulfur-removal technique that is in widespread use.
