Over the past several decades there have been immense improvements in process chemistry, a better understanding of materials, simplified designs, and other technological enhancements. Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO₂) from exhaust flue gases of fossil-fuel power plants and the emissions of other sulfur dioxide-emitting processes. SO₂...

Smokestack Scrubbers: a New Component to Industrial Exhaust Systems
Power plants burn coal, creating smoke and fumes that pose a significant risk to the health of residents living downwind. The federal government is now trying to solve this problem. It seems that the simplest solution is the adoption of a tighter emission standard. However, the smokestack may turn out to be one place where...

Best Practices for Underground Coal Mines: Wet Air Scrubbers in Mining
Wet air scrubbers are devices used in underground coal mines for the exhaust air treatment system of various internal combustion engines, primarily as spark arrestors. Their secondary function is to remove pollutants from the exhaust gas. Wet scrubbers are widely used in underground applications of diesel particulat. They are relatively small, making it easier to...

A New Perspective on the Shipping Industry: the Environmental Impacts of Exhaust Gas Scrubber Discharge
Wet air scrubbers use seawater or freshwater as cleaning media for sulfur dioxide. They are utilized by shipping companies to comply with emissions regulations. Shipping emissions are expected to rise considerably, in parallel with a growing focus on the sustainability and ecological effects of the maritime transport industry. Gas and particulate emissions into the atmosphere affect...
