WebThe scrubber itself (dissolution of system materials, possible reaction products and/or chemical additives). The use of scrubbers to clean the exhaust from marine engines using high sulfur residual oil and diesel fuels may lead to high concentrations of a number of harmful compounds in the water body around the ships (AEA, 2009). WebDry scrubbers spray very fine absorbents into a vessel where they combine with flue gases. The resulting sorbent is captured by the scrubber media, called a baghouse. Different scrubber media remove pollutants in multiple ways, including electrostatic adhesion and chemical reactions.
