  • SO2 Scrubbers | Emerson US

    Sulfur Dioxide (SO2) is a harmful by-product of power generation such as coal and fossil-fuel burning. Exhaust from incinerators and fossil-fuel power plants are required to pass through an SO2 Scrubber before entering the atmosphere. SO2 Scrubbing, also known as Flue-Gas Desulfurization (FGD), can remove 90-99% of SO2.
