  • AMT - Recommendations for spectral fitting of SO2 from

    Abstract. Fitting sulfur dioxide ( SO 2 ) differential slant column densities (dSCDs) from multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements of scattered sunlight is challenging because actinic light intensity is low in the wavelength regions where the SO 2 absorption features are strongest.

  • 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.
