Abstract: A method and composition for the reduction of the emission of selenium into the environment from the burning of fossil fuels with the use of two chemistries, either individually or in combination with each other. The method uses polydithiocarbamic compounds, including polydithiocarbamic compounds derived from a polymer produced from acrylic-x and alkylamine in conjunction with a scrubber process to capture selenium and reduce its emission in aqueous phase blowdown. The method and composition also helps reduce corrosion in the scrubber process.
