Abstract: The disclosure relates generally to reducing mercury emissions from a coal power plant. Specifically, a method for treating a gas stream containing mercury is provided that includes injecting a mercury oxidant or absorbent and a carrying agent into a gas stream that was produced by heating or burning a carbonaceous fuel comprising mercury. The carrying agent vaporizes after being injected into the gas stream. The mercury oxidant or absorbent and a carrying agent may be injected before passing the gas stream into a gas scrubber.

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.

Abstract: Disclosed are methods for controlling, mercury emissions, and more particularly, to methods for controlling mercury re-emissions from a wet flue gas desulfurizer used in a combustion process. A method of controlling mercury re-emission from a combustion process includes measuring either mercury concentration, oxidation-reduction, potential (ORP), and/or sulfide concentration within a scrubber liquor of a wet flue gas desulpherizer (wFGD); correlating the mercury concentration, ORP, and /or sulfide concentration with an amount of mercury re-emission additive required in the scrubber liquor to reduce and/or prevent mercury re-emission to a selected level; and adjusting the rate of addition of mercury re-emission additive into the scrubber liquor to attain the selected level of mercury re-emission.
