Status review of mercury control options for coal-fired power plants
John H. Pavlish,Everett A. Sondreal,Michael Mann,Edwin S. Olson,Kevin C. Galbreath,Dennis L. Laudal,Steven A. Benson +6 more
TL;DR: In this article, the authors present an overview of research related to mercury control technology for coal-fired power plants and identify areas requiring additional research and development, including the chemistry of mercury transformation and control; progress in the development of promising control technologies: sorbent injection, control in wet scrubbers, and coal cleaning; and projects costs for mercury control.
Journal ArticleDOI
Control of mercury emissions from coal-fired electric utility boilers.
TL;DR: The authors review the effectiveness of technologies already available to reduce other pollutants at holding the line on mercury and explore how they can be improved for deeper emission cuts.
Journal ArticleDOI
The aqueous reduction of divalent mercury by sulfite
TL;DR: In this article, an instable intermediate, HgSO3, which decomposes to produce Hg+ which in turn is rapidly reduced to Hg0. This reaction may influence the concentration of Hg in cloud and rain-water by reducing water soluble Hg2+ to volatile Hg 0.
Journal ArticleDOI
Reduction of the Aqueous Mercuric Ion by Sulfite: UV Spectrum of HgSO3 and Its Intramolecular Redox Reaction
TL;DR: Aqueous hydrogen sulfite reacts with Hg2+ to form, in the absence of excess HSO3-, the HgSO3 complex, observed here for the first time.
Journal ArticleDOI
Simulation and evaluation of elemental mercury concentration increase in flue gas across a wet scrubber.
TL;DR: Experimental data and model simulations confirmed that oxidized mercury, Hg2+, can be reduced by aqueous S(IV) (sulfite and/or bisulfite) species and results in elemental mercury (HgO) emissions under typical wet FGD scrubber conditions.
