Flue gas desulfurization

Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...

Emission and Leaching Potential of Mercury from Flue Gas Desulfurization (FGD) Byproducts Amended Soil

The release of mercury (Hg) into atmosphere, infiltration, and uptake by plants from flue gas desulfurization (FGD) material-amended soils was studied. The project was carried out in three phases: (1) laboratory study, (2) field study, and (3) life cycle calculation. In the laboratory study, factors controlling the release of Hg from FGD by-product amended soil were investigated under well-cont...

Thermodynamic Analysis of Pyrolusite for Dry Flue Gas Desulfurization

Various approaches to flue gas desulfurization by low-grade manganese and high efficiency desulfurization in sintering enterprises were investigated, and the predominance areas of the Mn/Fe-S-O system were constructed in this paper. Additionally, the areas in different temperatures were established based on the thermodynamic properties achieved from manuals. From the view of thermodynamics, man...

Microbial communities associated with wet flue gas desulfurization systems

Flue gas desulfurization (FGD) systems are employed to remove SO(x) gasses that are produced by the combustion of coal for electric power generation, and consequently limit acid rain associated with these activities. Wet FGDs represent a physicochemically extreme environment due to the high operating temperatures and total dissolved solids (TDS) of fluids in the interior of the FGD units. Despi...
