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...
متن کاملBasic Properties of Flue-Gas Desulfurization Gypsum
Základné vlastnosti sadrovca pre odsírenie spalín Several hundred thousand of FGD gypsum is produced annually at the Matra Power Plant (Hungary) as a byproduct of generating electricity and protecting the environment. Chemical and mechanical characteristics of this material were studied of the Department of Mining and Geotechnical Engineering, University of Miskolc (Hungary). The material in qu...
متن کاملThermodynamic 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...
متن کاملMicrobial 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...
متن کاملCu-Cr-O and Cu-Ce-O Regenerable Oxide Sorbents for Hot Gas Desulfurization
Binary Cu-Cr-O and Cu-Ce-O oxides were studied in this work as regenerable sorbents for high-temperature fuel gas desulfurization. CuO-Cr2O3 and CuO-CeO2 sorbents can remove H2S from simulated coal-derived fuel gas to less than 5-10 ppmv in the temperature range of 650-850 °C. The presence of stable CuCr2O4 in CuO-Cr2O3 solids retains some copper in the Cu2+ or Cu1+ oxidation state, which can a...
