Abstract The release of mercury from flue gas desulfurization (FGD) gypsum in the manufacture of 100% FGD wallboard was studied. Calcination, with product temperatures ranging from 150 to 180 °C, appears to be the most likely process to release mercury from the FGD.

Controlling acid deposition: the role of FGD
Environmental Science & Technology, 1986This article examines the important technical, economic and policy factors affecting the extent to which FGD systems may be required at existing coal-fired power plants, if new SO/sub 2/ emission reductions are mandated to control acid deposition. It discusses currently available sulfur removal technologies, as well as several that are still under ...

The Treatment and Recycling of FGD Waste
Advanced Materials Research, 2014At present, wet lime - gypsum flue gas desulfurization (FGD) technology is very common in the field of gas desulfurization technology. In addition, wet carbide slag - gypsum FGD and Magnesia FGD are also used. In the process of eliminating SO2, with the first two technology, the byproducts of desulfurization wastewater and gypsum will be produced; With

Transport Processes Involved in FGD
1998This chapter describes the investigations conducted to improve the understanding of the transport processes related to dry flue gas desulfurization (FGD). It is important to improve the understanding of the various processes involved in FGD; e.g, dry sorbent injection and dispersion, sorbent and flue gas mixing, sor-bent humidification by water ...

FGD Materials Guideline and Software
CORROSION 1993, 1993Abstract Corrosion and erosion have been main causes of failure and shutdown in first-generation flue gas desulfurization (FGD) systems. A wide variety of construction materials have been used and new materials are continually being tested and applied, with varying degrees of success.

This chapter contains the findings of 21 focus group discussions (FGDs) that were carried out in 10 districts of Bangladesh and involved 237 youth between the ages of 18 and 35 years. The sampling strategy employed for the FGDs is discussed. The ethical issues encountered while carrying out the FGDs is then briefly recalled.
