Dipak K. Sarkar, in Thermal Power Plant, 2015 14.4.7 Seawater FGD. Seawater FGD is attractive to plants that are located near coastlines. Seawater is a source of natural alkalinity that can be used economically to arrest SO 2 from flue gas without the use of any other supplemental reagents. Seawater contains significant concentrations of alkaline ions including sodium, magnesium, potassium ...
The gypsum, however, has a moisture content of up to 20 %, which is why it could only be used wet or slightly dried. Also, it was only used locally in this cement works. In the planned dryer plant the moisture of the FGD gypsum will be reduced to a residual …
The paper concludes by describing the important information that power plant engineers should review before deciding on a solid-liquid separation technology. These parameters include type of FGD process, type of coal, limestone purity, water analysis, operating data, composition of the gypsum slurry and other upstream or downstream equipment.
FGD gypsum, largely in cement and construction. In India as well, gypsum is an integral component of cement production and the sector has to rely on costly imports or poor quality synthetic gypsum. By adopting FGD, India's power plants would produce around 12–17 million tonnes of gypsum which
Limestone-Gypsum FGD Wet Desulphurization. 1. Introduction of Flue-gas Desulfurization. Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO. 2) from exhaust flue gases of fossil-fuel power plants, steel company etc, and from the emissions of other sulfur oxide emitting processes.
The final FGD waste is wallboard-grade gypsum. Limestone Forced Oxidation Flue-Gas Desulfurization Process Note: FGD = flue-gas desulfurization By controlling the gypsum quality in the dewatering step, a wallboard-grade gypsum can be produced. The majority of scrubber installations in Europe and Japan generate gypsum for reuse.
Coarse natural gypsum or mixtures of such gypsum with FGD gypsum are ground, dried, calcined, and classified in the Pfeiffer vertical roller mill. To be noted that up to 20% of recycling material may be added if required. Product fineness and product properties can be adjusted within wide limits (0.063 to 0.5 mm).
