Flue-gas desulfurization
Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration, petroleum refineries, cement and lime kilns. Flue Gas Desulphurized Gypsum (FGDG) is a by-product generated by the thermal power industry to remove sulfur dioxide (SO 3 Graphical abstract Keywords A comprehensive review of flue gas desulphurized gypsum:

A comprehensive review of flue gas desulphurized gypsum:
Analysis of FGD gypsum performed by various authors (Table 6) shows that FGD gypsum contains 36.9 54.4 % of SO 3, 28.1 46.7 % of CaO, and 0.01 3.81 % of MgO and SiO 2 with a small content of other oxides due to contamination with fly ash during desulphurization process.In coal power plants, waste incineration plants and cement factories, the wet cleaning process for flue gas desulphurization REA is often used. The gypsum produced by the REA process can be washed with gypsum Flue Gas Desulfurization System Flue Gas

Porous Materials Composed of Flue Gas Desulfurization Gypsum
During hydration, CaSO 4 2H 2 O is formed [].However, though this compound has a solubility of 0.256 g per 100 g of water at 20 °C, it cannot be used directly on the exterior of buildings because rain water will dissolve it [23, 24], although gypsum blocks are ecologically and energy friendly due to their good properties, small The manufacture of gypsum blocks from titanium gypsum can consume great amounts of it. Not only can the stacking field of titanium gypsum in the copper smelting plant be reduced and secondary pollution avoided, but the exploitation of natural gypsum can also be decreased and the mining cost saved. In this study, series of the gypsum blocksGypsum blocks produced from TiO2 production by-products

Flue-gas desulfurization
Before flue gas desulfurization was installed, the emissions from the Four Corners Generating Station in New Mexico contained a significant amount of sulfur dioxide. The G. G. Allen Steam Station scrubber (North Carolina). Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil From the experiment, it was found that the highest compressive strength of concrete brick specimens was 45.18 MPa, which was produced from 5.5% gypsum without CDW and OPT, while 26.84 MPa was the(PDF) Use of Flue Gas Desulfurization Gypsum, Construction and
