Flue Gas Desulfurization Gypsum acaa-usa

The second most common use of CCPs is flue gas desulfurization (FGD) gypsum in wallboard. This material is produced by emissions control systems (scrubbers) that remove sulfur and oxides from power plant flue gas streams. Residues vary, but the most common uses in construction applications are FGD gypsum (or "synthetic" gypsum).

What is FGD Gypsum acaa-usa

At power plants where the FGD gypsum cannot be diverted prior to disposal and/or where significant quantities cannot be marketed, the utility will not be able to justify paying subsidies to market FGD gypsum If FGD gypsum is to be accepted as a bona fide commodity, the cost of utilizing the material should be borne by the end user—payment of

The wallboard plant market consisted of the 52 wallboard plants projected to be in operation in 1985. The geographic distribution of the plants is almost entirely related to sources of gypsum, either mines or import points, as shown in Figure 2. The total wallboard plant gypsum requirements were projected to be 10.4 million ton/yr.
