FGD Gypsum Wallboard Production Process: Introduction to FGD Gypsum. FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers."
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).

Jul 30, 2010· Synthetic gypsum, which is now used in about 30% of drywall, is a byproduct of coal-fired power plants. It is sometimes confused with fly ash—another coal combustion product that’s been in the news recently—but the two have very little in common. Synthetic gypsum is also called flue-gas-desulfurization (FGD) gypsum.
Most FGD systems employ two stages: one for fly ashremoval and the other for SO 2 removal. Attempts have been made to remove both the fly ash and SO 2 in one scrubbing vessel. However, these systems experienced severe maintenance problems and low removal efficiency. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO 2-absorber. However, in dry injection or spray drying operations, the S
Using flue gas desulfurization (FGD) gypsum in gypsum panel products is recognized by the EPA as an important contribution to sustainable materials management because it uses a non-hazardous secondary material, FGD gypsum, as a substitute for natural gypsum. Plant scrap and dunnage are also regularly returned to the manufacturing process.

Gypsum that comes from coal plants is called flue-gas desulfurization gypsum, as it comes from the process that 'scrubs' sulfur out of the smoke stacks to reduce air pollution. "The gypsum that is
Electric utilities produce more than 11.2 million Mg of flue gas desulfurization gypsum annually. Approximately 7.5 million Mg are used in wallboard production. This paper examines the environmental and cost benefits associated with replacement of natural gypsum in wallboard with flue gas desulfurization gypsum. A
The 1985 marketing potential of byproduct gypsum from utility flue gas desulfurization (FGD) was evaluated for the area east of the Rocky Mountains using the calculated gypsum production rates of 14 selected power plants. The 114 cement plants and 52 wallboard plants in the area were assumed to be the potential market for FGD gypsum sales.

Flue Gas Desulfurization (FGD) Gypsum –Wallboard At least 20 wallboard plants are operating or have been announced which will run on FGD Gypsum Total usage in these plants will approach 3-5 M tons/yr accounting for a total of 12 M tons/yr. Illustration courtesy of
For more than 20 years, Gypsum Association members have successfully and safely developed and deployed technologies to use flue gas desulfurization (FGD) gypsum as a key ingredient in the manufacture of gypsum board (AKA wallboard or drywall). The gypsum industry purchases FGD gypsum from electric utilities who employ a washing and purification
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.

Synthetic gypsum produced by wet flue gas desulfurization (FGD) systems on coal-fired power plants is commonly used in the manufacture of wallboard. This practice has long benefited the environment by recycling the FGD gypsum byproduct, which is becoming available in increasing quantities, decreasing the need to landfill this material, and

Flue Gas Desulfurization (FGD) gypsum is a synthetic by-product generated from the flue gas desulfurization process in coal power plants. It has several beneficial applications such as an ingredient in cement production, wallboard production and in agricultural practice as a soil amendment due to its abundance, particle size, chemical and physical similarities to natural gypsum and the purity

Synthetic gypsum is created from environmental control systems installed in the smokestacks of coal-fired power plants. These systems capture particles from coal burning as they travel through the smokestack or flue. This becomes synthetic or flue-gas desulfurization (FGD) gypsum, which is considered pre-consumer recycled content.
