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.

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

Impact/Purpose: Flue gas desulfurization gypsum (FGDG) has been used for many beneficial purposes such as wall board manufacturing, cement production and as an soil amendment and fertilizer in agricultural practice. Alkaline behavior, high Ca 2+ and SO 42- content of FGDG can be used to stabilize heavy metals in contaminated soils.

The station is equipped with a magnesium-enhanced wet flue gas desulfurization (FGD) system (scrubber) to control SO 2 emissions. In 2000, the scrubber process was modified to accommodate a gypsum ...

Because mining raw gypsum can be an energy-intensive process, pre-consumer recycled gypsum (aka flue gas desulfurization or synthetic gypsum) is often thought to be more sustainable. However, flue gas desulfurization (FGD) gypsum relies on fly ash, a byproduct from burning coal. Fly ash may contain residuals of toxic heavy metals like mercury.

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.

gypsum and minor fillers such as vermiculate and china clay. There may be scope for alternative sources of these fillers. The use of alternative raw materials in plasterboard manufacture Plasterboard manufacturers are increasingly utilising flue gas desulphurisation (FGD) gypsum in their production.
