Use of limestone for SO2 removal from flue gas in

15-10-2000  Hydrated lime is normally used as SO 2 sorbent in spray dry scrubbers, whereas limestone is considered unreactive under conditions prevailing in such a system. However, limestone is more easily available and several times cheaper than hydrated lime. We tried to use limestone to remove SO 2 from flue gas in the semidry FGD process with a powder-particle spouted bed.

Flue-gas desulfurization - Wikipedia

About 45% of the FGD capacity was in the U.S., 24% in Germany, 11% in Japan, and 20% in various other countries. Approximately 79% of the units, representing about 199 gigawatts of capacity, were using lime or limestone wet scrubbing. About 18% (or 25 gigawatts) utilized spray-dry scrubbers or sorbent injection systems. FGD on ships

Flue-gas desulfurization ~ Power Plants

04-10-2009  Flue gas desulfurization (FGD) is a technology used to remove sulfur dioxide (SO 2) from the exhaust flue gases of fossil fuel power plants. Fossil fuel power plants burn coal or oil to produce steam for steam turbines, which in turn drive electricity generators. Sulfur dioxide is one of the elements forming acid rain.

About Flue Gas Desulfurization - News -

The most commonly used alkaline substances in flue gas desulfurization are limestone (calcium carbonate, CaCO3), quicklime (calcium oxide, CaO) and hydrated lime (calcium hydroxide, Ca (OH) 2). Limestone is relatively cheap because of its abundant production. Quick lime and hydrated lime are made from limestone by heating.
