Flue-gas desulfurization

Sulfur dioxide may also be removed by dry desulfurisation by injection limestone slurry into the flue gas before the particle filtration. It is most notable as the product of flue-gas desulfurization. This improvement resulted in part from flue-gas desulfurization, a technology that enables SO 2 to be chemically bound in power plants burning sulfur-containing coal or oil.

Status of Flue Gas Desulphurisation (FGD) systems from

Mar 15, 2015 · 1. Introduction. The term Flue Gas Desulphurisation (FGD) system has traditionally referred to wet scrubbers that remove SO 2 emissions from large electric utility boilers. The FGD systems emerged in the industrial field of the coal-fired power plants and on some industrial processes in the early 1970s in United States (US) and Japan, and expanded rapidly in the 1980s in Europe.

US4804523A - Use of seawater in flue gas desulfurization

For a typical coal-fired power station, flue-gas desulfurization (FGD) may remove 90 percent or more of the SO 2 in the flue gases. History. Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years. Early ideas for flue gas desulfurization were established in England around 1850.

ing seawater for flue gas desulfuriza-tion. In most cases these processes rely on the natural alkalinity of seawater for its desulfurizing properties. Normally seawater has a pH of 8.0 to 8.3 and an alkalinity of 2.2 to 2.4 milli-equivalents per liter. Using seawater alkalinity alone for desulfurizing flue gas requires a very large flow of seawater to the
