Flue Gas Limestone

Limestone, constituted mainly by calcium carbonate, is widely utilized in Flue Gas Desulfurization (FGD) processes because of the ability to capture the sulfur as sulfate salts. The evaluation of limestone reactivity is therefore a key aspect for FGD process design and plant operation.

Flue Gas Scrubbing with Limestone Slurry A. Saleem Ontario Hydro A scrubbing process for flue gas desulfurization, based upon naturally occurring carbonate rocks, has been developed from laboratory to pilot plant scale. Calcitic limestones are better sulfur dioxide absorbents than dolomitic ones when used in the slurry form. The process was ...

Wet flue gas desulphurisation is usually based on the use of calcareous absorbents (for example limestone, calcium hydrate, quicklime or chalk). Industrially, the use of limestone as an absorbent has prevailed in the area of power stations. The limestone-gypsum method produces gypsum as an end product, which is marketable for industrial re-use.

The operators of EPA’s 10-M pilot limestone scrubbing system (at TVA’s Shawnee Station) have developed a mode of operation on flue gas high in sulfur dioxide and HC1 in the closed loop mode. The liquor is supersaturated in respect to calcium sulfate and high in chloride ion content.

FLUE GAS DESULFURIZATION SYSTEMS SINCE 1850 Research, Development and Demonstration Methods for removing sulfur dioxide (SO2) from boiler and furnace exhaust gases have been studied through-out the twentieth century. ... limestone slurries, which had received far less attention in the past.

Chemical grade limestone plays a critical role of keeping coal-fired boilers in environmental compliance. It is used in wet flue gas desulphurization (FGD) to reduce sulfur dioxide and other acid gases. This product is also injected into the boiler for additional reduction of acid gases and heavy metals. Additionally, limestone can be added to the coal belt to reduce arsenic and other heavy ...

31-08-2006· New flue gas desulfurization (FGD) units are being installed at utilities in many parts of the U.S. and a large percentage of the new scrubbers are of the wet limestone type.

A flue gas desulfurization (FGD) processing unit, generally known as a scrubber, eliminates sulfur dioxide (SO 2) from the exhaust flue gases in power plants in which coal is burnt. Airborne SO 2 forms sulfuric acid (H 2 SO 4 ) by oxidizing within airborne water droplets, resulting in “acid rain”.
