Abstract. A flue gas desulfurization process capable of producing a high purity gypsum and also making equipment employed as minimum as possible is provided, which process comprises the steps of cooling and dedusting flue gas containing SO /SUB x/ ; contacting the cooled gas with a slurry containing limestone to remove SO /SUB x/ by absorption and also form CaSO/sub 3/; controlling the pH of
The flue gas flows into the absorber above the fluid level and then through the absorption zone, which comprises overlapping spraying levels and a mist eliminator. The limestone slurry sucked from the absorber sump is finely sprayed cocurrently and countercurrently to the flue gas
The limestonegypsum wet flue gas desulfurization (WFGD) process has a significant influence on the emission characteristics of soluble ions in particulates. In this study, a simulated limestonegypsum WFGD platform was used to study the emission characteristics of watersoluble ions in
Limestonegypsum desulfurization process is one of the most widely used desulfurization technologies in the world. About 90% thermal power plants in Japan, Germany, and the United States adopted this technology for the flue gas desulfurization . Part2 2. Working Principle Limestone is used as the desulfurization absorbent. Limestone is crushed

Flue Gas Desulfurization: The State of the Art [J] and specifically wet limestone FGD, gypsum produced from the MEL process may be lighter.
In some cases, wet flue gas desulfurization (WFGD) systems installed in coal fired power plants to control SO 2 emissions have been used to decrease mercury emissions [37]. In such systems, SO 2 usually reacts with the limestone slurry to produce insoluble gypsum.
Ducon produces highefficiency absorbers capable of up to 98% sulfur dioxide removal with limestone. All designs consume minimal power and limestone.

What is Flue Gas Desulfurization (FGD)? FGD is a set of technologies used to remove Sulfur Dioxide (SO2) from exhaust flue gases in coal, oilfired, and waste toenergy power stations. SO2 is a pollutant/irritant in air and a major contributor in the creation of acid rain. SO2 emissions are subject to strict environmental protection regulations.
