The Technology of Limestone Flue GAS Desulfurization. Limestone or lime is used as desulfurization absorbent, limestone is broken and mixed with water, then ground into powder to form absorbent slurry (when lime is used as absorbent, lime powder is digested and mixed with water to make absorbent slurry). In the absorber, SO2 in flue gas reacts ...
Explanation of Effect of Slurry Density on Limestone Utilization Maintaining pH and SO 2 removal requires a specific limestone loading (g-limestone/L-slurry) level for the system. At low density (low concentration of solids in the slurry), a higher concentration of the solids will be limestone. Therefore limestone utilization will be lower.

Density of Limestone. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume.It is an intensive property, which is mathematically defined as mass divided by volume m/V In words, the density () of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance.

In order to eliminate the SO 2, the flue exhaust gases from a coal-fired power plant are usually passed through a spray of limestone slurry in the scrubber. The resultant reaction typically traps over 90% of the SO 2. Nearly 80%85% of the global FGD units set up in power plants use wet limestone scrubbing compared to other technologies.
In a wet limestone FGD (wFGD) unit, gases are treated with limestone slurry, which is sprayed on the gas in an absorber unit. Gypsum, which can be sold commercially, is produced as a by-product. Approximately 85 percent of the scrubbers installed in the United States are wet scrubbers ( USEPA 2004 ). 11 Another rapidly expanding technology is ...

However, dry or semi-dry FGD systems are usually exhibit lower SO2 removal efficiencies because of the short contact time between the flue gas and the sorbent (Ersoy-Meriboyu, 1999). Thus, several wet FGD systems have been developed and are in commercial use, including a variety of scrubbing processes involving limestone or
Dec 01, 2019 The flue gas desulfurization (FGD) processes can be separated into two main categories once-through and regenerable processes, depending on how the sorbent is treated after SO 2 adsorption (Srivastava and Jozewicz, 2001).Once-through, or non-regenerable, processes utilize the sorbent as a beneficial by-product or dispose of it as waste.
