FLUE GAS DESULFURIZATION (SCRUBBING) In a flue gas desulfurization (FGD) system, sulphur compounds are removed from the exhaust emissions of fossil-fuelled power stations. This is done by means of an industrial process through the addition of absorbents. Flue gas desulfurization can remove up to 95 % of the sulphur dioxide from the flue gas.
Flue gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.

The limestone-gypsum wet desulfurization system mainly involves the absorption section and the oxidation section.
During the first years of the 1980s, the absorber sump of an flue gas desulfurization plant was generally equipped with a sparger grid to inject the oxidation air into the process. The little outlets of the pipes were easily plugged by the solids and led to significant investment, repair and maintenance costs. ... and then oxidized with ...
The commercial plant growth materials are widely used in a soil-less culture because of their high hardness and ease of use. However, the disadvantages of commercial plant growth materials are expensive because of low density and high pH value. The objective of this research is to produce ceramic plant growth material (CPGM) from leonardite and flue gas desulfurization (FGD) …
This research aims to study the utilization of waste from power plants, construction and demolition, and agriculture by varying the ratios of flue-gas desulfurization (FGD) gypsum, construction and demolition waste (CDW), and oil palm trunks (OPT) in concrete production.

Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO2) gas, is the primary contribution coal makes to FGD gypsum. Utilities that produce panel-grade synthetic gypsum beneficially reuse FGD sludge …
