The desulfurization gypsum in thermal power plants is mainly produced by the limestone-gypsum wet desulfurization process. The method uses limestone as a desulfurizing agent, and sprays the absorbent slurry into the tower to fully contact and mix with the flue gas, thereby washing the flue gas, then the SO 2 (in the flue gas) reacts with the ...

· Abstract. In this study, the technical feasibility of the mineral carbonation of flue gas desulfurization (FGD) gypsum to sequester CO2 was assessed by considering various reaction parameters. Unlike other natural and industrial materials, FGD gypsum showed very high carbonation reactivity at room temperature and atmospheric pressure.
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". Due to the stringent environmental emissions ...
The chemical structure of coal macerals is usually characterized by the presence of inorganic and organic sulfur. Inorganic sulfur consists mostly of iron sulfides, the so-called "pyritic sulfur," whereas organic sulfur is covalently bound to the carbon atoms of the coal macromolecule. Comminution o …
Bottom ash is a mineral-based by-product arising from the combustion in coal in power plants. In the combustion process, coal particles are blown into a dry furnace at a temperature of around 1,200°C. Depending on its origin, the coal used contains between 64 and 95 percent of carbon and 5 to 35 percent of non-combustible mineral constituents.

Jeri Sullivan Scrubbers can be used to help desulfurize the exhaust from power plants. Desulfurization is the process of removing sulfur from something to prevent contamination. Also known as hydrodesulfurization or HDS, this chemical process reduces the sulfur dioxide emissions and converts them to sulfuric acid. The sulfuric acid is then used in car batteries and fertilizer.
Removal of Sulfur Dioxide is called as Flue-gas Desulphurization (FGD). As the name defines, it is the technology used to remove gaseous pollutants viz. SO2 from exhaust flue gases generated in furnaces,boilers, and other industrial processes due to thermal processing, treatment, and combustion. This system consists of the equipment''s that ...
