Desulfurization

Desulfurization is removal of sulfur or sulfur derivative compounds commonly from flue gas or fuels. The most usually needed desulfurization is in natural gas and for coal, oil, and flue gas.

On the synergistic modulation of Ca (OH)2

Taking the industrial desulfurization as an application scenario, high-performance Ca(OH) 2 can be used for effective SO 2 removal, which is a Ca(OH) 2 structure-sensitive process. The flue gas with SO 2 concentration of 50–500 mg/m 3, especially emitted from non-electric industries such as coking, iron, and steel production, accounts for more than 30 % of China's total SO 2 …

Desulphurization mechanism and engineering practice …

The specic surface area, pore distribution, and other physicochemical parameters were analyzed by XRD and SEM, which explained the changes of products and carbide slag before and after desulfurization. The test results show that carbide slag and limestone have almost the same desulfurization eect. The kinetics of carbide slag desulfurization ...

Environmental Science Advances

1. Introduction Flue gas desulfurization gypsum is produced from the capture of SO 2 in the ue gas of fossil fuel combustion using Ca-based absorbents.1–3 Limestone or lime slurry is a widely used Ca-based absorbent.4 This desulfurization process is as follows:5,6 SO2 +H2O = 2H + +SO 3 2− (1) Ca2+ +SO 3 2− = CaSO 3 (2) 1/2O2 + CaSO3 ...
