New flue gas desulfuriation FGD units are being installed at utilities in many parts of the U.S. and a large percentage of the new scrubbers are of the wet limestone type. Although wet limestone scrubbing is a well-developed technology, it may be unfamiliar to employees at plants that have previously not required scrubbers. This article provides a primer in the process.Get A Quote
Cement Mills - complete Process design with filtercyclone separation.. Limestone grinding for Flue Gas desulphuriation system in power plants.. projects throughout the world for cement and mineral processing industry from start to finish. More details.
The calcium carbonate CaCO3 in limestone is only slightly soluble in water, but in the presence of acid, it reacts much more vigorously. It is the acid generated by absorption of the SO2 into the liquid that drives the limestone dissolution process.
The wet limestone gypsum process uses limestone as an absorbent for the desulphuriation of flue gases and produces gypsum that is suitable for industrial use as an end product. The flue gases coming from boiler are directed into the absorber where the pollutants SO 2, HCl, HF are removed before flue gas is released into the atmosphere through.
The initial reaction products, calcium and sulfite ions, will by themselves precipitate as a hemihydrate and where water is actually contained in the crystal lattice of the scrubber by-product.
However, oxygen in the flue gas has a major impact on chemistry and, in particular, on by-product formation. Aqueous bisulfite and sulfite ions react with oxygen to produce sulfate ions SO4-2.

CL Attritors Limestone Grinding Mill Union. Stirred Vertical Ball Mill Limestone Grinding System. The economical CL Attritor Stirred Vertical Ball Mill is used for wet grinding limestone for flue gas desulphuriation. The process uses limestone feed stock of approximately 6mm in sie and wet grinds the limestone to 95 minus 325 mesh.
Environmental protection is one of the most important topics in the 21st century. In recent years, with the developmentof the global economy, thermal power plants have sprung up, and coal combustion emissions of large amounts of SO2, NOxand CO2, resulting in worldwide acid rain, hae and other atmospheric environmental pollution problems are more serious,greatly Endanger our living environment. Therefore, to increase the thermal power plant on the SO2 control efforts isparticularly important.
In the combustion of coal burning a certain proportion of limestone powder, after a series of chemical reactions, canachieve desulfuriation effect.
Kefid after years of research and use, developed desulfuriation milling equipment and technology, high sulfur coal desulfuriationrate can be more than 90, desulfuriation rate of low sulfur coal can be more than 95.
APPLICATIONS Glass fiber industry, coal industry, chemical industry, and for large scale powder making andnon mental mine industry.
