Limestone-gypsum flue gas desulfurization process is the world's most widely used FGD technology. About 90% of Japan, Germany, and the U.S. power plants use gypsum desulfurization process, which is wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime. Joyal has been engaged in limestone grinding for more than 30 years.

Chemical grade limestone plays a critical role of keeping coal-fired boilers in environmental compliance. It is used in wet flue gas desulphurization (FGD) to reduce sulfur dioxide and other acid gases. This product is also injected into the boiler for additional reduction of acid gases and heavy metals. Additionally, limestone can be added to the coal belt to reduce arsenic and other heavy ...
