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.
1. Introduction. Flue gas desulfurization (FGD) involves the removal of sulphur dioxide (SO 2) contained in gases produced by the combustion of fossil fuels such as coal, oil, municipal solid waste and many industrial processes.SO 2 emissions are a primary contributor to acid rain and have been regulated by every industrialized nation in the world (Córdoba, 2015, Dou et al., 2009).
Flue Gas Desulfurization (FGD) residue is produced when SO x and NO x are removed from gases produced during the combustion of coal.
