Sulfur dioxide control technologies attempt to reduce SO 2 emissions through technologies utilizing conventional limestone and gypsum in flue gas desulfurization (FGD) systems. The integration of the materialhandling systems for FGD projects with the existing coalhandling plant is the key to success.
The earliest application of flue gas desulphurisation (FGD) at coalfired power plants can be traced back to the early 1930s in England. The application of FGD technologies in earnest for the control of SO 2emissions began in the late 1960s and early 1970s in Japan and the USA, and this was followed by Western Europe in the 1980s.
The Eurosilo Gypsum silo is the answer to all of your storage space problems. The FGDGypsum Silo incorporates three vital functions at the smallest possible footprint. Dewatering, storage and loadout are all located in one fully automated silo system for the most cost effective solution.
The FGD technologies would be less of a financial burden if successful commercial uses were developed for the gypsumrich byproducts of the wet limestone scrubbing. The degree to which FGDgypsum is commercially used depends on its quality. Currently, highquality FGDgypsum with purity greater than 94% is used mainly to manufacture
