Conversion of a Wet-Process Flue-Gas Desulfurization Plant from Quicklime (CaO) to Chalk (CaCO_3)

摘要

90% of all large furnaces desulfurize their flue gas by wet scrubbing with lime additives. In particular, high-calcium lime (CaO), hydrated lime (Ca(OH)_2) and limestone (CaCO_3) in ground or lump form are used for this purpose.
