Analysis of limestone for flue gas desulfurization in a ...

2019-1-31  , the flue exhaust gases from a coal-fired power plant are commonly led through a spray of limestone slurry in a so-called scrubber. The resultant reaction typically captures 90% or more of the SO 2. Approximately 80-85% of worldwide FGD units installed in power plants use wet limestone scrubbing vs. other technologies. What happens to the SO 2
