  • Determination of Flue Gas Desulfurization in a Power Plant ...

    In order to eliminate the SO 2, the flue exhaust gases from a coal-fired power plant are usually passed through a spray of limestone slurry in the scrubber. The resultant reaction typically traps over 90% of the SO 2. Nearly 80%–85% of the global FGD units set up in power plants use wet limestone scrubbing compared to other technologies.
