limestone used in coal power plants

limestone used in coal power plants, the flue exhaust from a coal-fired power plant is commonly bubbled through a mixture of lime or limestone and water. The resultant reaction typically captures 95 % or more of the SO 2. Approximately 80-85 % of worldwide FGD units installed in power plants use wet limestone scrubbing vs. other technologies.
