2019-1-31  During the combustion process the sulfur in the coal combines with oxygen in the air to form SO 2. To remove the SO 2, 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%
