In conventional coal plants, the most common form of sulfur dioxide control is through the use of scrubbers. To remove the SO 2, the exhaust from a coalfired power plant is passed through a mixture of lime or limestone and water, which absorbs the SO 2 before the exhaust gas is released through the smokestack. Scrubbers can reduce sulfur emissions by up to 90 percent, but smaller particulates are .
