Clean Coal Technology

To remove the SO 2 the exhaust from a coal-fired 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 less likely to be absorbed by the limestone and can...
