OverviewHistoryMethodsSulfuric acid mist formationFGD chemistryFacts and statisticsAlternative methods of reducing sulfur dioxide emissionsSee also

Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years. Early ideas for flue gas desulfurization were established in England around 1850. With the construction of large-scale power plants in England in the 1920s, the problems associated with large volumes of SO2 from a single site began to concern the public. The SO 2 emissions problem did not receive much attention until 1929, when the House of Lords upheld th
