ABSTRACT:
Sulfur dioxide is removed from flue gases resulting from combustion of sulfur-containing coal in a coal combustion unit by contacting the gases in the coal combustion unit with hydrated lime containing sugars and then adding an aqueous media, preferably containing an alkali metal compound, to the gases in ductwork leading from the coal combustion unit to an electrostatic precipitator.
