Abstract

Sulfur dioxide is removed from flue gas by scrubbing with sea water and aeration of the sump to convert the removed sulfur dioxide into bisulfate with neutralization in a reaction basin subsequently forming sulfate. The neutralization is carried out by the treatment of sea water and a pH of 4 to 5 and preferably 4.15 to 4.5 is maintained in the liquid phase removed from the sump by controlled recycling of the sump liquid to the absorption zone or addition of further quantities of sea water to the column.
