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.

Process for removing sulphur dioxide from flue gas

A scrubbing tower and process for flue-gas desulfurization uses a device for introducing additives like lime and limestone to the reaction zone of the scrubber by feeding those additives to a recirculating system recirculating the liquid through the sump. The recirculating system can also be used to withdraw the suspension from the column whose sump is cylindrical with a flat bottom. Recirculated liquid is introduced close to this bottom by the recirculating pump.
