Abstract
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.
