ABSTRACT:
A scrubber for removing sulfur compounds from a gas, particularly a flue gas of a power plant boiler combustion chamber, comprises spray devices for washing the gas with a liquid containing a sulfur compound binding agent. The sump is provided with a partition formed by an array of oxygen ducts which divides the sump into an upper oxidation zone and a lower reaction zone. An additive is introduced into the reaction zone to induce the precipitation of calcium sulfite in the sump product.
