Title:
EQUIPMENT FOR THE DESULFURIZATION OF FLUE GAS WITH SEAWATER AND PROCESS FOR TREATMENT OF THE SEAWATER USED IN THE DESUFURIZATION
Document Type and Number:
WIPO Patent Application WO/2010/131327
Kind Code:
A1
Abstract:
The first equipment (10-1) for the desulfurization with seawater according to the invention has both a flue gas desulfurization /absorption tower (13) for bringing the sulfur-containing substances contained in flue gas (11) into contact with absorber seawater (12A) (which is part of seawater (12)) and thereby purifying the flue gas, and a dilution/mixing tank (16) which is provided under the flue gas desulfurization/absorption tower (13) integrally therewith and in which seawater (14A) containing sulfur-containing substances (which is generated in the desulfurization/absorption tower (13) by bringing the sulfur -containing substances contained in flue gas (11) into contact with absorber seawater (12A) and thereby desulfurizing the flue gas with the absorber seawater (12A)) is mixed and diluted with diluent seawater (12B) which is fed into the body (15). Further, the equipment (10-1) also has a gas residence section (20A) equipped with both a cover (18) which is provided on the lower end side of the side wall (17) of the flue gas desulfurization /absorption tower (13) along the longer direction of the dilution/mixing tank (16) in such a way that the cover (18) extends over the dilution/mixing tank (16), and a first weir (19) which hangs down from the back side of the cover (18) in such a way that the end of the weir (19) is buried under the water surface in the dilution/mixing tank (16).
