摘要： A method for removing sulfur dioxide from flue gases by simultaneous absorption and oxidation in an aqueous absorbent. An enclosed body of an aqueous liquid absorbent for the sulfur dioxide is provided and the flue gas is sparged into an upper portion of the liquid absorbent to form a first zone thereof. An oxygen-containing gas is introduced into a lower portion of the liquid absorbent to form a second zone of the liquid absorbent that is below the first zone of the liquid absorbent and which has an apparent density that is higher than that of the first zone. The oxygen-containing absorbent from the second zone is circulated to the first zone near the point of the flue gas introduction and an alkaline material reactive with the sulfur dioxide in the liquid absorbent is introduced into the body of liquid absorbent thereby fixing the sulfur dioxide in the liquid absorbent in the form of a sulfate. The sulfate is subsequently removed from the body of aqueous liquid absorbent. The method according to the invention can be carried out in a compact apparatus and achieves a high rate of desulfurization.
