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.
摘要翻译：一种通过在含水吸收剂中同时吸收和氧化从烟道气中除去二氧化硫的方法。提供用于二氧化硫的水性液体吸收剂的封闭体，并且将烟道气喷射到液体吸收剂的上部以形成其第一区域。将含氧气体引入到液体吸收剂的下部，以形成液体吸收剂的第二区域，该第二区域位于液体吸收剂的第一区域之下，并且其表观密度高于第一区域的表观密度。来自第二区域的含氧吸收剂循环到靠近烟道气引入点的第一区域，并且与液体吸收剂中的二氧化硫反应的碱性物质被引入液体吸收剂体内，从而将二氧化硫固定在液体吸收剂为硫酸盐形式。硫酸盐随后从水性液体吸收剂的体内除去。根据本发明的方法可以在紧凑的装置中进行，并实现高脱硫率。
