    Abstract: This invention is a combination process for removal of sulfur oxides (SOx) from gases containing both the SOx and oxygen (106). The fluid used to remove the SOx contains sulfuric acid and bromine. The SOx is converted to sulfuric acid and the bromine is thereafter converted to hydrobromic acid. The hydrobromic acid is concentrated and catalytically converted to bromine for ultimate recycling to the SOx removal step (132). The SOx is finally recovered as a strong sulfuric acid (104).

    Abstract translation: 本发明是从含有SO x和氧(106)的气体中除去硫氧化物(SOx)的组合方法。 用于除去SOx的流体含有硫酸和溴。 将SO x转化为硫酸,然后将溴转化为氢溴酸。 将氢溴酸浓缩并催化转化成溴,以最终循环至SO x去除步骤(132)。 SO x最终作为强硫酸回收(104)。
