用水溶液从废气中清除二氧化硫,都产出一种或多种含硫产品。这些方法基于二氧化硫为水溶液(或悬浮液)所吸收,随即进行化学反应。这些方法有溶液可再生的和不可再生的。再生系统产出SO_2、硫酸或单体硫,并回收吸收剂。非再生系统的吸收剂不再生回收, Sulfur dioxide is scavenged from the exhaust gas with an aqueous solution to produce one or more sulfur-containing products. These methods are based on the absorption of sulfur dioxide as an aqueous solution (or suspension), followed by a chemical reaction. These methods have solutions that are renewable and non-renewable. The regeneration system produces SO 2, sulfuric acid or monomeric sulfur and recovers the absorbent. Non-regenerative absorbent systems are not regenerated,
