    Abstract: A method for reducing mercury emission and/or re-emission in cleaned flue gas through control of sulfite concentration within a wet flue gas desulfurization (WFGD) system is disclosed. One method for reducing mercury emission and/or re-emission through control of sulfite concentration is to measure the sulfite concentration of an aqueous alkaline slurry used in a WFGD system and comparing the same to a predetermined sulfite concentration value. If the comparison reveals the measured sulfite concentration is above the predetermined values, the amount of oxidation air supplied to the system is increased. If the comparison reveals the measured sulfite concentration is below the predetermined values, the amount of oxidation air supplied to the system is decreased.

    Abstract translation: 公开了一种通过控制湿式烟道气脱硫（WFGD）系统中的亚硫酸盐浓度来减少净化烟气中的汞排放和/或再排放的方法。 通过控制亚硫酸盐浓度来减少汞排放和/或再排放的一种方法是测量WFGD系统中使用的碱性水性浆料的亚硫酸盐浓度，并将其与预定的亚硫酸盐浓度值进行比较。 如果比较显示测得的亚硫酸盐浓度高于预定值，则提供给系统的氧化空气量增加。 如果比较显示测得的亚硫酸盐浓度低于预定值，则减少供给系统的氧化空气量。

    Abstract: A method of scrubbing flue gas includes introducing flue gas comprising an acidic gas through an inlet into a tower; spraying an acid-absorptive fluid into the tower such that the acid-absorptive fluid contacts the flue gas; accumulating the acid-absorptive fluid in a recycle tank portion of the tower; and introducing an oxygen-containing gas into the acid-absorptive fluid in the recycle tank portion of the tower, wherein the oxygen-containing gas is introduced through at least one opening of an aerator, each of the at least one openings are positioned to release the oxygen-containing gas at least at a distance greater than or equal to a predetermined radial distance from the flue gas inlet, the predetermined radial distance being equal to at least 10% of a diameter of the recycle tank portion of the tower.
