Abstract
Methods and systems for control and adjustment of the feed rate of mercury reemission control additives (MECA) to a wet flue gas desulfurization system. Predetermined sulfite concentration values are compared to actual sulfite concentrations measured in the scrubber liquid. The MECA feed to the recirculating scrubber liquor is then adjusted and regulated as a result of such comparisons.
