Abstract
A method and apparatus for operating a limestone wet scrubbing flue gas desulfurization apparatus comprises first and second pH measuring devices connected respectively to a recirculation line in the scrubber and above the liquid holdup tray in the scrubber. The difference in the pH values measured at these two locations in the system is used to adjust the amount of air supplied to the sump or reaction tank of the scrubber to maximize oxidation in the scrubber and to avoid wasted airflow.
