1. A method of providing an indication of oxidation percentage in a wet scrubber comprising supplying air into the scrubber, supplying flue gas through a flue gas inlet to the scrubber from which sulfur is to be removed, spraying an absorber slurry from above the flue gas inlet down into a sump or reaction tank below the flue gas inlet, recirculating the slurry from the sump to the spray through a recirculating line, the method further comprising the steps of:

  • measuring the pH of the slurry in the recirculating line to obtain a first pH measurement;

    measuring the pH of the slurry above the flue gas inlet to obtain a second pH measurement;

    calculating the difference between the first and second pH measurements; and

    using the difference as an indication of oxidation percentage taking Place within the scrubber.
