ABSTRACT:
In a flue gas desulfurization process wherein, when sulfur oxide-containing exhaust gas is treated with an absorbing solution containing a calcium compound, an oxygen-containing gas is passed through the absorbing solution and the flow rate of the oxygen-containing gas is controlled by detecting the oxidation-reduction potential of the absorbing solution continuously, an oxidation controlling method which comprises detecting a first deviation signal between the oxidation-reduction potential of the absorbing solution and the oxidation-reduction potential of the absorbing solution in a completely oxidized state and controlling the flow rate of the oxygen-containing gas in response to a second deviation signal between the first deviation signal and a preset oxidation-reduction potential deviation value.
