摘要： There is provided a method for flue gas desulfurization which is capable of conducting minute control of oxidation and which is capable of maintaining the concentration of sulfurous acid in an absorbent liquid within a proper range in a highly reliable and efficient manner, even in the case where an abrupt change occurs in the operational conditions of the system. In the method for controlling the oxidation in flue gas desulfurization, the value of proportional sensitivity K in the feed back control process, which is based primarily on the oxidation-reduction potential, is increased depending on the deviation .epsilon. in a region where the detected oxidation reduction potential value PN is below the target oxidation reduction potential value SN in correspondence with the characteristic change of the oxidation-reduction potential against the concentration of sulfurous acid.

摘要： In a flue gas desulfurization process based on the wet lime-gypsum method, the controlled oxidation of sulfites, by comparison of the redox potential of an absorbing fluid in a sample tank and the redox potential of the absorbing fluid in a completely oxidized state in a reference tank, and adjustment of the rate of air flow through the absorbing fluid, is improved by removing peroxides from the absorbing fluid in the reference tank before passing air therethrough to effect oxidization to a completely oxidized state. The method avoids instability due to the presence of peroxides in the absorbing fluid.
