| Abstract |
The report gives results of a study to determine the applicability of chloride and pH electrodes in automated control systems. It included a survey of chloride and pH electrodes in different flue gas desulfurization (FGD) systems and an evaluation of an industrial pH electrode system. The survey showed that chloride ion measurements were necessary only where high chloride values correspond with FGD unit corrosion and when chloride values were used as correction factors in pH calculations. Chloride ion measurements are unnecessary for most of the surveyed companies. All surveyed companies use pH measurements to control scaling or to attain optimum performance in FGD units. The most common pH electrode problem was residue buildup (scaling) around the electrode, caused by the use of non-self-cleaning (standard) pH electrodes. The performance of self-cleaning and standard industrial pH electrodes was evaluated. |
