Abstract
An on-line control and monitoring system for automatically and continuously analyzing key process indicators in a wet lime/limestone flue gas desulfurization process is provided. The on-line control and monitoring system obtains a slurry and/or a slurry flitrate which is directed at selected fluid flow rates to one or more analytical devices each selected to analyze a flue gas desulfurization process indicator. Data is provided to a data acquisition system which processes the analysis results from the analytical devices and provides flue gas desulfurization process control information. This on-line monitoring and control system can be used to monitor and control the addition rate of performance enhancement additives such as organic acids, thiosulfate, oxidation air and the like.
