Abstract | The report describes the development of continuous onstream analytical methods to optimize and control wet limestone and dolomite scrubbing processes. Emphasis was on developing continuous on-line methods for slurry sampling and separation that do not disturb the chemical steady state condition. Sampling methods were developed for a 30-second phase separation and instrumentation was identified for 2-minute analysis of sulfur, calcium, magnesium, and iron in the solid phase, and acidity, sulfite, sulfate, calcium, magnesium, and carbonate in the liquid phase. A mobile laboratory was designed and outfitted for field characterization of wet scrubbing flue gas desulfurization (FGD) process streams. Evaluation measurement techniques used to characterize five alternative FGD processes resulted in recommended analysis methods for the ammonia, double alkali, Mag-Ox, Stone and Webster/Ionics, and Wellman-Lord processes. |
