Thermogravimetry simplifies scrubber solids analysis
- Burns and McDonnell Engineering of Kansas City, MO (United States)
Flue-gas desulfurization (FGD) system (FGDS) reliability and performance have improved over the years and so have the techniques for analyzing scrubber liquors and solids. Accurate analyses of scrubber reagents and reactants are important to determine FGDS efficiency, slurry scaling potential and other operational factors. For those who may not be familiar with the technique, thermogravimetry (TG) is an excellent method for obtaining fast but meaningful determinations of FGD solids. Prior to the use of thermogravimetry, lab personnel had to use time-consuming, wet chemistry techniques for FGDS solids analyses. Because a TG analysis (TGA) requires little sample preparation other than drying, results can be obtained fairly rapidly. TGA reduced, by more than half, the amount of time lab chemists needed to perform daily solids analyses, and it improved accuracy of the results.
