| Abstract |
The report gives results of a study to develop appropriate sampling and analytical methods to be used at EPA's test facility at Shawnee. Three problem areas developed in analyzing the thermodynamically unstable slurry streams encountered in lime/limestone-based SO2 wet scrubbing processes: sampling, sample handling, and chemical analysis. Positive-pressure filtration was found to lower the mass transfer phenomena during the filtration step to an acceptable level. Quenching of the filtered liquid was chosen to avoid changing sample composition. Two sets of analytical methods were selected for application at Shawnee: the back-up methods are based on atomic absorption and wet chemical procedures; and the rapid field methods are based on X-ray fluorescence, atomic absorption, and wet chemical analysis. The X-ray fluorescence spectrometer was automated by interfacing it with a NOVA 1200 minicomputer. Additional peripheral devices have the function of processing all raw data. The raw data are input to the system with a card reader, a teletype, or a CRT. The final results are stored on a magnetic tape. A hard copy is provided by a printer. |

This study was carried out to develop appropriate sampling and analytical methods to be used at OAP's test facility at Shawnee. The three probelm areas encountered in analyzing thermodynamically unstable slurry streams as encountered in lime/limestone based SOb2s wet scrubbing processes are sampling, sample handling and chemical analysis. A positive pressure filtration was found to minimize the mass transfer phenomena during the filtration step to an acceptable level. Quenching of th filtered liquid was chosen to avoid change in sample composition. Two sets of analytical methods were selected for application at Shawnee. The back-up methods are based on atomic absorption and wet chemical procedures. The rapid field methods are based on X-ray fluorescence, atomic absorption, and wet chemical analyses. The X-ray fluorescence spectrometer was automated by interfacing it with a NOVA 1200 minicomputer. Additional peripheral devices have the function of processing all raw data.
