Description:
The report gives results of a program of over 60 tasks involving the evaluation, development, testing, and field adaptation of measurement techniques for elemental analysis and inorganic compound identification in process and effluent streams. Procedures for particulate sampling at the inlet and outlet of FGD systems were developed. Methods for H2SO4 sampling in flue gas streams were developed based on the controlled condensation of H2SO4 vapor (a manual procedure was used as the basis for an automated H2SO4 monitoring instrument that was built and tested). Two procedure manuals were written for reduced and oxidized inorganic species. The reduced species manual detailed GC and GC/MS procedures for identifying organometallic compounds as well as homologous series such as RSH and RNH. The oxidized species were identified using an integrated series of analytical methods such as AAS, ICAP, XRD, FTIR, ESCA, and SEM-EDX. The procedures developed, applied to samples from several EPA programs, showed that the analysis scheme is applicable to most solid samples from combustion sources. Ion chromatographic procedures were also developed for analyzing FGD system slurry streams. The use of pH and chloride electrodes for controlling FGD systems was investigated. The methodology for coal flow monitors was reviewed.
