In situ optical measurements of hydrofluoric acid aerosols
- INSITEC, San Ramon, CA (USA)
HF aerosol measurements were obtained in a specially developed flow chamber with a cross-section of 8 {times} 16 feet, and approximately 140 feet long. The primary objective was to determine the extent of HF aerosol mist formation in a potential accidental release of HF. A newly developed in situ optical instrument (PCSV-P) was used to obtain on-line measurements of the aerosol. A total of 86 usable aerosol data sets were obtained during the test period. As many as 10 data sets were acquired for an 11 minute duration HF release. Briefly summarizing the results, the PCSV-P measured predominately submicron aerosols at the exit of the sharp-edged orifice. The aerosol then grew to larger particles at the outlet of the flow chamber. This result points to the formation of an aerosol through vaporization-condensation as opposed to a conventional shear spray. Temperature, humidity, release pressure, radial position in the plume, and type of acid did not appear to have an significant effect in the measured size distributions for the range of conditions investigated. 7 refs., 23 figs., 2 tabs.
