Measurements of potential atmospheric pollutants in off-gases from the Lawrence Livermore National Laboratory's 6-tonne retort, Experiment L-3
1982
Total sulfur, hydrogen sulfide, hydrocarbons, and nitrogen in the off-gases from the Lawrence Livermore National Laboratory's 6-tonne/day Rubble In Situ Extraction Simulation facility were measured with a series of on-line, gas-monitoring instruments and gas indicator tubes. In addition by using instrumental neutron activation analysis after collection in adsorbent traps or in filter and impactor samplers, the concentrations of several trace elements in the off-gas vapors and in aerosol mists were determined. The concentrations of hydrocarbons in the vapor and in the product oil were determined either by on-line gas chromatography and off-line gas chromatography, or off-line gas chromatography coupled with mass spectroscopy. The assembled data are used to estimate production factors for potential pollutants for use in developing emission control options and assessment of air quality.
