A sampling and analysis research program was conducted at the Paraho oil shale retorting demonstration site at Anvil Points, Colorado. The overall objective of the test program was to obtain preliminary quantitative and qualitative measurements of air, water, and solid compositions, and to gain experience that would lead to improved sampling procedures and the determination of priorities for sampling and analysis of shale oil recovery operations. Selection of sample locations was based on need for information on process streams relative to emissions and effluents expected in a full-scale plant. Samples taken included the recycle gases (H2S, SO2, NOx, NH3, and trace organics), recycle condensate, product oil/water, processed shale discharged from the retorts, and dust in the vicinity of crushing, screening, and conveying equipment. A variety of laboratory analysis methods were used, including wet chemical analysis, spark source mass spectrometry, high pressure liquid chromatography, thin layer chromatography, gel permeation chromatography, and gas chromatography/mass spectrometry methods (GC/MS). Condensate water inorganic analyses were done for calcium, magnesium, sodium and potassium salts, ammonia, gross parameters, and trace elements. Condensate and product water samples were also analyzed for organic neutrals (particularly aromatics), organic acids, and organic bases. Elemental determinations of both retorted shale and raw shale particulates were made.
