Trace Gas, Product Water, and Particulate Characterization for Rocky Mountain 1 UCG Project. Underground Coal Gasification Test, Hanna, Wyoming

摘要

Rocky Mountain 1 Underground Coal Gasification (UCG) Test product gas streams were sampled for liquid, gaseous, and solid products. Water quality analyses indicate that ammonium and bicarbonate ions were the most abundant. Of the trace elements only aluminum, boron, mercury, and selenium were present in quantities above regulatory limits. The major organic components were phenolic compounds. Pyrene was the highest molecular weight aromatic compound detected. The major gaseous sulfur species was hydrogen sulfide; ammonia was the major gaseous nitrogen species; and benzene was the most prevalent hydrocarbon in the gas stream. Large variations in particulate loading and size indicate that cleanup systems would have to handle a wide range of sizes and amounts of particulates.
