Sampling and analysis of natural gas trace constituents

Description: Major and minor components of natural gas are routinely analyzed by gas chromatography (GC), using a thermal conductivity (TC). The best results obtained by these methods can report no better than 0.01 mole percent of each measured component. Even the extended method of analysis by flame ionization detector (FID) can only improve on the detection limit of hydrocarbons. The gas industry needs better information on all trace constituents of natural gas, whether native or inadvertently added durin… more

Effects of coal-derived trace species on the performance of carbonate fuel cells

Description: NH{sub 3} Cd, Hg, and Sn have no noticeable effects on carbonate fuel cell performance. Zn and Pb (the latter in the presence of Se) had minor effects, while the interactions of H{sub 2}S, HC{ell}, H{sub 2}Se and As are more significant. Because H{sub 2}S had already been extensively investigated earlier by various groups, the focus in this study was centered on the latter three elements. It appears that HC{ell}, H{sub 2}Se, and As need to be limited to sub-ppM levels in a manner similar to H{s… more

Anionic sorbents for arsenic and technetium species.

Description: Two sorbents, zirconium coated zeolite and magnesium hydroxide, were tested for their effectiveness in removing arsenic from Albuquerque municipal water. Results for the zirconium coated zeolite indicate that phosphate present in the water interfered with the sorption of arsenic. Additionally, there was a large quantity of iron and copper present in the water, corrosion products from the piping system, which may have interfered with the uptake of arsenic by the sorbent. Magnesium hydroxide has … more

THE USE OF COAL COMBUSTION BY-PRODUCTS FOR IN SITU TREATMENT OF ACID MINE DRAINAGE

Description: In 1994 a demonstration project was undertaken to investigate the effectiveness of using CCBs for the in situ treatment of acidic mine water. Actual injection of alkaline material was performed in 1997 with initial positive results; however, the amount of alkalinity added to the system was limited and resulted in short duration treatment. In 1999, a CBRC grant was awarded to further investigate the effectiveness of alkaline injection technology (AIT). Funds were released in fall 2001. In Decemb… more
