Trace element chemistry of coal bed natural gas produced water in the Powder River Basin, Wyoming.
Coal bed natural gas (CBNG) produced water is usually disposed into nearby constructed disposal ponds. Geochemistry of produced water, particularly trace elements interacting with a semiarid environment, is not clearly understood. The objective of this study was to collect produced water samples at outfalls and corresponding disposal ponds and monitor pH, iron (Fe), aluminum (Al), chromium (Cr)...
متن کاملRole of Natural Organic Solutes on the Sorption of Selenium by Coal Mine Backfill- Core Samples from the Powder River Basin, Wyoming
Concentrations of dissolved selenium (Se) as large as 330 pg L-' have been detected in water samples &om bacW aquifers in the southern Powder River Basin (PRB) of northeastern Wyoming. During d a c e coal mining, rock mstwial overiymg the coal is redistributed in relation to its original stratigraphic position; exposure of the prewiously buried material to surface oxidizing conditions decreases...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Impact of Mine Waters on River Water Quality in the Upper Silesian Coal Basin
The Upper Silesian Coal Basin (USCB) is located within the Vistnla and Oder basins in the southern part of Poland. The coal seams in the USCB are exploited by the underground mining of average depth of 650 m, up to 1200 m. Studies on hydrogeochemical environment showed a normal vertical and horizontal hydrogeochemical zonation in the whole of USCB. As a general trend the level of groundwater mi...
متن کاملThe geochemical evolution of water coproduced with coalbed natural gas in the Powder River Basin, Wyoming
Water produced with coalbed natural gas (CBNG) attains its characteristic sodium-bicarbonate composition through a series of processes, including dissolution of salts, precipitation of salts, pyrite oxidation, ion exchange, sulfate reduction, and methanogenesis. After CBNG-produced water is discharged to the surface, interaction with the atmosphere will initiate the precipitation of calcite, ir...
