Synthesis Of Carbide Ceramics Via Reduction And Carburization Of Oxyanions Adsorbed Onto An Activated Carbon Matrix, Grant Wallace

Graduate Theses & Non-Theses

Carbide ceramics rank high among the hardest and most chemically resistant materials. Their ability to resist physical and chemical attack under conditions where more traditional materials fail make them very desirable for a number of industrial applications. Their use is limited, however, due to the expensive and energy-intensive methods required to produce them commercially.

A more versatile and energy-efficient process for commercial carbide production has been developed by synthesizing micron/sub-micron carbide ceramic particles through the adsorption and subsequent carburization of anions on an activated carbon matrix. Oxyanion solutions containing sodium tungstate, sodium molybdate, or sodium metasilicate are adsorbed onto activated …

Modeling Unconventional Water Production In The Northeast Elm Coulee Field, Bakken Formation, Jan Branning

Graduate Theses & Non-Theses

Wells within the Northeast (NE) Elm Coulee produce significantly higher water cuts than wells within Elm Coulee Proper. The purpose of this work was to identify the source of produced water in the NE Elm Coulee. An area within the NE Elm Coulee was selected for a numerical flow simulation analysis, and a total of three models of the project area were constructed by isolating production mechanisms to determine the source of produced water in the NE Elm Coulee. A Separate Tank model was constructed to determine if the source of the produced water was matrix water saturation in the …
