Innovations in membranes for natural gas processing frequently consider ideal separation performance as the defining success metric for removing carbon dioxide (CO2) from methane (CH4). However, realistic natural gas feeds are complex mixtures…
Natural gas, as a very important source of energy and chemical feedstock, can be used in place of coal to lower net carbon dioxide emissions. Membrane separation technology is an attractive alternative for natural gas purification where the…
Leakage pathways through caprock lithologies for underground storage of CO2 and/or enhanced oil recovery (EOR) include intrusion into nano-pore mudstones, flow within fractures and faults, and larger-scale sedimentary heterogeneity (e.g., stacked…
Underground natural gas storage reservoir is generally used to stabilize the natural gas supply to meet the high and low peak of gas consumption. In addition, in the case of depleted gas reservoirs, the leftover native gas or cheap inert gas being as…
Improving predictive models for noble gas transport through natural materials at the field-scale is an essential component of improving US nuclear monitoring capabilities. Several field-scale experiments with a gas transport component have been…
Here we discuss the current state of knowledge on how atmospheric escape processes can fractionate noble gas isotopes and moderately volatile rock-forming elements that populate primordial atmospheres, magma ocean related environments, and…
Abstract.: Noble gases, and the way they fractionate, is a promising approach to better constrain origin, migration and initial state distributions of fluids in gas and oil reservoirs. Thermodiffusion, is one of the phenomena that may lead to isotope…
Gas-lift enhanced natural circulation of alkali and heavy liquid metals is a desirable option for passive cooling of advanced large, small, and micro nuclear reactors, accelerator driven systems, thermal solar plants, and experimental facilities and…
The terrestrial carbon to nitrogen ratio is a key geochemical parameter that can provide information on the nature of Earth's precursors, accretion/differentiation processes of our planet, as well as on the volatile budget of Earth. In principle,…
