Thermal desorption systems are being utilized to remove toxic mercury compounds from coal. However, high moisture level, poor mixing, and unsuitable heating rate reduce the efficiency of thermal desorption units. Spouted bed reactor, which have been used in various physical operations such as drying, presents a possible solution in reducing moisture level and increasing particles mixing. The propo ...

The SCO2 Brayton cycle is gaining interest across a variety of power generation applications due to its potential for providing higher efficiencies. The range of industrial applications include: industrial waste and heat recovery, coal and nuclear power plants, and renewable energy sources such as solar thermal and fuel cells. Direct fired SCO2 cycle loops require combustors that operate beyond th ...

Drilling is equally important for survey purposes, for oil and natural gas exploration, and in searches for water in arid areas. Drill bits with extended service lives are needed to improve the economics of today’s drilling systems, particularly in high temperature, high pressure and erosive gases environments encountered in deep wells close to sources of hot magma. We will develop diamond-hard ...

Over the past decade, the growth of unconventional oil and gas has resulted in discovery and availability of vast quantities of natural gas across the United States. In many regions, lack or deficit of adequate infrastructure results in gas being stranded, or, in case of oil-associated gas, wastefully vented or flared, needlessly contributing to GHG emissions and global warming. Although manufactu ...

Data-intensive scientific applications incline to high performance computing which is getting more and more widespread in supercomputing centers, research laboratories, and universities. DoE and many organizations need an automatic and adaptive network analysis tool for effective anomaly detection and localization in the high speed network. Currently approaches, Pythia, APD, etc., are unable to pr ...

As legislation continues to tighten regulations on emissions for coal-fired power plants, new technologies and control strategies are required. Mercury and other coal contaminants are of interest due to the cost associated with capture and disposal of toxic mercury species. More recently, the Fossil Energy program at DOE has identified spouted bed systems for thermal desorption of mercury as a via ...

Dependence on fossil fuels for energy has led to a far reaching secondary problem of increasing carbon dioxide concentrations. This rise in CO2, as well as the other so called “greenhouse gasses” has in turn led to global climate change, and increasing temperatures. There is a need to go beyond the basic capture and storage approaches to mitigating this CO2 rise. With the ever growing demand f ...

Bioethanol has come into widespread use as fuel additives worldwide, especially in the U.S. and Brazil, aiming to mitigate CO2 emissions by up to 70% and sustain the carbon-neutral ecosystem. Generally, bioethanol in various fermentation broths has a maximum concentration of 6-8 wt.%. Hence, concentration of bioethanol from dilute streams poses a grand challenge from the standpoint o ...

Polarized 3He has been shown to be advantageous when used as an analyzer for polarized neutron scattering, an area of physics research that is growing quickly. The unique advantages of using polarized 3He as neutron spin filters, such as broadband and wide angular acceptance of neutron beams, have made it widely used in most neutron facilities. In order to polarize 3He gas, spin-exchange optical p ...

The Department of Energy and other federal agencies have made significant investments in high performance software engineering tools, yet these tools still lack advanced problem identification capabilities. At the moment, users must rely heavily on their own experience and intuition to interpret software performance data, identify the root cause of a software performance problem, and ultimately re ...
