Biomethane potential (BMP) tests are a valuable tool to design different parts of full-scale anaerobic digestion plants. Recent inter-laboratory studies have shown that the results of BMP tests can vary considerably and a comparison of BMP test norm protoc ...
For understanding the behavior of a gas close to a channel wall it is important to model the gas-wall interactions as detailed as possible. When using molecular dynamics simulations these interactions can be modeled explicitly, but the computations are tim ...
This study aims at an investigation of the impurity gases emitted during the decomposition of borohydrides. For this we have set up a quantitative gas analysis based on a combination of FTIR spectroscopy and gravimetry. We show that the emission of various ...
Tropical reservoirs have been identified as important methane (CH4) sources to the atmosphere, primarily through turbine and downstream degassing. However, the importance of ebullition (gas bubbling) remains unclear. We hypothesized that ebullition is a di ...
Today’s world faces a large problem which is global warming. Glaciers melting see, and oceans water level rising, and droughts in Africa. According to [1] there are seven main sources of CO2 emissions from fossil fuels combustion: 1. Solid fuels (e.g. coal ...
Simulation of biodegradation of chlorinated solvents in dense non-aqueous phase liquid (DNAPL) source zones requires a model that accounts for the complexity of processes involved and that is consistent with available laboratory studies. This paper describ ...
The gas push−pull test (GPPT) is a single-well gas-tracer method to quantify in situ rates of CH4 oxidation in soils. To improve the design and interpretation of GPPT field experiments, gas component transport during GPPTs was examined in abiotic porous me ...
The growth of the porosity in high-burnup fuel is of particular interest when considering the effect of fission gas retention within the high-burnup structure (HBS). A mechanistic model of porosity growth under annealing conditions for light water reactor ...
We reinvestigate the Deterministic Lattice Gas introduced as a paradigmatic model of the 1/f spectra arising according to the self-organized criticality scenario. We demonstrate that the density fluctuations exhibit an unexpected dependence on systems size ...
In this paper, we propose a new methodology which is called multi stage production decision model that is suitable for companies with multi business line (gas distribution and Electricity generation) in the deregulated electricity market. We also consider ...
