Hydrogen Flooding of a Coal Core: Effect on Coal Swelling
نویسندگان
چکیده
Hydrogen is a clean fuel which has the potential to drastically decarbonize energy supply chain. However, hydrogen storage currently key challenge; one solution this problem geo-storage, with very large quantities of H2 can be stored economically. Possible target formations are deep coal seams, and permeability parameter determines how fast injected withdrawn again. it well known that gas injection into lead swelling, reduces permeability. We thus core measured dynamic permeability, while imaging via x-ray micro-tomography at reservoir conditions. Importantly, no changes in cleat morphology or were observed. conclude geo-storage seams feasible from fundamental petro-physical perspective; work aids large-scale implementation economy.

Estimation of coal swelling index based on chemical properties of coal using artificial neural networks
Free swelling index (FSI) is an important parameter for cokeability and combustion of coals. In this research, the effects of chemical properties of coals on the coal free swelling index were studied by artificial neural network methods. The artificial neural networks (ANNs) method was used for 200 datasets to estimate the free swelling index value. In this investigation, ten input parameters ...

متن کاملSwelling Measurements of a Low Rank Coal in Supercritical CO2
Coal swelling in the presence of water as well as CO2 is a well-known phenomenon, and these may affect the permeability of coal. Quantifying swelling effects is becoming an important issue to verify the suitability of particular coal seams for CO2-enhanced coal bed methane recovery projects. In this report, coal swelling experiments using a visualization method in the CO2 supercritical conditio...

Investigating the effect of fractures on unusual gas emission in coal mines; case study of Parvadeh coal mine, Iran
In the present study, an investigation was carried out on Parvadeh coal mine in Tabas, Iran, to survey the effect of fractures on unusual methane gas emission in coal mines. This coal mine was chosen for investigating because of its high methane gas content in the coal body and available data from sensors in desired locations. Gas concentration monitoring programs were carried out at the mine s...
