Sentence examples for high methane desorption from inspiring English sources

To achieve such goals, the drainage boreholes should be located in the zone with high methane desorption, high permeability, and high methane concentration.

The promotion mechanism of methane desorption on coals by the acoustic waves was also studied, it was found that the thermal effect of acoustic waves on methane desorption can be clearly seen.

Experiments of methane desorption on coals were performed under the effects of different acoustic frequencies and different acoustic intensities.

We would measure the volume of gas in the reservoir and it was very high methane 25-400% methane).

Since the existing desorption models cannot describe the desorption characteristics of methane on coals under the effect of the acoustic intensity, a correction term was introduced into the existing models in this study, and thus a new model that is able to describe methane desorption under the effect of acoustic waves was established.

However, the difference in methane desorption rate reduces when the coal particle size is more than 1.0 mm, indicating that a threshold of coal particle size exists in methane desorption in coal.

The results also show incorporating the desorption data from the time of exposure to 13 min of desorption tests is essential to typically reflect methane desorption kinetics in coal.

High methane yields of 449 462 LN kgVS were reached.

Optimal methane drainage relies on two key factors: constantly high gas flow and high methane concentration.

Without properly control of the methane desorption along with mining may cause severe disasters in deep coal mining, such as gas outburst.

It explains high methane concentrations in natural gas, methane enrichment over geologic time, and natural gas at thermodynamic equilibrium [3].
