Experimental study on the effective thermal conductivity of methane hydrate-bearing sand 

Hydrate bearing sediments, found in permafrost, have great potential as a future energy source. Therefore, the thermal properties need to be determined to design drilling and gas extraction processes. The thermal conductivity was measured through a transient plane source (TPS) method. The thermal conductivity values show weak negative dependence on temperature. The effective thermal conductivity of hydrate-bearing sediment is strongly dependent on the water-saturation of the sand, the hydrates tend ...

Thermal conductivities of methane-methylcyclohexane and tetrabutylammonium bromide clathrate hydrate 

The thermal conductivities of gas hydrates are well documented, but the thermal conductivities of structure H (sH) methane-methylcyclohexane (MCH) hydrate and type A tetrabutylammonium bromide (TBAB) semi clathrate hydrate have no experimental data. The purpose of this study was to determine the thermal conductivities of sH MCH hydrate and TBAB semi clathrate hydrate. The thermal conductivity was measured using a single sided transient plane source (TPS) method. Most gas hydrates ...

Measurement and modeling of the effective thermal conductivity for porous methane hydrate samples

Gas hydrates have potential to be used as future energy sources, so it is important to understand their thermal properties. This paper aims to examine the effective thermal conductivity of synthetic porous methane hydrate samples. A Thermal Constants Analyser measured the thermal conductivity of the methane hydrate samples using the single-sided transient plane source (TPS) method. Results showed an inverse relationship between porosity and thermal conductivity. Unfortunately, mechanical pressure can ...
