The Effect of Porous Media Properties on Effective Thermal Conductivity of Tetrahydrofuran Hydrate and Evaluation of Existing Prediction Correlations
Sinopsis
Thermal properties of porous media containing gas hydrates govern the heat transfer process during dissociation
of gas hydrates and directly impact the gas production rate and energy efficiency. The effective thermal conductivity of hydrate-bearing porous media reflect the capacity to transfer heat and energy. The primary
objective of this paper is to investigate the effect of porous media properties on the effective thermal
conductivity of tetrahydrofuran hydrates and estimate the typical prediction models. Thus, the effective thermal
conductivity of samples with different porosity, hydrates saturation and porous materials is measured. The
agreement of experimental data with the results calculated from different models is evaluated, and the relatively
accurate model is figured out. Furthermore, we provide a fitting model that is suitable for our experimental
conditions. Additionally, X-ray CT apparatus is employed in this study to determine the porosity and hydrates
saturation of the sample using the calculation method. The extension of the studies to natural gas hydrates could
have implications in understanding the control mechanism of gas hydrates dissociation and the heat transfer
process in the internal reservoir during gas production.
