Assessing the Thermodynamic Feasibility of the Conversion of Methane Hydrate into Carbon Dioxide Hydrate in Porous Media
Concerns about the potential effects of rising carbon dioxide levels in the atmosphere have stimulated interest in a number of carbon dioxide sequestration studies. One suggestion is the sequestration of carbon dioxide as clathrate hydrates by injection of carbon dioxide into methane hydrate. Energy-supply research estimates indicate that natural gas hydrates in arctic and sub-seafloor formatio...
متن کاملCO2 EOR and Storage in Oil Reservoirs
CO2 EOR and Storage in Oil Reservoirs — CO2 injection into tertiary oil reservoirs has been widely accepted as an effective technique for enhanced oil recovery (EOR), and has been used by the oil industry for over 40 years. Concerns over greenhouse gas emissions are leading to the investigation and realisation of its potential as a carbon storage method in recent years. With the right reservoir...
متن کاملNon-equilibrium Molecular Dynamics Simulation of Dense Fluid Methane
We present a non-equilibrium molecular dynamics simulation of 125 methane molecules using a variant of the isokinetic “sllod” algorithm. The shear viscosity, pressure and internal energy of methane in a dense, supercritical fluid state (temperature 285.7 K and mass density 0.288 g/cm3) are calculated and the viscosity compared with experiment, with excellent agreement: the predicted shear visco...
متن کاملDynamic versus thermodynamic approach to non-canonical equilibrium
We study the dynamic and thermodynamic origin of non-canonical equilibria, and we discuss their connection with the generalized central limit theorem and the micro-canonical Boltzmann principle. We reach the conclusion that the zeroth law of thermodynamics and the Boltzmann principle are fulfilled thanks to an apparent fault turned into a benefit: the dynamic approach can only produce a truncat...
متن کاملThermal conductivity of methane hydrate from experiment and molecular simulation.
A single-sided transient plane source technique has been used to determine the thermal conductivity and thermal diffusivity of a compacted methane hydrate sample over the temperature range of 261.5-277.4 K and at gas-phase pressures ranging from 3.8 to 14.2 MPa. The average thermal conductivity, 0.68 +/- 0.01 W/(m K), and thermal diffusivity, 2.04 x 10(-7) +/- 0.04 x 10(-7) m2/s, values are, re...
