A COMSOL Multiphysics®-based Model for Simulation of Methane-Hydrate Dissociation by Injection of Superheated Carbon Dioxide
Publié en 2013
Immense amounts of methane are stored as gas-hydrate deposits in deep layers of marine sediments. This has raised considerable interest to develop strategies for producing natural gas from marine hydrates. One potential production strategy is the injection of supercritical CO2 into methane hydrate-bearing sand layers to release the CH4 as a gas and sequester the CO2 as hydrate. We used COMSOL Multiphysics® to model the lab-scale experiments in which supercritical carbon dioxide was injected into a pressure vessel containing a mixture of methane-hydrate and quartz sand.
