| Summary: | Gas hydrates are ice-like crystalline solids in which water molecules trap gas molecules in clathrate structures. They can preserve in low temperatures and elevated pressures and may exist in permafrost or deep marine environments. Natural gas hydrates are especially sensitive to the changes in temperature and pressure due to environmental changes. This can result in hydrate decomposition, which in turn may release enormous amounts of CH4 as the main component of natural gas hydrates. This study was an effort to use the molecular simulations for the estimation of possible gas release from the destabilization of natural gas hydrate reservoirs in response to environmental changes. The dissociation data for simple CH4 hydrates, CH4-C3H8 hydrates and CH4-C2H6-C3H8-CO2 mixed hydrates were provided by using molecular dynamics (MD) simulations. The MD simulations could provide a better understanding of the phenomena involved in the dissociation process of gas hydrates and help to explain the experimental ... |
