Description

Effect of self-preservation of gas hydrates was explored over many years but there is no complete understanding how can hydrates exist in their thermodynamic instability region. We are suggesting the microscopic-level model of methane hydrate clusters immersed in ice matrix. Due to differences in thermal expansion of methane hydrate and Ice Ih the additional pressure appears in the hydrate phase and this moves it into its stability field. MD simulations were performed to find local pressure and density profiles. Results are well confirming our assumption
