Evolution of methane during gas hydrate dissociation

摘要: Abstract We simulated decomposition of structure I methane hydrate (H) with all cages filled in contact two reservoirs (pools) liquid water (W) which turn are either gas (G), or vacuum (V), under constant volume–constant energy conditions. By adding empty spaces to the simulation box we allow released diffuse out phase and into similar what happens during dissociation. The evolution molecules dissociation process was carefully monitored. found that some reaches contributes increase pressure on phase. As dissociates, becomes supersaturated methane, aggregate, spherical regions high concentration form identify as “nano-bubbles”. These nano-bubbles grew a specific size range depends conditions remained stable for duration simulations (5 ns).
