Formation and Economic Study on Hydrate Technology with NGH Pellets

This study presents economic and formation investigations on hydration effects by looking at natural gas hydrate (NGH) storage and transportation processes and formation conditions. The investigation includes experiments with methane. The obtained results show that the methane formation time increased linearly as the subcooling temperature decreased. Furthermore, the economic result indicates that the energy consumption parameter is appropriate for examining resource consumption for a system that, in turn, results in optimal capital investment through the storage and transportation process of NGH. The results also show that energy consumption increases logarithmically as the hydrate formation pressure increases. Finally, the study shows that the initial cost of the NGH transport chain is lower than the initial liquefied natural gas (LNG) transport cost.
