Through the experimental apparatus, three phase equilibrium conditions of gas-water-hydrate were measured and enthalpy change in the dissociation process was analyzed based on the equilibrium results. Using methanol as chemical additive, the phenomena of hydrate formation and inhibition were investigated according to varying concentrations of the additives. Consequently, the plugging phenomena of subsea pipeline and flowline in natural gas production can be predicted by examining the hydrate formation and inhibition conditions. Specifically, the results of this study can be applied to the selection of the prevention criteria and method of hydrate formation.
