摘要：

Natural gas hydrates from different types and concentrations of surfactant solutions were produced and dissociated in a high-pressure cell. The Clausius-Clapeyron equation was utilized to derive the enthalpy related to the phase transition of the gas component from dissociation data. The results indicated that the phase change enthalpy of the nonionic surfactant solution hydrate is higher compared to that of pure-water and anionic surfactant solution hydrates. Experimental results also show that surfactants do not influence the thermodynamic dissociation point.
