Applicability Research of Thermodynamic Models of Gas Hydrate Phase Equilibrium Base on Different Equations of State
This study is based on statistical thermodynamics, considering the changes in water activity caused by gas dissolution, and deriving and summarizing four thermodynamic models. Based on the collected 150 experimental data points, the accuracy of the four thermodynamic models in predicting the phase e...
