摘要：
This paper presents a theoretically correct method for predicting the heat of dissociation of gas hydrates using a fugacity-based model. Based on the Clausius-Clapeyron equation, the proposed approach takes into account the difference in compressibility by phase transition and the solubility of a guest component in the liquid phase. It is found that, for specific gas hydrates, the effect of two correction factors on the prediction of the heat of dissociation is not negligible. All corresponding properties including the hydrate number, compressibility, solubility of gas in water, water content in the vapor phase, and heat of dissociation are calculated and compared with experimental values in part.
