Abstract

The incipient pressure of hydrate formation for methane and nitrogen was calculated in this work. The van der Waals and Platteeuw theory was used for modeling the hydrate phase while the vapor-liquid equilibrium was evaluated based on cubic equations of state, including the three parameters equations, and using Wong-Sandler mixing rules. Predictions of incipient pressure of hydrate formation were compared to experimental values and those results where conventional van der Waals mixing rules were applied. Our results showed no real advantage among the two mixing rules. Harmens-Knapp-WS y Harmens-Knapp-vdW equations of state produced less errors to predict the incipient pressure of hydrate formation for methane and nitrogen respectively.
