Methane hydrate film growth kinetics
Web6 sep. 2024 · This confirms the validity of using equation (3) to describe the kinetics of gas hydrate film growth along the water–gas interface. From the comparison of the calculated data obtained by equation (3) with the experimental data presented in Fig. 3, it was determined that the coefficient n has a value from 0.70 to 0.72. Web18 jul. 2002 · The rates of sI methane hydrate formation were measured in-situ under isothermal conditions with a methane pressure of 1000 psi (6.9 MPa). Kinetic data were analyzed in terms of a shrinking core model, including possible contributions of nucleation, methane diffusion, and interface reaction.
