In this work, the induction time of hydrate formation of multicomponent gas mixtures on a water droplet has been modeled. Mass transfer through the droplet surface was modeled based on a diffusion equation where the rate of reaction was expressed based on the nucleation theory. Driving force for the hydrate formation was calculated based on the change in the Gibbs free energies of the gas, water and the hydrate. The model was validated by comparison of the predicted results with the experimental data from the literature. The induction time was calculated for hydrate formation from a mixture of 89.4% methane + 10.6% ethane on 1.5-7 mm in diameter of water droplets at 273.85 K and 3.6-5.1 MPa. It was found that, induction time is highly sensitive to the value of the driving force. Moreover, the induction times were not dependent on the size of the droplets and the induction time for the water droplets with hydrate memory was shorter than the droplets without hydrate memory. 5 63 Oil and Gas Science and Technology ARTICULO Sarshar, M. 40192 Esmaeilzadeh, F. 40193 Fathikaljahi, J. 40194 168902 168902 http://ogst.ifp.fr/index.php?option=article&access=standard&Itemid=129&url=/articles/ogst/pdf/2008/05/ogst07093.pdf 0 0 0 0 236721 BVIAPG BVIAPG 2026-03-05 200043690 0 200043690 2026-03-05 15:11:08 2026-03-05 ARTICULO
