| 英文摘要 | experimental data on the kinetics of c2h6 hydrate formation in the presence of pure water and two aqueous single solutions, mgcl2 and nacl, are presented in this study. the measurements of experimental hydrate formation process were performed in a high pressure reactor at 276.15 k, at initial pressure range of 2.0-2.4 mpa, and solution concentration range of 2.34-10 wt%. the effect of solution concentration and initial pressure on the induction time, gas consumption, conversion, and storage capacity and growth rate was examined. it was observed that with the increase of the solution concentration, the induction time increased, while the storage capacity and the number of moles of c2h6 consumed decreased. a diffusion-reaction kinetics model was employed to predict the hydrate growth rate at the beginning of hydrate formation. the results showed that the addition of mgcl2 and nacl decreased the apparent rate constant, and mgcl2 had a greater effect than nacl in inhibiting the hydrate growth. |
