The kinetics of methane gas hydrate formation was obtained by different dual and dual mixed impeller experiments with surface baffle at 42.5 bars pressure and 2 °C temperature. The outcomes indicated that induction time is lower in radial flow experiments compared to mixed flow experiments due to better gas liquid contact, uniform shear stress and good pumping capacity compared to mixed flow ones with values less 15 min. Radial flow experiments showed higher values in hydrate yield although the duration of hydrate formation in radial flow experiments is less compared to mixed flow ones confirming the above outcomes with values more than 5%. Radial flow impellers indicated higher values in rate of hydrate formation compared to mixed flow impellers.

使用表面挡板的甲烷水合物形成动力学研究

甲烷气体水合物形成的动力学是通过在 42.5 巴压力和 2°C 温度下使用表面挡板进行不同的双和双混合叶轮实验获得的。结果表明,与混合流实验相比,径向流实验中的诱导时间较短,因为与值小于 15 分钟的混合流实验相比,由于更好的气液接触、均匀的剪切应力和良好的泵送能力。径向流实验显示出更高的水合物产率值,尽管径向流实验中水合物形成的持续时间比混合流实验要短,证实了上述结果的值超过 5%。与混流叶轮相比,径向流叶轮显示出更高的水合物形成速率值。
