This study investigates the effects of types of impellers and baffles on methane hydrate formation. Induction time, water conversion to hydrates (hydrate yield), hydrate formation rate and hydrate productivity are components that were estimated. The initial hydrate formation rate is generally higher with the use of Ruston turbine (RT) with higher values 28.93 × 10 −8 mol/s in RT/RT with full baffle (FB) experiment, but the decline rate of hydrate formation was also high compared to up-pumping pitched blade turbine (PBTU). Power consumption is higher also in RT/RT and PBT/RT with higher value 392,000 W in PBT/RT with no baffle (NB) experiment compared to PBT/PBT and RT/PBT experiments respectively. Induction time values are higher in RT/RT experiments compared to PBT/PBT ones. Hydrate yield is always smaller when there is no baffle in all four groups of experiments while the higher values exist in experiments with full baffle. It should be noticed that PBT is the same with PBTU, since all experiments with mixed flow have upward trending.

双叶轮对甲烷水合物形成的动力学分析

这项研究调查了叶轮和挡板类型对甲烷水合物形成的影响。诱导时间，水到水合物的转化率（水合物产率），水合物形成速率和水合物生产率是估计的成分。在采用全挡板（FB）实验的RT / RT中，使用具有更高值28.93×10 -8 mol / s的Ruston涡轮（RT），初始水合物形成速率通常较高，但是水合物形成的下降速率也很高与向上泵送​​的变桨叶片涡轮（PBTU）相比。RT / RT和PBT / RT的功耗也较高，无挡板（NB）实验的PBT / RT的值分别为392,000 W，分别高于PBT / PBT和RT / PBT的实验值。与PBT / PBT相比，RT / RT实验中的诱导时间值更高。在所有四组实验中都没有挡板的情况下，水合物产量始终较小，而在全挡板实验中存在较高的水合物产量。应当注意，PBTU与PBTU相同，因为所有混合流实验均呈上升趋势。
