Abstract For the first time, numerous experiments were carried out to evaluate the effect of electric field (EF) on the mechanism of naturally occurring THF hydrate formation. The Statistical Package for the Social Sciences (SPSS) software was utilized to analyze the experimental data. First, the effect of static electric field (SEF) strength on nucleation temperature (T-nuc) and growth time (t-growth) studied. Based on the statistical results, increasing the intensity of SEF induces nucleation at a relatively high temperature. Furthermore, the completion of solidification takes a longer time than the same process in the absence of SEF. The notable point is that by switching a SEF to a pulsed electric field (PEF) of equal voltage, the EF effectiveness on the two mentioned kinetic parameters significantly reduces. The other point is that applying EF heightens the enthalpy of fusion of THF hydrate.

静态和脉冲电场下的水合物形成

摘要 首次开展了大量实验来评估电场 (EF) 对天然存在的 THF 水合物形成机制的影响。社会科学统计软件包(SPSS)软件用于分析实验数据。首先,研究了静电场 (SEF) 强度对成核温度 (T-nuc) 和生长时间 (t-growth) 的影响。根据统计结果,增加 SEF 的强度会在相对较高的温度下诱导成核。此外,与没有 SEF 的相同过程相比,凝固的完成需要更长的时间。值得注意的一点是,通过将 SEF 切换到相等电压的脉冲电场 (PEF),EF 对两个提到的动力学参数的有效性显着降低。
