项目摘要
Quantitative description of the primary nucleation kinetic region is vital to the state-of-the-art in hydrate research. Without kinetic research, the basic physics and chemistry cannot be used to interpret the fundamentals of hydrate formation. Since the kinetics of primary nucleation from liquid water seems experimentally elusive and resists duplication in different laboratories, the starting point must be experiments which are reproducible - those kinetic data obtained for hydrate formation from ice. This first step has useful analog for later extension to hydrate formation from liquid water. The impact of the proposed research represents a part of a turning point in the history of hydrate research from time- independent studies (thermodynamics) to time-dependent (kinetic with physical forces) studies. The results of the work are too long-range to be supported by industry. Yet the results have impact on such diverse problems as rates of gas release from hydrates for environmental problems, energy recovery, and the plugging of pipelines in the North Sea environment.
一次成核动力学区域的定量描述对水合物研究的最新水平至关重要。没有动力学研究,基础物理和化学就不能用来解释水合物形成的基本原理。由于液态水的初级成核动力学在实验上似乎难以捉摸,而且不能在不同的实验室重复,因此必须从可重复的实验开始--那些从冰中形成水合物的动力学数据。这第一步对以后从液态水形成水合物的推广具有有用的类比。拟议研究的影响代表了水合物研究历史上一个转折点的一部分,从与时间无关的研究(热力学)转向依赖时间的(考虑物理力的动力学)研究。这项工作的结果太过长远,无法得到业界的支持。然而,这些结果对各种问题都有影响,比如由于环境问题而从水合物中释放天然气的速度,能源回收,以及北海环境中的管道堵塞。
