悬垂水滴与悬浮气泡表面气体水合物形成特性对比

摘要

Based on a set of high-pressure visual experiment device used for the natural gas hydrates crystallization and growth on the surface of suspended water droplet and suspended bubble,the influence of factors such as pressure,temperature,water quality on the crystallization and growth are analyzed and discussed respectively.Comparative analysis of the experimental phenomena about the characteristics of hydrate formation on the surface of suspended water droplet and bubble was discussed.Temperature and pressure are the important factors of hydrate crystallization and growth.The decrease of temperature or the increase of pressure will also improve the growth of hydrate.This paper also provides experimental support for the development of spray and bubbling method to improve the hydrate formation.%基于悬垂水滴和悬浮气泡表面形成气体水合物的可视化耐高压实验装置，分析探讨了反应压力、温度、水质等因素对水滴和气泡表面气体水合物成核和生长规律的影响。对已有的关于研究单个静止悬垂水滴和悬浮气泡表面气体水合物生长特性的实验现象及结果进行了对比分析，得出结论：温度和压力是影响表面水合物结晶与生长的重要因素；温度的降低或压力的升高均使水合反应速度加快。研究为发展喷雾法和鼓泡法这两种强化制备水合物的方式提供了有效的实验支撑。
