【摘要】 天然气水合物是一种类似冰的笼形晶体水合物。水合物形成热力学性质的研究是水合物形成抑制、能源利用、储存天然气、CO2 处理、海水淡化等的基础。文章介绍了一套新的可视化高压流体测试系统 ,讨论了气体水合物相平衡测定的几种方法 ,分析了图形法和观察法的优缺点。利用可视化高压流体测试系统运用图形法和观察法对甲烷体系的水合物相平衡进行了实验比较研究更多还原

【Abstract】 Gas hydrates are crystalline compounds,like ice.The thermodynamics of hydrate formation are important in the applications for suppression of hydrate formation,as an energy resource,for storage of natural gas,for storing CO 2,desalination of saltwater.This paper presents a new set of visual high-pressure fluid test system,discusses some methods to measure hydrate phase equilibrium and analyzes the advantage and disadvantage of graphical method and visual method.The gas hydrate phase equilibrium data of methane are measured by graphical method and visual method using the visual high-pressure fluid test system.更多还原
