天然气水合物生成与相平衡曲线的试验分析
|
摘要
通过改变动力学抑制剂、过冷度、搅拌,借助生成实验装置,分析天然气水合物的生成效果,比较以上三个条件下的天然气水合物的生成速度和生成量,进而得出以上三个变量的对天然气水合物生成效果的贡献。结果表明:增加搅拌在天然气水合物生成过程中起主要作用,其次是过冷度以及动力学抑制剂。通过对水合物生成以及分解过程中压力-温度曲线的拟合,放缓反应釜内温度的升幅,可以得到更长更精确的拟合曲线。
The effect of natural gas hydrate formation was analyzed with the experimental device by changing the kinetic inhibitors, undercooling and agitation.The generation rate and amount of natural gas hydrate under the above three conditions were compared. The contribution of the three variables to the formation of gas hydrate was finally obtained. The results showed that increasing agitation played a major role in the formation of gas hydrate, followed by supercooling and kinetic inhibitors. A longer and more accurate fitting curve could be obtained by fitting the pressure-temperature curve of hydrate formation and decomposition,and slowing the increase of temperature in the reactor.
