摘要
建立了一套可视化气体水合物测试系统 .利用该系统在 2 6 4 .76~ 2 88.96 K温度范围内测定了合成天然气在纯水和乙二醇水溶液中水合物的形成条件 .根据 Van der Waals Platteeuw的理想溶液等温吸附理论和 Moshfeghian Maddoc模型 ,给出了水合物相平衡计算模型 .水合物形成温度的计算结果与实验结果的平均相对偏差仅为 0 .2 2 % 。
A new visual experimental apparatus for measuring gas hydrate formation conditions is set up. It is used to measure hydrate equilibrium data of synthetic natural gas in aqueous solution of ethylene glycol in the temperature range of 264.76~288.96 K. A calculation model for gas hydrate equilibrium included inhibitor has been developed based on Van der WaalsPlatteeuw adsorption isotherm theory and MoshfeghianMaddoc. The average absolute difference temperature of hydrate formation conditions is only 0.22% between the calculating results and experimental results. This shows that the calculation model could well predict gas hydrate formation conditions in aqueous solution of ethylene glycol.
