Abstract:

The characteristics of propane hydrate dissociation by methanol injection (mass fraction of 30.0％,60.1％,80.2％,99.5％) were investigated using a self-made visual equipment. The results indicate that the liquid temperature decreased slowly and the pressure in the reactors grew linearly when the dissociation reaction began, moreover, the dissociation time decrease with the methanol concentration’s increase,but the degree of decrease became weaker. The average dissociation rates are 0.020 59～0.045 35 mol/(min·L)，and increase linearly with the concentration of methanol solution. Compared with pure water injection, methanol injection reduces dissociation heat of gas hydrate and accelerates gas hydrate dissociation rate. The enhancement of concentration of methanol is benefit to promote dissociation of hydrate.

摘要： 在自制的可视化水合物开采装置中进行了以恒流量注入不同质量分数(30.0%，60.1%，80.2%，99.5% )甲醇溶液定容分解丙烷水合物的模拟化学试剂法分解天然气水合物实验。结果表明，分解实验开始后，釜内液相温度缓慢降低，压力近似于线性增长，分解时间随着质量分数的增加逐渐减少但减少的程度在减弱。通过计算得到丙烷水合物的平均分解速率介于0 .020 59～0 .045 35 mol/ (min·L)，并随注入甲醇质量分数的增加而增大。与注入纯水分解水合物实验相比甲醇的注入可以减少水合物分解时所需要的热量、加速水合物分解，同时提高甲醇的质量分数有利于加速水合物的分解。
