| 摘 要： | 为使多组分瓦斯气体迅速固化、储运,利用可视化水合物实验设备,研究了三种多组分气样在0.1 mol/L四氢呋喃(THF)和0.2 mol/L十二烷基硫酸钠(SDS)复配溶液中的水合固化过程,实验获取了水合物生成过程的压力-温度-时间曲线,结合水合物生长速率模型对实验数据进行计算和分析。结果表明:三种气样中随着丙烷含量的提高,生长速率呈增大趋势,在一定程度上可以提高水合物生长速率,抑制水合物中甲烷的含量。 |
| 关 键 词： | 丙烷 水合物 生长速率 固化储运 |

| Abstract: | Aimed at curing,storing,and transporting the multi-component gas samples at a faster speed,this paper is focused on using visualization hydrate laboratory equipment to investigate the hydration curing processes of three kinds of multi-component gas samples,as occurs in complex solution consisting of 0.1 mol /L tetrahydrofuran(THF) and 0.2 mol /L sodium dodecyl sulfate(SDS).The paper describes the pressure-temperature-time curve(p-t) in the formation process and the analysis and calculation of the gas hydrate formation rate,combined with the formula of gas hydrate.The results show that the increased propane concentration in three gas samples is followed by an increasing tendency in gas hydrate,thus contributing to improving the hydrate formation rate and inhibiting the methane content of hydrate,to a certain extent. |
| Keywords: | propane hydrate formation rate gas storage curing and transportation |
