| 摘 要： | 瓦斯水合物相平衡热力学条件的确立及改善是瓦斯水合化方法实现工业化的关键。利用可视化水合物相平衡实验装置,结合相平衡温度搜索法与观察法测定0.25 mol/L SDS溶液体系中四种不同瓦斯水合物相平衡条件,探究丙烷对瓦斯水合物热力学相平衡条件的变化规律,结果表明:丙烷的加入将水合物结构类型从Ⅰ型转为Ⅱ型,使得4.0~7.0 MPa范围内含丙烷瓦斯水合物生成相平衡温度升高,温差最大至13.7℃,大幅度改善了瓦斯混合气水合物热力学条件;丙烷含量越高,水合物相平衡条件改善效果越好。

| Abstract: | An effective improvement in the thermodynamic conditions of phase equilibrium for the gas hydrate holds the key for the industrial application of hydrate-based technology.This paper introduces the efforts aimed at obtaining phase equilibrium conditions for four kinds of different gas mixtures using the visual hydrate phase equilibrium equipment,combined with the temperature search method and the direct observation method,and analyzes the effect of propane on phase equilibrium of gas hydrate.The results show that the addition of propane permits the hydrate structure to be changed from type Ⅰ to type Ⅱ; with the pressure experiment condition of 4.0 ～ 7.0 MPa,the gas hydrate phase equilibrium temperature is allowed to rise by as much as 13.7 ℃ ; and an increase in propane content produces a better improvement in the phase equilibrium condition. |
