一种纯气体水合物相平衡的判定方法

A Judgment Method of Pure Gas Hydrate Phase Equilibrium

分析了国内外气体水合物相平衡测定方法,在恒温压力搜索法的基础上,通过合理的改进,设计了一套可以应用于反应盲釜中气体水合物相平衡判定的实验方法。以甲烷水合物相平衡实验为例,介绍了该改进方法的原理、操作步骤及实验结果,实验结果与软件预测结果吻合较好,误差在工程应用的允许范围内。

The measurement methods of gas hydrate phase equilibrium at home and abroad are analyzed. An experimental method applicable for judgment of gas hydrate phase equilibrium in the autoclave is designed by suitably modifying the isothermal pressure search method. Taking methane hydrate phase equilibrium experiment for example, the principle of the modified method, the operation procedures and the experimental result are introduced. The experimental result agrees well with the software prediction result, and the error is within the allowable range of engineering application.
