摘　　要： 混合工质组分配比对混合工质循环气体液化系统的性能有较大影响,也是液化工艺和循环性能优化的重点。在实际系统的调试运行中,有必要对混合制冷剂组分进行定量分析。本文针对一种小型预冷式混合工质循环气体液化系统实验,建立了该系统工质组分的气相色谱分析方法,可快速、简便、准确地测定工质组分含量,为混合工质循环的实验优化提供了技术支持。 The composition of working fluids has con- siderable influence on the performance of the mixed refrigerant cycle (MRC) of gas liquefaction system and is also the key for optimization of the gas liquefaction process and cycle performance. During the adjustment and operation of actual system, it is necessary to analyze the working mixture composition quantitatively. In this paper, a composition testing method has been established, which is based on gas chromatography (GC) for the mixed refrigerant used in a small-scale pre-cooling cycle gas liquefaction system. It is shown that the developed method has the advantages of rapidity, simpleness, convenience and accuracy in determinating the composition of multi-component working fluids and can be effectively used to optimize the MRC gas liquefaction sys- tem.
