本文叙述了甲基二乙醇胺-环丁砜-水脱硫溶液的气相色谱分析方法。评价了预处理前后GDX-202的柱效率。在2m柱上实现了甲基二乙醇胺、环丁砜、水等7个组分的分离。以热导为检测器,用校正因子面积归一法定量。实验表明,含量≥5%质量分数的组分,分析相对误差在3%以下,含量<5%的组分,相对误差不大于12%。 This paper describes the gas chromatography method of methyldiethanolamine-sulfolane-water desulfurization solution. The column efficiency of GDX-202 before and after pretreatment was evaluated. In the 2m column to achieve methyldiethanolamine, sulfolane, water and other seven components of the separation. Using thermal conductivity as a detector, the calibration factor area was normalized. Experiments show that the content of ≥ 5% mass fraction of the analysis of the relative error of less than 3%, content <5% of the components, the relative error of not more than 12%.
