进行几种胺的CO2解吸分析以揭示胺再生过程的行为。选择了一种典型的伯胺（MEA）和另外两种仲胺（MMEA和DEA），在1-7 mol/L的不同浓度下制备胺溶液。生成并绘制再生曲线以描述该过程。发现将胺再生曲线区分为不同区域的特定CO2负载（mol/mol）对于特定胺是相同的，尽管浓度不同。这些点被定义为再生曲线上的“转折点”。MEA、MMEA和DEA的转折点分别位于0.40 mol/mol、0.38 mol/mol和0.28 mol/mol的CO2负载。根据慢区再生曲线的斜率，比较了三种胺的氨基甲酸酯稳定性。胺再生测试比较了在前2小时的相对热负荷：MMEA > MEA >> DEA，这与氨基甲酸酯稳定性的顺序相同。本文受版权保护。版权所有
The CO2 desorption analyses of several amines were performed to reveal the behaviour of the amine regeneration process. A typical primary amine (MEA) and two other secondary amines (MMEA and DEA) were selected, in preparation for amine solutions under different concentrations, from 1–7 mol/L. The regeneration curves were generated and plotted to describe the process. It was discovered that the specific CO2 loading (mol/mol) that distinguish the amine regeneration curves into different regions were the same for the specific amine, despite different concentrations. These points were defined as “turning points” on regeneration curves. The turning points of MEA, MMEA, and DEA are located at CO2 loadings of 0.40 mol/mol, 0.38 mol/mol, and 0.28 mol/mol, respectively. The carbamate stabilities of the three amines were compared with each other based on the slope of regeneration curves at slow region. The amine regeneration tests compared the relative heat duty at the first 2 h: MMEA > MEA >> DEA, which is the same order as carbamate stability. This article is protected by copyright.
