建立了一种半经验模型，用于估算吸收co2前后烷醇胺水溶液的热容，并利用回归技术获得了几种体系的模型参数。此外，还分析了纯单乙醇胺（MEA）、二乙醇胺（DEA）、n -甲基二乙醇胺（MDEA）、2-氨基-2-甲基-1-丙醇（AMP）和哌嗪（PZ）的热容数据，以及公开文献中报道的烷醇胺水溶液的热容数据。由于在回归过程中没有对同一系统的几个不同作者报告的数据进行加权，因此在评估不同作者报告的同一系统的实验数据的相对准确性时，使用了针对模型拟合中使用的实验数据集的模型预测的关键统计量。总的来说，模型预测与大多数已报道的实验数据非常吻合。
A semiempirical model for estimating the heat capacity of aqueous solutions of alkanolamines, both before and after CO2absorption, has been developed, and the model parameters for several systems have been obtained using regression techniques. Furthermore, the heat capacity data for pure monoethanolamine (MEA), diethanolamine (DEA),N-methyldiethanolamine (MDEA), 2-amino-2-methyl-1-propanol (AMP), and piperazine (PZ), as well as the heat capacity data for aqueous solutions of the alkanolamines that have been reported in the open literature, have been analyzed. Given that the data reported by the several different authors for the same system were not weighted during the regression, key statistics of the model predictions against the experimental data set used in the model fitting have been used in the assessment of the relative accuracy of the experimental data reported by different authors for the same system. Overall, the model predictions are in excellent agreement with most of the experimental data that have been reported.
