Measurements for the density and viscosity of partially carbonated solutions containing water, piperazine (PZ), and a tertiary amine, which was either dimethylaminoethanol (DMAE) or 2-diethylaminoethanol (DEAE), were conducted with total amine mass fractions of 30% and 40% over a temperature range from 298.15 to 353.15 K. Density and viscosity correlations of these mixtures were developed as functions of amine mass fraction, CO₂ loading, and temperature. For both systems investigated, the average absolute relative deviations of the experimental data from these correlation are approximately 0.2% for density and 3% for viscosity. The correlations will be useful for thermodynamic analysis and computer simulations of carbon capture processes utilizing these promising blended amine systems.

含叔烷醇胺和哌嗪的部分碳酸化水溶液的密度和粘度，温度为298.15至353.15 K

含有水，哌嗪（PZ）和叔胺（即二甲基氨基乙醇（DMAE）或2-二乙基氨基乙醇（DEAE）的叔胺）的部分碳酸溶液的密度和粘度的测量是按总胺质量分数分别为30％和40进行的。在298.15至353.15 K的温度范围内，这些混合物的密度和粘度相关性是胺质量分数，CO ₂负载量和温度的函数。对于所研究的两个系统，实验数据与这些相关性的平均绝对相对偏差（对于密度）约为0.2％，对于粘度约为3％。这些相关性对于利用这些有前途的混合胺系统进行碳捕获过程的热力学分析和计算机模拟非常有用。
