| 摘 要： | 用全自动表面张力仪测定了293．15-323．15K温度范围内，具有不同C02载荷的乙醇胺（Monoethanolamine，MEA）水溶液的表面张力，提出了计算MEA-CO2-水体系表面张力的半经验模型，计算结果与实验值吻合良好．通过实验和计算相结合，阐明了温度、MEA浓度和C02载荷对MEA-CO2-水体系表面张力的影响规律．

| Abstract: | The surface tensions of carbonated monoethanolamine aqueous solutions from 293.15 to 323.15K were measured by using an automatic surface tension-meter. A semi-empirical model applicable for the surface tensions of MEA-COg-water mixtures was proposed and the calculated results agreed well with experiments. The influences of temperature, MEA concentration and CO2 loading were demonstrated on the basic of experiments and calculations. |
