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CO2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CO2载荷对MEA-CO2-水体系表面张力的影响规律.
The surface tension of aqueous solution of monoethanolamine (MEA) with different CO2 loadings at 293.15 ~ 323.15K was measured by using an automatic surface tension meter. A semi-empirical model for calculating the surface tension of MEA-CO2-water system was proposed. The calculated results Which is in good agreement with the experimental data.The effects of temperature, MEA concentration and CO2 loading on the surface tension of MEA-CO2-water system are illustrated through the combination of experiments and calculations.
