《化学科学与工程前沿（英文）》 2016年 第10卷 第1期   页码 162-175 doi: 10.1007/s11705-016-1555-5

摘要： Aqueous solutions of methyldiethanolamine (MDEA) and piperazine (PZ) are commonly used solvent nowadays. In this work a thermodynamic analysis with the Electrolyte-NRTL model has been performed for systems composed of acidic gases and MDEA+PZ aqueous solution. ASPEN Plus has been used for thermodynamic modeling. Values of binary interaction parameters for liquid phase activity coefficients have been estimated from regressions of experimental data. Moreover, the influence of the interactions between ion pairs and MDEA or PZ molecular species has been analyzed. The final aim is to obtain a reliable tool for design and simulation of absorption and stripping columns, fundamentals also in order to carry out energy saving studies.
