摘要
在常压、高压搅拌釜中,测定了CO_2在N-甲基二乙醇胺(MDEA)水溶液中的溶解度.实验温度40～100°C,CO_2分压1～1000kPa,MDEA浓度2.0～4.28kmol/m^3.用测得的平衡数据,分别建立了能满足工程应用的简化模型和热力学模型.本立用Gibbs-Duhem方程计算了CO_2在MDEA水溶液中的溶解热.
The solubility of CO2 in aqueous methyldiethanolamine solutions was measured in atmospheric pressure cell and high pressure cell, respectively. The experimental temperature was from 40 to 100℃ , CO2 partial pressure was from 1 to 1000 kPa and the concentration of methyldiethanolamine was from 2. 0 to 4. 28 kmol/m3. A simple model and a thermodynamic model which can be used for engineering calculation were established by using the solubility data determined. The heat of solution were calculated from the experimental results with the Gibbs -Duhem equation.
