摘要
以MEA为主体，DETA为添加剂，考察1h内，在温度298～338K，压力300～700kPa，混合胺溶液初始浓度（质量分数）4％～20％范围内，MEA＋DETA不同配比的混合吸收剂吸收CO2的特性。获得MEA＋DETA混合胺吸收CO2的最佳吸收条件为：308K、500kPa、总胺质量浓度为20％，MEA与DETA的配比为8：2。
The absorption characteristics of blended amine solutions of MEA ＋ DETA were studied under different conditions. The temperature ranged from 298 K to 398 K. The pressure ranged from 300 kPa to 700 kPa. The initial concentration of blended amine solution changed from 4% to 20%. The results show that the op- timal experimental conditions for CO2 absorption are temperature of 308 K, pressure of 500 kPa, the total amine concentration of 20% , and the mixing ratio between MEA and DETA of 8： 2.
