CO2在复合溶液MDEA-AMP中的溶解度

Solubility of carbon dioxide in mixed solution of MDEA-AMP

    摘要
  • 摘要:  测定了CO2在复合溶液N-甲基二乙醇胺（MDEA）＋2-氨基-2-甲基-1-丙醇（AMP）中的溶解度，研究了气相CO2浓度、温度和复合溶液的组分对溶解度的影响。实验获得了温度分别为25℃、30℃和40℃时，CO2在复合溶液MDEA-AMP中的溶解度。实验表明，溶解度随气相中CO2浓度升高或随AMP在复合溶液中的摩尔分数升高而升高，随温度升高而降低。

     

    Abstract: The solubility of CO2 in the mixed solution of methyldiethanolamine (MDEA) and 2-amino-2-methyl-1-propanol (AMP) was measured at 25℃, 30℃ and 40℃; the effects of CO2 concentration in gas phase, temperature and solution composition on the CO2 solubility were examined. The results indicted that the solubility of CO2 increases with the increase of gaseous CO2 concentration or the AMP content in the MDEA-AMP mixed solution, but decreases with the increase of temperature.
