摘要

醇胺溶液在CO

捕集循环再生过程中易发生降解变质，导致有效胺浓度降低，进而影响CO

捕集性能。针对质量分数为26.71%的乙醇胺（MEA）变质胺液、总胺质量分数为20.63%的MEA-N-甲基二乙醇胺（MDEA）变质胺液（20.63%-D），采用减压蒸馏法对其进行了回收，并对回收胺液的CO

捕集性能进行了研究。结果表明，MEA变质胺液的胺回收率为94.42%，高于20.63%-D的胺回收率（75.49%）。总胺质量分数为40%的MEA-MDEA回收胺液（40%-R）的CO

解吸容量（1.71 mol/kg）为20.63%-D（0.86 mol/kg）的1.99倍，可基本满足燃煤电厂的CO

捕集需求。向40%-R中补加质量分数为5%的MEA可改善胺液的CO

捕集性能，所得胺液（40%-Ropt）的CO

吸收容量为1.95 mol/kg，比40%-R提高了0.14 mol/kg。

Abstract

Degradation often occurs during the cyclic regeneration of alkanolamine solutions for CO

capture

leading to reduction in effective amine concentration and consequently impairing CO

capture performance. Monoethanolamine (MEA) degraded amine solution with mass fraction of 26.71% and MEA-N-methyldiethanolamine (MDEA) degraded amine solution with total amine mass fraction of 20.63% (20.63%-D) were recovered via vacuum distillation. And CO

capture performances of the recovered amine solutions were evaluated. The results indicate that the amine recovery rate of MEA degraded amine solution is 94.42%

higher than that of 20.63%-D (75.49%). The CO

desorption capacity of MEA-MDEA recovered amine solution with total amine mass fraction of 40% (40%-R) (1.71 mol/kg) is 1.99 times that of 20.63%-D (0.86 mol/kg)

which can basically meet the CO

capture requirements of coal-fired power plants. Adding MEA with mass fraction of 5% to 40%-R can improve the CO

capture performance of the resulting amine solution (40%-Ropt). The CO

absorption capacity of 40%-Ropt is 1.95 mol/kg

which is 0.14 mol/kg higher than 40%-R.
