填料塔中AEE与MEA混胺对低浓度CO2的吸收OA北大核心CSCDCSTPCD
Absorption of low concentration carbon dioxide by mixed amines of AEE and MEA in packed tower
在常压下考察了体积分数20%乙醇胺(MEA)+2%N-甲基二乙醇胺(MDEA)与20%羟乙基乙二胺(AEE)+2%N-甲基二乙醇胺(MDEA)有机胺水溶液对CO2的吸收及解吸效果。考察了静态吸收和中试动态吸收实验。实验结果表明:在吸收温度及解吸温度相同的条件下,20%羟乙基乙二胺(AEE)+2%N-甲基二乙醇胺(MDEA)吸收剂对CO2的吸收及解吸效果要好于20%乙醇胺(MEA)+2%N-甲基二乙醇胺(MDEA),而且不易降解。达到同样的解吸效果…查看全部>>
Carbon dioxide absorption and desorption are investigated at ambient pressure in two aqueous amine solutions,20% monoethyamino(MEA) + 2% N-methyldiethanolamine(MDEA) and 20% 2-(aminoethylamino) ethanol(AEE) + 2% N-methyldiethanolamine(MDEA).Both solutions were studied using static and the dynamic methods.Results showed that the capacity of CO2 absorption and desorption in 20%AEE+2%MDEA is higher than that in 20%MEA+2%MDEA at the same absorption temperature w…查看全部>>
