混合有机胺吸收烟道气中CO_2的实验研究

Study on absorption of CO_2 into aqueous blends of DETA/TETA and MDEA

以工业应用为背景 ,采用双搅拌釜反应器 ,对 DETA(二乙烯三胺 ) +MDEA( N-甲基二乙醇胺 )、TETA(三乙烯四胺 )+MDEA混和有机胺水溶液吸收模拟烟道气中 CO2 进行研究。结果显示 ,在 MDEA中加入少量烯胺 DETA、TETA,可显著提高CO2 吸收速率和吸收容量 ,增强传质效果。其吸收 CO2 的效果优于常用的 MEA(一乙醇胺 )和 DEA(二乙醇胺 )

The absorption of CO-2 in flues into aqueous blends of DETA/TETA and MDEA was conducted. This process was studied in a stirred-cell absorber. Experimental results showed that the absorption rate and capacity of CO-2 can be remarkably enhanced by the system of DETA/TETA and MDEA. And the effect is better than the absorption into MEA or DEA.
