化学法吸收燃煤烟气中CO_2的研究

Study on CO_2 Absorption from Coal-fired Flue Gas by Chemical Method

以乙醇胺(MEA)和四乙烯五胺(TEPA)作为吸收剂吸收燃煤烟气中的CO2。在反应温度20℃、溶剂体积浓度5%、CO2体积浓度13%、模拟烟气流量550L/h时,MEA和TEPA的吸收速率分别为0.659和0.513mmol/s。

CO2was absorbed from coal-fired flue gas by chemical method with ethanolamine（MEA）and tetraethylenepentamine（TEPA）as solvents.The results show that absorption rate of MEA and TEPA is0.659 and 0.543 mmol/s respectively under the conditions including reaction temperature of 20 ℃,solvent volume concentration of 5%,CO2 volume concentration of 13%,and simulated flue gas flow rate of 550L/h.
