中文摘要：

CO2作为全球温室气体，正在危害人类赖以生存的环境，而工业上现正在大力发展有机胺溶液用于脱除烟气中的CO2，并已得到了广泛的应用和极好的发展趋势．由于三乙烯四胺（TETA）溶液具有稳定性好、吸收效率高等优势，再对比传统胺试剂试验的浓度，试验选取0．2～0．8mol／L体积浓度范围的TETA作为吸收剂吸收模拟烟气中的CO2．当温度在25-40℃时，其温度对C02吸收速率的影响不明显；当溶剂体积浓度在0．2～0．8mol／L和CO2体积分数在10％～18％时，溶剂体积浓度和CO2体积分数对C02吸收速率的影响明显．

英文摘要：

As the world＇s greenhouse gas, carbon dioxide （CO2） is endangering human survival environment. The organic amine solution is widely used in industry to remove CO2 from flue gas, which has a good development trend. Compared with the concentration of the traditional amine reagent test, the three ethylene four amine（TETA） in the range of 0.2 to 0.8 mol/L is chosen as the absorbent to absorb the simulated flue gas for the good performance. The experimental results show that the effect of temperature on the absorption rate of CO2 is not obvious as the temperature is between 25 ℃ and 40 ℃, while the absorption rate of CO2 was observably when the volume concentration of the solvent is between 0.2-0.8 mol/L and the volume concentration of CO2 is between 10% and 18%.
