摘　　要：开发了一种新型的复合胺吸收剂,考察了该复合胺吸收剂和一乙醇胺溶液对二氧化碳的吸收和解吸能力,并在原理试验流程上评价了2种溶液对低浓度二氧化碳的连续吸收性能。结果表明,该复合胺吸收剂对二氧化碳具有较高的吸收速率和吸收容量,容易再生;在相同工艺条件下,复合胺溶液对低浓度二氧化碳的连续清除效率与一乙醇胺溶液相近,但稳定性更好。This work presents an investigation of carbon dioxide（CO2） absorption/desorption performance of a novel mixed amine solvent（MAS）,as well as aqueous monoethanolamine（MEA）.Also,the absorption properties of these two solvents for low concentration of CO2 have been tested using a schematic CO2 removal apparatus.The results indicate that MAS has high absorption rate,high absorption capability and can be regenerated easily.Under the same conditions,the CO2 removal efficiency of MAS is similar to that of MEA solution while MAS has better stability.
