摘要
全球温室效应日益加剧,CO_(2)减排刻不容缓,乙醇胺(MEA)法作为目前工业上应用最广泛、技术最成熟的烟气CO_(2)吸收方法,具有吸收速率快、成本低的优点,但是其能耗大、吸收量小和易损耗的缺点也很明显。针对目前常见的MEA二元复合胺溶液展开对比分析,阐述了MEA二元复合胺溶液的研究进展,总结了MEA吸收溶液中加入其他醇胺溶液形成二元复合胺溶液后在吸收速率、吸收量和再生能耗等方面对CO_(2)吸收效果不同程度的改善情况。基于总结与分析,提出了吸收剂开发需要从吸收机理、溶解度、吸收负荷、解吸速率、解吸操作条件以及再生能耗等方面进行综合比选的思路,可为新型吸收剂的开发提供一定的指导。
The global greenhouse effect is increasingly intensifying, CO_(2)emission reduction is urgent. Ethanolamine(MEA) method as the most widely used in industry, the most mature technology of flue gas CO_(2)absorption method, has the advantages of fast absorption rate and low cost, but its disadvantages of large energy consumption, small absorption and easy loss are also obvious. Based on the comparison and analysis of the common MEA binary complex amine solutions, the research progress of MEA binary complex amine solutions was described. The improvement of CO_(2)capture effect of binary complex amine solutions formed after adding other alcoholamine solutions to the MEA absorption solution in terms of absorption rate, absorption amount and renewable energy consumption was summarized. It is proposed that the absorption mechanism, solubility, absorption load, desorption rate, desorption operating conditions and renewable energy consumption should be considered comprehensively in the development of absorbent, so as to provide certain guidance for the development of new absorbent.
