采用搅拌实验装置,研究AMP-MEA-DETA复合溶液对烟道气中二氧化碳的吸收和解吸性能,揭示了吸收速率、吸收容量与酸碱度、时间之间的内在联系,并对CO2初始逸出温度、试液再生温度、试液再生率进行了细致记录分析.结果表明,AMP-MEA-DETA三组分之间存在负相互作用;其吸收速率、吸收量大于AMP-MEA复合溶液、DETA单组份的吸收速率及吸收容量,小于两者之和;AMP-MEA-DETA三组分的再生温度为103℃左右,再生率为86.5％左右.%A set of stirring experimental was used to study the capability of absorption and desorption of carbon dioxide from flue gas with AMP-MEA-DETA complex solution. The study revealed the relationship between absorption rate, absorption capacity, pH and time. Meanwhile, the date was recorded and analys-ized, including the initial escape temperature of C02, regeneration temperature and regeneration rate in regeneration. Experimental results showed that the negative interaction existed among AMP,MEA and DE-TA, in which absorption rate and absorption capacity was higher than in AMP-MEA and DETA, but less than the sum of two. The regeneration temperature of AMP-MEA-DETA complex solution was about 103 t ,and the regeneration rate was about 86.5%.
