At present, the traditional monoethanola mine (MEA) absorbent has a few drawbacks, including a low absorption rate, solvent degradation, and high energy consumption, which can restrict the development of absorption technology. Therefore, the application of hydroxyethyl ethylenediamine (AEE) has attracted increasing attention in recent years. In the past, the absorbent performance test was usually measured for a single use, where changes in the performance were rarely mentioned after several absorbent cycles. In the current work, the absorption and desorption performance of AEE absorbents at different concentrations for multiple cycles are investigated. The experimental results indicate that (1) 10 wt% AEE has a higher absorption rate; (2) 20 wt% AEE has a higher absorption, desorption rate, and degree of regeneration, but has higher energy consumption. (3) When the temperature reaches about 85℃, the desorption rate of three different concentrations reaches the highest level, and the desorption rate increases significantly with increases in the solution concentration. (4) After several cycles, the desorption rate and energy consumption of AEE solutions are always keep a great state, so the AEE solution can be used repeatedly. © Taiwan Association for Aerosol Research. |
