Performance of MDEA-PZ-TETA for Absorption and Desorption of CO₂

Abstract:

The absorption performance of CO₂ from the simulated flue gas using fresh MDEA-PZ-TETA absorbent and the desorption behavior of CO₂ from the CO₂-saturated absorbent were investigated. In the process of CO₂ absorption, the absorption temperature and the inlet flow rate of CO₂ played important effects on the absorption performance. The experimental results showed that the suitable absorption condition of CO₂ using fresh absorbent was the absorption temperature of 20 oC for 18 min and the inlet flow rate of CO₂ of 50 mL/min. In the process of CO₂ desorption from the used absorbent, the desorption temperature played an important role and the regeneration time had little effect on the desorption behavior. The suitable desorption condition was the desorption temperature of 105 oC for 1.0 h and the regeneration time of 1.
