CO₂ Capturing by MDEA-PZ-TETA in a Rotating Packed Bed

Abstract:

The absorption performance of CO₂ using MDEA-PZ-TETA ternary absorbent in a rotating packed bed was investigated. The effects of the concentration of the ternary absorbent, the absorbing liquid temperature, the rotating speed, the liquid flow rate and gas flow rate on the absorption performance of CO₂ were discussed in detail. The experimental results showed that the optimum absorption condition was the absorbent concentration of 0.05 mol/L, the absorption temperature of 290 K, the rotating speed of 454 rpm and the ratio of gas to liquid of 1.2, which could provide a molar absorption saturated capacity of 1.3688 molCO₂/molAm and a satisfying CO₂ absorptivity of 93.18%.
