Absorption Performance

Based on CO2-NaOH system, the absorption performances and the mass transfer of the rotating packed bed with the three different types of the gas-liquid distribution inducer were investigated. The experimental results showed that the structure of the gas-liquid distribution inducer have an important effect on the volumetric mass transfer coefficient and the absorptivity of CO2. Due to the enhancement of the countercurrent contact between the liquid phase and the gas phase from the installation of the distribution inducer, an increasement of the volumetric mass transfer coefficient and a higher absorptivity of CO2 could be obtained than those of the experiment in PRB without any inducers. Among the distribution inducers, the combination of the liquid distribution inducer of Type-B and the gas distribution inducer of Type-A could give a better volumetric mass transfer coefficient and a higher absorptivity of CO2, which were 27.84×10-3 s-1 and 80.00%, respectively.

Rotating Packed Bed

Based on acetone-H2O system, the influence of the gas-liquid distribution inducer on the mass transfer coefficient in the rotating packed bed with the stainless steel packing was investigated. Furthermore, the absorption performance was also obtained under the experimental condition of the rotational speed of 630 rpm, the gas flow rate of 2 m3/h and the liquid flow rate of 100 L/h in the rotating packed bed with different types and different installation ways of the distribution inducer. The experimental results showed that the volumetric mass transfer coefficient Kyα per unit contact length of gas-liquid was increased by 8.6% for the forward-curved fixed blade, by 19.8% for the backward-curved rotor blade and by 33.2% with the combination of the straight radial rotor blade and the backward-curved fixed blade, respectively. Furthermore, when the gas flow rate was 2.5 m3/h, Kyα per unit contact length of gas-liquid was increased by 2.9% for the forward-curved fixed blade, by 25.3% for the backward-curved rotor blade, by 42.7% for the combination of the straight radial rotor blade and the backward-curved fixed blade, respectively. The results indicated that the distribution inducer play an important role on the improvement of the mass transfer coefficient in acetone-H2O system.
