Absorption Performance of Rotating Packed Bed with Gas-Liquid Distribution Inducer

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.
