The performance of a packed bubble column operated in countercurrent and cocurrent manner was investigated and compared with that of an unpacked bubble column. The column was a 10 cm i.d. acrylic tube packed with Raschig rings of 0.8, 1.27 and 2.54 cm. The gas hold-up, the pressure drop, the apparent dispersion coefficients, the liquid-phase capacity coefficients of mass transfer and the gas-liquid interfacial area were measured. As the effects of the use of packings, it was found that the values of the capacity coefficient for the packed bubble column become similar to those for the bubble column because of the reduction of liquid mixing, and that an increase of gas hold-up results in an increase of the interfacial areas.
