Tomographic imaging of gas holdup distribution in pressurized bubble columns

The averaged and radial gas holdup as well as gas phase dynamics and approximate bubble size distribution were studied in a high-pressure bubble column reactor of 4000 mm height and 330 mm diameter. Novel imaging measurement techniques, namely high-resolution gamma-ray computed tomography and wire-mesh sensor, were developed and adapted to the industrial reactor system. The gas phase was nitrogen. Deionized water and cumene were applied as liquid phases. The effect of the superficial gas velocity was studied over a range of 0 to 0.05 m/s at low liquid superficial velocities of 0.008 and 0.018 m/s for operating temperatures and pressures up to 75°C and 18.5 bar, respectively.
