Abstract
The fractional gas hold-up, effective interfacial area a and the liquid side mass transfer coefficient kLa were obtained from 100 and 200 mm i.d. packed bubble columns using wire gauze packings. The values of a and kLa were measured using chemical methods. Two modes of operation were studied: (i) semi-continuous and (ii) continuous counter-current. The gas and liquid velocities were varied in the ranges 20 - 300 mm/s and 1 - 5 mm/s, respectively. The values of a and kLa were found to be in the ranges 80 - 160 m2/m3 and 0.04 - 0.09 s−1, respectively. The performance of the wire gauze packings is compared with that of conventional packings.
