Abstract
AbstractThe agitated‐pulsed column (APC) is expected to exhibit good transfer. The dispersed‐phase holdup and characteristic velocity were measured using a 25‐mm diameter APC. The holdup declined at first and then escalated with the increase of pulsation intensity which was in contrary to the trend of the characteristic velocity change. The pulsation intensity corresponding to minimum holdup was found, and it increased with higher agitation speed. The interfacial area was also calculated. Correlations were developed for the holdup and characteristic velocity prediction within 5.34 % and 9.54 % deviation, respectively. Flooding lines were calculated by the characteristic velocity method and operating regimes were determined by the experimental results.
