In this study, a power correlation for prediction of the mass transfer coefficient has been suggested for each regions of Forced-Circulation-Internal-Airlift-Loop Reactor (FCIALR). Based onexperimental data, the parameters of power correlation versus superficial gas velocity were determined for five regions, with high degree of confidence. The mass transfer coefficientincreases with increasing the superficial gas velocity in all regions of the reactor. The feed affectedregion has the greatest mass transfer coefficient and, contributing more than other region of FCIALR
