• Longitudinal liquid mixing in a concurrent multistage bubble column partitioned by perforated plates was observed by means of the thermal tracer technique. The mixing characteristic was expressed by combining the backflow through the plate and the dispersion in each stage. The backflow ratio of liquid through plate κ, which was defined by the ratio of backflow rate to the net flow rate of liquid, was independent of plate spacing and column diameter, and was affected by gas velocity uG, liquid velocity uL, free area of plate Ar, hole diameter of plate d0, plate thickness δ and liquid viscosity μ. The values of κ are empirically correlated with uG, UL, Ar, do, δ and μ. The dispersion coefficient in stage was smaller than that in the bubble column without partition plate.
