The effects of liquid depth, inclination angle of the column from vertically and baffle plates on gas holdup in bubble columns were determined, using three bubble columns.
When liquid depth Hl was less than the critical liquid depth Hlc, gas holdup εg decreased with increasing Hl, but when Hl was larger than Hlc, εg was nearly constant.
εg decreased with increasing column inclination angle, and the effect on εg was correlated.
εg was independent of the cross-sectional shape of the column.
Baffle plates set in bubble columns increased εg, and the effects of the area and number of baffle plates on εg were correlated.
