Abstract: Gas holdups of large bubbles and small bubbles were measured by means of dynamic gas disengagement approach in the pressured bubble column with a diameter of 0.3 m and a height of 6.6 m.The effects of superficial gas velocity, liquid surface tension, liquid viscosity andsystem pressure on gas holdups of small bubbles and large bubbles were investigated.The holdup of large bubbles increases and the holdup of small bubbles decreases with an increase of liquid viscosity.Meanwhile, the holdup of large bubbles decreases with increasing the system pressure.A correlation for the holdup of small bubbles was obtained from the experimental data.
Key words: Bubble column, Elevated pressure, Large bubble, Small bubble, Holdup
