Abstract

Abstract: The gas and dispersed phase holdups and mass transfer coefficients of liquid-iquid were
determined for gas-liquid-liquid three phase system in a screen plate column. The flow
pattern of gas-liquid-liquid three phase system was studied under different gas velocities.
The shape factors showed the geometric properties of screen plates and the corrected drop
characteristic velocities were introduced. The phase holdup in two phases was correlated.
The research results indicated that mass transfer coefficient for liquid-liquid system in a
column with screen plates and gas agitation was found to increase apparently.

Key words: Gas-liquid-liquid systems, screen plate, holdup
