الملخص EN

The effects of vertical cooling internals on the gas hydrodynamics was studied in gas-liquid system (bubble columns) for column diameters, 15 and 30 cm in the absence and presence of internals (the % occluded area by internals 5, 10, and 20 %).

The superficial gas velocity was varied in the range 0.8-30 and 0.8-7.6 cm/s for 15 and 30 cm column diameters respectively.

The effect of internals on the bubble dynamics in columns was assessed using the electroresistivity probe technique.

The overall gas holdup is measured experimentally by bed expansion technique.

The experimental results show that the increased in percentage coverage of cross sectional area by internals causes an increase in the overall gas holdup values, gas holdup radial profiles, bubble rise velocity, bubble frequency and reduce average bubble diameters.

Correlations have been used for the estimation of the gas holdup in gasliquid system bubble column.

The overall gas holdup can be easily predicted from 1.516 0.
