Hydrodynamic Considerations in an External Loop Airlift Reactor with a Modified Downcomer [PDF]
Gas holdup and superficial liquid velocity in the downcomer and riser are studied for an external loop airlift reactor with a downcomer-to-riser area ratio of 1:16. Two downcomer configurations are investigated over a range of superficial gas velocities (

Effect of Electrolyte Concentration on Bubble Size and Gas-Liquid Interfacial Area in Bubble Column
The optimum conditions of bubble column would be the ones that enhance mass transfer and this is accomplished by maximizing gas-liquid interfacial area. In the present work the effect of electrolyte concentration (aqueous solution of sodium chloride NaCl
