Mass transfer limitations in syngas fermentation processes are mostly attributed to poor
solubility of CO and H 2 in water. Despite these assumed limitations, a syngas fermentation …

The effects of different spargers on the hydrodynamics and mass transfer of an airlift loop
reactor were investigated. The gas holdup, liquid loop velocity, and volumetric mass transfer …

This study investigated the effect of sparger designs on a D-shape hybrid airlift reactor
(DHALR) performances. The designs of airlift and torus reactors were combined to get the …

In the present study a novel type of internals, self‐agitated impellers, were inserted in the
riser section of an external‐loop airlift reactor to intensify mass transfer rates. The …

The average shear rate (γ˙ av) is a parameter used to characterize the shear environment in
bioreactors, enabling comparison of the performances of different bioreactor models in terms …

In a pilot-scale internal loop airlift reactor with a height of 5.5 m and a main column diameter
of 0.484 m, the influence of three gas sparger structures (ladder distributor, tri-nozzle …

Useful correlations were derived for the prediction of available gas holdup data in air-water
systems, using the operational and geometric parameters of airlift reactors only. To …

Three designs of static spargers were used in a pilot scale external loop airlift reactor to
determine their effects on the gas holdup and mass transfer characteristics for an air-water …

For modeling, design and scale-up of the airlift reactors, it is crucial to estimate
hydrodynamic parameters and volumetric gas–liquid mass transfer coefficient for different …

In airlift systems, the difference in gas holdup (εg) between the riser and the downcomer
creates the driving force for liquid circulation. This feature can be an interesting approach to …
