The liquid velocities and gas holdups in the riser and downcomer of three-phase internal-loop airlift reactors with Newtonian and non-Newtonian fluids were studied. The reactor was constructed of 19 cm ID Plexiglas column and 250cm in height. The inside diameters of the draft tube were 9, 12, and 14
## Abstract Liquid velocity and gas holdup were measured in a 690L pilotβscale rectangular airlift contactor, divided into aerated and nonaerated sections by two vertical rectangular polyester textile membranes. Horizontal flow through the porous membranes complicates flow fields to such an extent
## Abstract The effects of the horizontal connection length (0.1 Β± __L~e~__ Β± 0.5 m), the crossβsectional area ratio of downcomerβtoβriser (0.11 Β± A~d~/A~r~Β± 0.53), and the superficial gas velocity on gas phase holdups in the riser and downcomer were studied. The circulation liquid velocity, the mi
Liquid velocity and gas holdup in three-phase internal loop airlift reactors were investigated. Air and water were used as the gas and liquid phase, respectively, and the solid particles used were calcium alginate beads with different particle size. The liquid velocity in the riser and the downcomer
