Influence of the baffle clearance design on hydrodynamics .

2006-8-1 · The relative contribution of the riser and downcomer to the separator and/or total gas holdups are different and complementary. The main term ((U gr)/(gD hc) 0.5), which represents the influence of gas input rate and the liquid circulation rate, affects the holdup more strongly in the downcomer than in the riser.

Hydrodynamics and mass transfer characteristics in an .

The gas holdup in the riser was only marginally affected by the design of the separator; however, the relationship between the riser and the downcomer holdups was sensitive to separator configuration.

Replaced by Suprafilt 9inch diffuser Growing algae in the lab Internal of the ALB The gas separator section links the riser to the downcomer at the top, permitting gas disengagement and recirculation of fluid. Consequently, this drives a flow from the top of the riser to the bottom.

Airlift Bioreactors - an overview | ScienceDirect Topics

Airlift bioreactors are quite similar to the stirred tank reactors, except for the impeller. This is a gas liquid bioreactor which is based on the draught tube principle. In this reactor compressed air is used for aeration and agitation. Usually the hairy roots require 0.05–0.4 vol of air/vol of liquid/min oxygen supply for optimum growth.
