The present study investigated the feasibility of bioCO(2) sequestration using Chlorella sorokiniana. It was found that 5% CO(2) (v/v) in air was the most suitable concentration for the growth of this organism. At this concentration, the maximum rate of CO(2) sequestered and the biomass obtained were found to be 1.21 g L(-1)d(-1) and 4.4 g L(-1) respectively. Modeling and simulation of the grow...

Mixing has been one of the important parameters in characterizing and designing external air-lift bioreactors for the biological processes that require intensive mixing for mass transfer. In this study, pH tracer method was employed to characterize the mixing quality of a three-phase laboratory-scale external-loop air-lift bioreactor (EALR) used for cultivation of a pelletized filamentous funga...

INTRODUCTION Multi stage distillation processes are normally operated in columns, equipped with trays or packing to obtain counter current flow of vapour and liquid. In tray columns the liquid is moving from the inlet over the active area to the exit downcomer. The necessary mass transfer area between the phases is achieved by intense mixing of vapour and liquid on the bubbling area. In packed ...

The pressure drop for air-water two-phase flow in pipeline systems with S-shaped and vertical risers at various inclinations (−1°, −2°, −4°, −5° −7° from horizontal) was predicted using an artificial neural network (ANN). In the designing of ANN model, superficial velocity gas liquid as well inclination downcomer were used input variables, while values flows determined output. An a hidden layer...

A suitable initial point for understanding multiphase flows is a phenomenological description of the mechanism geometric distributions or flow patterns that are observed. The challenge however prediction combination operating conditions and characteristics phases as well points transition from one pattern to other. Different occur in different pipeline configurations which U-shape risers part. ...
