Abstract

The present state of the art in the experimental determination of mass transfer coefficient in Air Lift Reactors is reviewed. A Criterion which allows to decide whether the assumption of perfect mixing of the liquid phase is valid was experimentally verified. For the cases where such assumption does not hold, a new method that renders local values of KLa in each of the regions of the reactor (riser, downcomer and gas separator) is presented. The model is based on a fluid dynamic structred model of the system.
