Abstract
Hydrodynamics in the downcomer of a high Liquid holdup airlift tower loop r eactor, whose riser has been previously studied, is presented. A visual pro cedure with colorimetric tracers injected into the top part of the riser an d monitored by means of a video camera system, for subsequent treatment of the obtained images, was used. The tracer front advance curves have suggest ed a compartmental model of three parameters to be used for physical transp ort processes. (C) 2000 Society of Chemical Industry.
