Considering that three-phase dispersions are common in chemical engineering and biotechnology, and with increasing airlift reactor applications to chemical and biotechnological processes, a experimental study was undertaken in order to investigate th

The paper concerns with mass transfer in liquid–liquid extraction, considering that the experimental determination of the individual mass transfer coefficients during liquid–liquid extraction is still considered to be a difficult problem. In this

The paper presents a model of the motion of a particle subjected to several transport processes in connection with mixing in two phase flow. A residence time distribution technique coupled with a one-dimensional dispersion model was used to obtain th

The residence time distribution (RTD) analysis of liquid phase was performed in a concentric-tube airlift reactor of 0.07 m3 nominal volume, regarded as a simple unit and discriminating its different sections (riser, downcomer, bottom zone and gas-li

A mathematical model for riser liquid superficial velocity in a concentric-tube airlift reactor is proposed. The model is based on an energy balance incorporating acceleration coefficients to quantify deviations from ideal flow. The acceleration coef

The mixing behaviour of the liquid phase in two external-loop airlift reactors of laboratory and pilot scale, in terms of the mixing time and axial dispersion, was investigated. The mixing parameters were determined from the output curves to an initi
