Abstract (EN):
This paper extends the algorithm previously developed by the authors (Ribeiro et al., Comp. Chem.
Engng 19, 333, 1995b) to the simulation of the full trivariate (drop volume, age and solute concentration)
unsteady-state behaviour of interacting liquid-liquid dispersions, in continuous or batch stirred vessels. The
algorithm uses Coulaloglou and Tavlarides (1977) drop interaction model, but it may easily accommodate any
alternative models. Both rigid and oscillating drop mass transfer behaviour have been tested. The procedure
enables to simulate in detail all relevant aspects of the dynamics of interacting dispersions in mass transfer
conditions, namely the gradual approach to steady-state and the response to pulse and step changes in the main
process variables. The algorithm's speed is high, allowing to envisage its future application in the control of mass
transfer contacting equipment, with only modest computer resources.
