Mass transfer and kinetics in ethoxylation spray tower loop reactors

A mathematical model has been developed for describing the behaviour of the spray tower loop reactors. Th reactors are characterised by the fact that mass transfer and reaction occurs independently in two distinct zone of the reactor. The model has been used for simulating the performance of a pilot plant both by assuming liquid drops internally stagnant and turbulent. The last assumption gives the better results.
