Coupling between extraction, reaction, and liquid-liquid contact
hydrodynamics have quantitative as well as qualitative implications
on the performance of un-agitated perforated plate
extractive reactors. Models, which take into account the effect of
flow dynamics on mass transfer performance, are developed to
analyze the steady state behavior of such columns when conducting
a chemical reaction in the continuous extract phase. New
expressions are derived for the composition profiles in the cases
of physical extraction, slow, and infinitely fast reactions. Typical
results show that the raffinate purity may either increase or
decrease on increasing the solvent rate depending on the interaction
between column fluid dynamics, mass transfer, and reaction
kinetics
