This thesis addresses the steady state modeling of perforated plate extraction columns conducting purely physical extraction and extraction accompanied by a slow chemical reaction taking place between the solute and an excess of a reagent in the solvent phaseDistributed parameter models are derived for each stage assuming complete back mixing of the continuous phase between two plates and plug flow of the counter currently flowing dispersed phase dropletsFollowing the integration of the model describing the evolution of the dispersed phase composition within each plate , the model has been generalized to express the behaviour of a multi - stage tower with respect to the cases of physical extraction and extractive reaction taking place in the dispersed phase
