Abstract
The capacity of a solvent extraction process is dependent on the solvent power and the selectivity of the solvent for the feed solution to be treated. In this article the effects of imposing a temperature profile on an extraction process are analyzed in detail with the object of increasing the solvent power and selectivity of a solvent toward a certain solute. A mixer-settler arrangement is assumed for the countercurrent stage-wise extraction process on which a temperature gradient is applied. A mathematical model was formulated for the mixer-settlers. A computer program was devised, and data obtained for the discrete maximum principle which can be applied successfully to optimize stage-wise countercurrent extraction processes. It is demonstrated that the discrete maximum principle can be applied to optimize countercurrent extraction processes but the original objective function, as well as the fictitious one, the Hamiltonian, must be checked for the optimum.
