Optimal Design of Extraction Processes by Gradient Methods

抄録
This paper deals with the optimization problem of extraction processes with recycle and immiscible solvent. Gradient methods using control variable iteration require a trial and error procedure to solve process and overall equations for this problem. A new formulation is presented to eliminate such a trial and error procedure. First order and second-order convergence gradient methods were applied to determine the optimum solvent distribution in cross-current extraction with recycle and immiscible solvent. The Fletcher-Powell method converged most rapidly in all cases.
