Abstract

and optimization work was performed using benzene as an entrainer to obtain a nearly pure an-hydrous isopropyl alcohol product from dilute aqueous IPA mixture through an azeotropic distillation process. NRTLliquid activity coefficient model and PRO/II with PROVISION 6.01, a comercial process simulator, were used toand the concentration of IPA at concentrator top as a manipulated variable. As a result, 38.7 mole percent of IPA atconcentrator top gave the optimum value that minimized the total reboiler heat duties of the three distillation columns.
