Problem 9 A traditional way to separate compounds in an azeotropic mixture is to use azeotropic or extractive distillation, where a mass separating agent (MSA) is added to a first distillation column to break the azeotrope, followed by a separator and a second distillation column. Another alternative is to use a separation train consisting of a distillation column followed by vapor permeation (see Figure bellow). Based on the principles of green chemistry and green engineering, which system is 'greener' and why
