Abstract

Feasibility of batch extractive distillation in rectifying column with middle boiling entrainer is studied. Separation of methyl acetate and cyclohexane (forming minimum boiling azeotrope) using carbon tetrachloride, and separation of chloroform and ethyl acetate (forming maximum boiling azeotrope) using 2-chlorobutane are theoretically studied based on profile maps and rigorous simulation. Non-extractive distillation with pre-mixing the entrainer to the charge is also studied in both cases. Feasibility of the processes are demonstrated with laboratory-scaled experiments. Versions of BED according to the types of the azeotrope and of the entrainer are compared; and the decisive properties are pointed out.
