Abstract
The autoextractive distillation of an azeotropic solvent mixture of acetone, chloroform, n-butanol, and dimethylformamide is considered. A set of flowsheets belonging to different structural classes is synthesized (flowsheets containing two-withdrawal columns and flowsheets involving complex columns with a single side section). The flowsheet that is optimal in energy consumption is revealed, and it is shown that flowsheets with coupled heat and material flows are more efficient than conventional ones.
