Abstract

Efficient distillative separation of an at least three component mixture containing high boiler, medium boiler and low boiler components is accomplished by interposing a column having a stripping section and a rectifying section separated from each other by a horizontal impermeable dividing wall between conventional distillation columns. High efficiency and low capital cost is achieved.
