摘要：

For most separations, a fully thermally coupled distillation column or divided wall columns are thermodynamically more efficient than conventional columns. This paper develops a method for the design of divided wall columns consisting of multi-component mixtures (more than three components) with constant relative volatilities and a relatively sharp separation between the key components.
