Abstract
Systems and methods are provided for improving the operation of a divided wall column for performing distillations. The systems and methods include using a separation stage in a fluid flow pathway for transporting an enriched intermediate stream from a first side of a dividing wall to a second side of a dividing wall. By using a separation stage, the benefit of transporting an enriched intermediate stream can be achieved without requiring precise knowledge of the local concentration profile on the first side of the dividing wall.
