Designing packed multi-partition wall dividing wall columns

Separation of three-component mixtures into three pure products using a dividing wall column (DWC) is an established energy, capital and space saving distillation technology with ever growing number and field of applications. This paper addresses potential and possibilities for four or more products separations that could increase potential gains and most importantly, could be arranged in an industrially viable way using packed, multi partition DWCs. This paper addresses possibilities and peculiarities associated with establishing the most beneficial internal configuration of a complex DWC for separation of a multycomponent aromatics mixture into four or five product streams by using V-min diagram method to identify most promising configurations and to provide initial values for detailed simulation based determination of adequate energy and stage requirement.
