Distillation is one of the most used separation processes in chemical industry, although it is a highly energy-intensive operation. For multicomponent distillation, complex structures have been proposed in previous works, which may allow energy savings. Nevertheless, it is mandatory to understand the dynamic characteristics of such complex structures. In this work, the dynamic performance of a dividing-wall-based structure for the separation of a five-component mixture is studied. A sensitivity analysis is performed on the structure in terms of the inter-linking streams, performing a singular value decomposition analysis to selected cases with different operational conditions. The designs with the lowest energy duties also showed the best open-loop properties.
