“…The selection of such complex configurations depends strongly on the separation problem, i.e., composition, thermal condition of the feed, specification of the products, and relative volatilities of the components. Therefore, the development of simple and efficient design algorithms for the determination of all relevant design parameters under pinch conditions in a complex distillation column, with takes into account all previously mentioned separation parameters, constitutes an important step towards the development of a reliable approach for the evaluation of different distillation sequence alternatives involving complex configurations .…”

Dynamic Performance of a Complex Distillation System to Separate a Five‐Component Hydrocarbon Mixture

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 interlinking 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.
