- Abstract: This paper presents a new unified model that allows the simulation of distillation columns with any integer number of phase divisions. Such columns have the potential for substantial savings in energy and capital costs. However, conventional simulators do not cover columns with phase divisions and previous simulations required a tailored algorithm for each type of column. The proposed model uses a unique set of MESH-equations for parastillation, metastillation, and conventional distillation. With small modifications in the stage indexing, the model allows the simulation of conventional, top and bottom-DWCs. This generalization was possible by introducing two new variables: the number of liquid (θ) and vapor (β) phase divisions. The positive impact of increasing the number of phase divisions was demonstrated in the bioethanol distillation, by analyzing parastillation and metastillation columns. These columns reduce the operational and total annual costs in 19% and 15%, when compared to conventional columns.
