This paper proposes a novel extractive dividing wall distillation column, which has been designed using a constrained stochastic multiobjective optimization technique. The approach is based on the use of genetic algorithms to determine the design that minimizes energy consumption and total annualized cost. Several case studies are used to show the(More)
The optimal design of hybrid separation systems is a highly non-linear and multivariable problem, and the objective function (total annual cost, TAC) used as optimization criterion is generally non-convex with several local optimums. Particularly, genetic algorithms optimization methods are very attractive for engineering applications, due to its(More)

Design of reactive distillation sequences is a major computer-aided design challenge. The optimal design of reactive complex distillation systems is a highly nonlinear and multivariable problem, and the objective function used as optimization criterion is generally nonconvex with several local optimums and subject to several constraints. In addition,(More)
Dividing wall columns are intensified process equipment with the capacity of reducing both capital and operational costs for a given vapor−liquid separation, when compared with conventional distillation sequences. For some kinds of mixtures, distillation systems with two dividing walls have been theoretically proved to present lower energy requirements and(More)
The dividing wall column, DWC, is a thermally coupled sequence that can perform the separation of fluid mixtures with reduced energy consumption, but also decreasing the capital costs associated. Several authors have developed design procedures for this kind of sequence, using short methodologies or optimization strategies. The use of short procedures is(More)
Exxerpro Solutions, Av. del Sol 1B Interior 4B, In this work, two schemes are analyzed for the reduction on energy consumptions for ternary distillation: a Petlyuk column, PC, and a Petlyuk with postfractionator system, PCP. To perform the optimal design of the analyzed systems, the use of multiobjective genetic algorithms has been considered. Moreover, a(More)
