Systematic Synthesis of Dividing-wall Columns for Multicomponent Distillations
Abstract Dividing-wall columns(DWC) are intensified distillation systems for multicomponent separations. They have the potential to save both energy and capital costs significantly than conventional simple column configurations. The several DWC columns for ternary distillations have been figured out by some creative activities from different inventors. Recently they have gained the momentum to ...
متن کاملDividing wall columns for heterogeneous azeotropic distillation
The aim of this work is to implement heterogeneous azeotropic distillation schemes in a dividing wall column (DWC) for a feed mixture of water (W), acetic acid (HAC) and an organic component (X). The original design makes use of X to act as an entrainer to facilitate the separation of water and HAC, and we also propose a DWC design based on this idea. This DWC design reduces the capital cost, b...
متن کاملOptimal Design Methodology for Dividing Wall Columns
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 easy and fast, but, in the most of the c...
متن کاملOptimal Designs of Multiple Dividing Wall Columns
Since the optimal design of dividing wall columns (DWC) is a highly nonlinear and multivariable problem, an appropriate solving tool is required. In this paper a multi-objective genetic algorithm with restrictions is considered to design columns with dividing walls. Also, a methodology is proposed for sizing the DWC. The proposed design methodology allows achieving appropriate designs for colum...
متن کاملControl of Dividing-Wall Columns via Fuzzy Logic
Because of their potential energy savings, dividing-wall columns (DWCs) have been viewed as an interesting alternative to the use of sequences based on conventional distillation columns. The energy savings, however, must be supported by suitable controllability properties for a proper operation. In this study we use a design methodology to optimize the gains of the Takagi−Sugeno fuzzy controlle...
