Optimal Design Methodology for Azeotropic Distillation Columns
نویسندگان
چکیده
We develop a short and optimal design methodology for multicomponent mixtures, based on the concept of minimum difference in composition. The minimum reflux ratio is calculated through an analytical procedure, which allowing their use in multicomponent mixtures. The procedure also includes a simple criterion to optimize the structural design of the column, without increasing energy consumption. The method is tested with different azeotropic mixtures, and it is compared with the results of a multiobjective genetic algorithm with constraints. Results show that designs obtained with the new and stochastic methods are quite similar, but less time and computational resources are required.

Effect of adjusted parameters of NRTL model in design, optimization, and control of homogeneous azeotropic distillation columns
In this work we use adjusted parameters obtained with Simulated Annealing and those from Dechema Collection [1] for the NRTL model, in order to analyze their effect in the design, optimization, and control of homogeneous azeotropic distillation columns. For the design of the azeotropic sequences we use short design methodologies [2, 3], while a multiobjective genetic algorithm with constraints ...
متن کاملSimulation of Ethanol Extractive Distillation with Mixed Glycols as Separating Agent
Extractive distillation is an alternative for ethanol dehydration processes that has been shown to be more effective than azeotropic distillation and, in close proximity, to be very competitive against the process that uses adsorption with molecular sieves. Glycols have been shown to be the most effective solvents in extractive distillation, mainly ethylene glycol and glycerol. In this work, an...
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 کاملThe importance of the sequential synthesis methodology in the optimal distillation sequences design
The sequential design method is presented as a complementary tool of the systematical synthesis procedure that allows to define a clear connection among the different types of distillation column sequences. In particular, the connection with the simple column subspace is considered, since this subspace represents the comparison reference for all the alternatives considered. The sequential desig...
متن کاملCombining Shortcut Methods and Rigorous Minlp Optimization for the Design of Distillation Processes for Homogeneous Azeotropic Mixtures
For the separation of azeotropic mixtures with distillation usually a number of conceptual design alternatives are generated. Instead of evaluating the economic viability of the different alternatives by repetitive simulation studies, a combination of shortcut calculations and rigorous MINLP optimization is proposed. In this two step process the shortcut calculations are used to screen and rank...
