Conceptual Design of Reactive Distillation Columns with Non-Reactive Sections
Reactive distillation has received intense attention due to the well known benefits of integrating distillation with reaction in a single unit. While there are procedures available for the synthesis of non-reactive columns and of reaction-separation systems, the design of reactive distillation columns is still a challenge. This work presents a new synthesis and design methodology for reactive d...
متن کاملDesign optimization of reactive distillation columns by memetic algorithms
Design optimization problems in chemical engineering and in many other engineering domains are characterized by the presence of a large number of discrete and continuous decision variables, complex nonlinear models that restrict the search space, nonlinear cost functions, and the presence of many local optima. The classical approach to such problems is the use of MINLP solvers that work on a su...
متن کاملConceptual Design of n-Butyl Acetate Synthesis Process by Reactive Distillation Using Residue Curve Maps
Residue curve maps are a powerful tool for the preliminary design of Reactive Distillation (RD). In this study, residue curve maps of the n-butyl acetate synthesis reaction were calculated based on the Langmuir–Hinshelwood–Hougen–Watson kinetic and UNIQUAC models to calculate the physical properties of the system. The results showed that the unstable node branch emerged from the n-butyl ace...
متن کاملUsing Thermally Coupled Reactive Distillation Columns in Biodiesel Production
Production of ethyl dodecanoate (biodiesel) using lauric acid and methanol with a solid acid catalyst of sulfated zirconia is studied by using two distillation sequences. In the first sequence, the methanol recovery column follows the reactive distillation column. In the second sequence, the reactive distillation and methanol recovery columns are thermally coupled. Thermally coupled distillatio...
متن کاملA Memetic Algorithm for the Design Optimization of Reactive Distillation Columns
This contribution deals with the optimization of the design of reactive distillation columns by using a memetic algorithm (MA) which is a combination of an evolution strategy (ES) and a mathematical programming (MP) solver. The standard approach to solve such problems is to formulate them as large MINLPs but then the computational effort needed for the solution process grows substantially if th...
