A Generalized Methodology for Optimal Configuratons of Hybrid Distillation-pervaporation Processes
The aim of this work is to illustrate the structural and parametric optimization of continuous hybrid distillation-pervaporation process with different configurations such as series, parallel, and series-parallel arrangement of pervaporation modules in the pervaporation network, and to propose a generalized methodology for difficult separations. A superstructure representation of hybrid process...
متن کاملHybrid Pervaporation-absorption for the Dehydration of Organics
A novel configuration of pervaporation and vapor permeation processes is introduced. In the suggested process the driving force for permeation is enabled by the absorption of the permeate vapors using a suitable solvent with a low vapor pressure. Thus, the refrigeration needed for condensing the permeate under vacuum can be overcome and cost savings can be achieved. Moreover, very low vacuum pr...
متن کاملModeling of pervaporation processes controlled by concentration polarization
Pervaporation is considered a clean and energetically efficient process used for a wide range of applications, working separately or integrated nto a hybrid process. In this work, a mathematical model has been developed accounting for the mass transport phenomena under non-isothermal onditions with strong contribution of polarization concentration that prevail in pervaporation systems. The math...
متن کاملTransesterification Processes by Combination of Reactive Distillation and Pervaporation
The development of a reactive distillation process for the production of n-butyl acetate by transesterification of methyl acetate with n-butanol is presented. Thermodynamic aspects of the quaternary system n-butyl acetate – n-butanol – methyl acetate – methanol are discussed and UNIQUAC interaction parameters derived using the Dortmund Data Bank (DDB) are given. The reaction kinetics of the het...
متن کاملDevelopment of a Scale-up Tool for Pervaporation Processes
In this study, an engineering tool for the design and optimization of pervaporation processes is developed based on physico-chemical modelling coupled with laboratory/mini-plant experiments. The model incorporates the solution-diffusion-mechanism, polarization effects (concentration and temperature), axial dispersion, pressure drop and the temperature drop in the feed channel due to vaporizatio...
