SEPARATION OF DIISO-PROPYL ETHER+ISO-PROPANOL+N-PROPANOL BY EXTRACTIVE DISTILLATION AND PRESSURE-SWING DISTILLATION:SIMULATION AND ECONOMIC OPTIMIZATION
We have studied,simulated and evaluated economically two separation alternatives of a ternary mixture made up of 25 mol%diisopropyl ether,60 mol%isopropyl alcohol and 15 mol%n-propyl alcohol by means of a practical case of a plant to treat 100 kmol/h.The simulation has been carried out satisfactorily by mean of a package of commercial software Aspen Plus using the thermodynamic model NRTL-RK.The extractive distillation using N,N-dimethyl acetamide as a solvent and pressure-swing distillation have been optimized independently and the best configurations have been evaluated economically.Results show that,for this particular case,the pressure-swing distillation is more attractive.
