Abstract
Continuous extractive distillation process for acetone-n-hexane azeotropic system was simulated and optimized using Aspen Plus V7.3.2.Methoxyethanol was selected as a suitable extractant.Through the orthogonal experimentation,the technologic parameter was optimized.The simulation result shows that the mass fraction of acetone and n-hexane can reach 99.60% and 99.63%,cyclic supplementation of ethylene glycol is 0.005kg/h while the number of theory stages is 34,the mixture feed stage is 27 th,the solvent feed stage is 8th,the reflux ratio is 1.2,and the solvent ratio is 2.5.The results are useful for the design and operation of continuous extractive distillation process for acetone-n-hexane azeotropic system.
