摘要

Tetrahydrofuran and water formed a minimum azeotrope at 64°C,which contains water 6.7% in mass fraction.We could not use conventional distillation to separate these two components.In this work,a systematic study of the separation of the tetrahydrofuran-water mixture with a new entrainer by batch extractive distillation was performed.Based upon the lots of computation,1,2-propanediol was chosen to be the entrainer.It broke the original binary azeotrope.The process feasibility analysis was validated by rigorous simulation with chemical process simulation software-HYSYS.Plant 2.2 and DISTIL 4.1.Simulation results were then corroborated in a batch experimental packing column with the selected entrainer.The experimental and simulation results agreed well.
