PVFC与萃取精馏工艺回收高纯度糠醛的流程模拟及能量对比分析
Simulation and Energy Analysis of PVFC Process for Recovering Furfual with High Purity
摘要
Abstract
Pervaporation-fractional condensation(PVFC)is a new type of coupling process de-veloped for high purity recovery of high boiling organic compounds in low concentration aqueous solutions.On the basis of experimental data,the thermodynamic processes of PVFC and tradi-tional extractive distillation were analyzed by the model of non-random two liquid(NRTL)within the Aspen Plus software,with the emphasis on the influence of operating temperature on the product quality and yield,as well as the energy consumed by the two kinds of processes.The mechanism of obtaining high purity furfural by the PVFC process was also revealed.The results show that the energy consumption by the PVFC process was only 50% of that by the extractive distillation process.However,the purity of the product by the PVFC process,99.9%(experi-mental value),was higher than that by the extractive distillation process,97%.Compared with the traditional process,the PVFC coupling process needs less unit equipments,not only saving energy consumption but avoiding the use of extracting agent also.Therefore,it is a good applica-tion for high purity recovery of high boiling point organic compounds which are easy to form azeo-tropic system.关键词
