n-Propanol, as an important chemical raw material, is used as a solvent and intermediate in chemical industrial production and drug synthesis. In chemical production, alcohol and water easily form an azeotrope which is difficult to separate. In this work, a method of dehydration of n-propanol by pervaporation-assisted extractive distillation is proposed. Glycerol is selected as entrainer by quantum chemical calculation. A combined pervaporation unit with cellophane as a membrane is designed to separate the entrainer and water. The pervaporation unit is developed by using the Aspen Custom Modeler. Based on the minimum total annual cost, the extractive distillation process, feed-preheating extractive distillation process, and pervaporation-assisted extractive distillation process are optimized. The results show that the total annual cost of pervaporation-assisted extractive distillation is minimum and can reduce the total annual cost by 21.25%, compared with extractive distillation. Life cycle analysis is used to evaluate the environmental impact of processes. The results of environmental performance evaluation show that the pervaporation-assisted extractive distillation has the least environmental impact. Thus, the integration technology of membrane and distillation is of great significance in the sustainable process of chemical design and development.

“…Although SiC foam structured packing performs well in distillation, there are still some shortcomings: larger density, complicated preparation method, high cost, and difficult recycling . Therefore, we concentrate on the reticulated cellular structure which is essential for this study and on finding a suitable carbon foam material.…”

Carbon foam was utilized to develop corrugated structured packing in distillation for the first time. The hydrodynamics and mass transfer performance of CFP-400X and CFP-500W with 60 and 75°corrugation angle were determined by total reflux experiments. The results indicate that increasing the corrugation angle will improve the capacity but decrease the mass transfer efficiency. Comparisons among CFP-400X, SCFP-500X, BX-500, and B1-500X were made with respect to the performance of hydrodynamics and mass transfer. CFP-400X shows advantages in terms of capacity and efficiency compared with the other two metal packings. SCFP-500X exhibits a higher mass transfer efficiency than CFP-400X because of its superior wettability of test liquid which is supported by the liquid flow behavior experiment.
