Abstract

This study presents a novel approach to the dehydration of n-propanol using three hybrid methods-D + HPV, D + HPV + D, and D + HPV + D with heat integration-each combining distillation (D) and hydrophilic pervaporation (HPV) without the use of additional solvent agents, as in the most common separation method, extractive distillation. The optimization was performed using a ChemCAD process simulator, targeting 99.9 wt% purity for n-propanol and water. This is the first research to provide a comprehensive cost estimation and carbon footprint analysis for such configurations. Results show the D + HPV + D + HI method provides the best balance of energy efficiency, environmental sustainability, and economic feasibility. It reduced heat duties by 18.5% compared to D + HPV + D, achieved similar CO2 emissions to D + HPV with better energy efficiency, and lowered the total annual cost by 37.9% compared to D + HPV. The findings establish D + HPV + D + HI as a promising technology for sustainable and cost-effective n-propanol dehydration.

n -丙醇-水混合物混合分离方法的环境评价:蒸馏和亲水渗透蒸发相结合。
本研究提出了一种使用三种混合方法(D + HPV, D + HPV + D和D + HPV + D)进行正丙醇脱水的新方法,每种混合方法都结合了蒸馏(D)和亲水渗透蒸发(HPV),而不使用额外的溶剂剂,如最常见的分离方法,萃取精馏。使用ChemCAD过程模拟器进行优化,目标是正丙醇和水的纯度为99.9 wt%。这是第一次为这种配置提供全面的成本估算和碳足迹分析的研究。结果表明,D + HPV + D + HI方法提供了能源效率,环境可持续性和经济可行性的最佳平衡。与D + HPV + D相比,它减少了18.5%的热负荷,实现了与D + HPV相似的二氧化碳排放,但能效更高,与D + HPV相比,年总成本降低了37.9%。研究结果表明,D + HPV + D + HI是一种具有可持续发展和成本效益的正丙醇脱水技术。
