Unlocking the Benefits of Hybrid and Standalone Pervaporation for Sustainable Isopropanol Dehydration with HybSi^® AR Membranes.

ABSTRACT: This study presents the first combined techno-economic and environmental analysis of IPA dehydration using HybSi® membranes across three configurations, offering a low-emission alternative to conventional azeotropic distillation. The processes are simulated in Aspen Plus, and include two hybrid separation processes (i.e., distillation-pervaporation and distillation-pervaporation-distillation) and one standalone pervaporation process. The pervaporation module uses data from experiments that were performed using HybSi® AR membranes at 130 °C and two vacuum pressures (20 and 50 mbar). The separation processes were systematically compared using a comprehensive set of performance indicators covering technical, economic, and environmental aspects. A new cost-efficiency metric, COPCO, is introduc
