The separation of olefin and paraffin is one of the most energy-intensive processes in petrochemical industry. Because of its similar boiling point and a low vapor pressure, the distillation column has above 150 tray inside and refrigerant cooling require to provide the heat duty in condenser. Nevertheless, there have been no other viable technology that can substitute the cryogenic distillation. In this study, we investigate the adsorption and membrane based process for the separation of propane and propylene. For the adsorption process, a dual-PSA process was developed to maximize propylene recovery and purity. It employs a kinetic selective MOF as an adsorbent. For the membrane process, a membrane-distillation hybrid process was developed using CMS. A mathematical model was constructed from the experimental data of adsorbent and membrane materials. A techno-economic analysis was conducted to elucidate the process feasibility from the conventional distillation process. |
