The adoption of membranes for gas separation processes has gained considerable traction owing to their numerous advantages. This work focuses on gas separation and how it can be modeled. Membrane-based separation presents cost-effective solutions with easy scalability compared to alternative technologies. This research explores the relatively uncharted territory of employing a fiber-scale model to study the separation process. It investigates the influence of geometric parameters, flow configurations, and different membrane materials on membrane fibers using Computational Fluid Dynamics (CFD) and employing the finite element method in the commercial software COMSOL. Additionally, the Soave-Redlich-Kwong real gas model was incorporated into the software. The model was first validated with experimental values found in the literature, ans subsequently employed to investigate different aspects of the separation phenomenon. Some of the studied geometric parameters proved to be insignificant for the process efficiency. Regarding flow configurations, the results showed that the process can be improved by increasing the pressure difference between the permeate and feed, and counter-current flow can be used to enhance separation in larger stage cuts. Furthermore, other membrane materials were studied, and it was noted that there is a significant difference between the results, requiring further studies on specific materials to ascertain their positive and negative points. These findings deepen our understanding of membrane-based gas separation in supercritical conditions, shedding light on the significance of various parameters involved in the process. (AU) | |
