Abstract
The utilization of membranes for gas separation processes has gained momentum due to its numerous advantages. This article focuses on the separation of gases, with a particular emphasis on the critical CO2 and CH4 separation. Membrane-based separation offers cost-effective solutions and easy scalability compared to other technologies. This research delves into the relatively unexplored domain of using membranes for gas separation in supercritical conditions. The study investigates the influence of geometric parameters on membrane modules using Computational Fluid Dynamics (CFD) modeling and simulations, employing the finite element method in the commercial software COMSOL. The Soave-Redlich-Kwong real gas model was used within the software. The findings suggest that temperature plays a crucial role in expediting the process. However, in supercritical conditions, the separation efficiency might be compromised. Surprisingly, many of the geometric parameters were found to have limited relevance. These findings contribute to a deeper understanding of membrane-based gas separation in supercritical conditions and shed light on the significance of various parameters involved in the process.
