Characterization of a New Flat Sheet Membrane Module Type for Gas Permeation

Abstract

Modern high‐performance flat sheet gas separation membranes exhibit high permeances as well as high selectivities, e.g., for CO2 separation. Novel membrane modules are desirable to transfer the intrinsic membrane performance to the process. The introduced module implements countercurrent flow, which allows for the best utilization of the required driving force, provided concentration polarization and pressure drops can be kept at bay. As such, it is different from established flat sheet modules for gas separation. The design features allow for straightforward scaling and easy adjustment to other operating conditions. During module development equation‐oriented modeling, computer‐aided engineering design and application of computational fluid dynamics for flow optimization were integrated. The prototype was investigated in a pilot plant. The experimental results reflected the simulation predictions and proved the validity of the module concept.

Hollow Fiber Membrane Contactors for Post-Combustion Carbon Capture: A Review of Modeling Approaches

“…Summary of common membrane materials used in hollow fiber membrane contactors (HFMCs) for CO 2 separation from flue gas. Polypropylene (PP) [14,22,25,26,33] Polytetrafluoroethylene (PTFE) [15,21,34] Polyvinylidene fluoride (PVDF) [19,22,25,29,[35][36][37] Polymethylpentene (PMP) [19] Carbon capture membrane contactors come in many configurations: tubular/hollow-fiber [38], spiral wound [39], and flat sheet [40]. A common geometric configuration used in PCC is the hollow fiber membrane contactor (HFMC), and this particular design will be the focus of this review paper.…”
