Carbon molecular sieve (CMS) membranes offer advantages over traditional polymeric membrane materials, but scale‐up of manufacturing systems has not received much attention. In the recent decade, there has been a dramatic increase in fundamental research on these materials with a variety of applications being studied. The results from a pilot‐scale CMS production system are presented. This system was designed based on extensive laboratory research, and hollow fiber membranes produced in this system show similar performance compared to membranes produced using a smaller bench‐scale system. After optimizing the system design, a 93 % recovery of the precursor fibers for use in membrane module preparation were obtained.
