Arne Lindbråthen

Arne Lindbråthen is a Researcher in the Department of Chemical Engineering at the Norwegian University of Science and Technology (NTNU), Faculty of Natural Sciences. His work centers on membrane technology development for gas separation applications, with focus on CO₂ removal from flue gas, biogas, and natural gas streams, as well as natural gas dehydration and hydrogen purification.

His research interests span membrane technology development, carbon capture, and gas separation processes. Lindbråthen specializes in manufacturing carbon molecular sieve membranes, from polymer solution optimization to pilot-scale testing. His work integrates materials science with process engineering for applications in carbon capture, biogas upgrading, and hydrogen purification. Key focus areas include membrane stability under harsh conditions (H₂S, moisture), techno-economic assessments, and scaling lab innovations to industrial pilots.

Lindbråthen's publication record shows strong collaboration with the MEMFO research group, particularly with Liyuan Deng, Linfeng Lei, and May-Britt Hagg. His work demonstrates consistent contributions to CO₂ separation membrane development since the early 2000s, with recent emphasis on moisture-swing adsorption, mixed matrix membranes, and field trials in industrial settings like cement plants. His research bridges fundamental membrane science with practical engineering solutions for decarbonization.

His laboratory work includes pilot-scale production of carbon hollow fiber membranes and testing under high-pressure, high-temperature conditions. The MEMFO group, where he is active, maintains long-term focus on reducing carbon emissions through membrane-based separation technologies, with documented field trials in demanding industrial environments.
