Modelling of Gas Separation in Thermally Rearranged Polymeric Membranes
During the last few decades, important progress has been achieved in both materials research and processing of device technologies. Individually, these efforts have already had an impact on process design and the modelling and process performance. In particular, membrane processes are change agents that promote a more sustainable and higher global standard of living. The development of advanced membrane technologies and the industrial application of polymeric membranes require good understanding of the materials properties and their transport mechanisms, as well as the realisation of innovative functional materials with enhanced properties. Thermally rearranged polymers show impressive performance for important applications such as gas separation. The reason lies in their microporous structure with enhanced rigidity. In addition, owing to their good scalability, these materials will enable the next step in molecularly selective membranes. The rapid improvement in numerical simulations and modelling methods and algorithms, together with the continuous increase in computer speed and increasing improvements in supercomputer architectures, accelerate research and development efforts by contributing to the improvement of materials research and process design and optimisation.
