(156b) Iimar (Intensified Integrated Membrane- Adsorptive Reactor) for Simultaneous Carbon Capture and Hydrogen Production

Minimizing carbon dioxide emissions is critical, hence the importance of carbon capture-storage (CCS) technology, which is highly effective at reducing carbon emissions, has grown. The importance of carbon capture-storage (CCS) technology, which is extremely effective in reducing carbon emissions, has grown. On the other hand, hydrogen is a key energy carrier for storing and transmitting energy, and hydrogen-based technologies are becoming more promising as the globe shifts toward a more ecologically friendly approach. Nonetheless, incorporating CCS technology into power production processes is a substantial problem that necessitates the improvement of the combined power generation-CCS process. In recent years, there has been a surge of interest in process intensification (PI), which seeks to build smaller, cleaner, and more energy efficient processes. The purpose of this study is to demonstrate the process intensification potential by modelling and simulating a iiMAR process for simultaneous carbon capture and hydrogen production. A complete, multi-scale, multiphase, dynamic, computational fluid dynamics (CFD)-based process model is developed, quantifying the numerous underlying complicated physicochemical phenomena happening at the pellet and reactor scales. Model simulations are then run to determine the impact of dimensionless variables on overall system performance and to acquire a better understanding of the cyclic reaction/separation process.
