Recent advances, challenges and perspectives on rotating packed bed technology in solvent-based post-combustion carbon capture

Rotating packed beds are emerging as a promising alternative to conventional packed beds in solvent-based carbon capture, owing to their high mass transfer rates and compact design. This paper discusses recent advances, challenges and future perspectives associated with RPB technology. Key issues include solvent stability and degradation, corrosion challenges, scaling up for industrial applications and other operational and maintenance hurdles. Future research should focus on developing novel solvents, optimising RPB design, creating high-fidelity models using hybrid approaches, and establishing robust and rigorous procedures for scaling up. Additionally, accurate techno-economic evaluations and exploring decentralised RPB deployment could enhance its commercialisation, making this technology viable for a broader range of industries.
