Numerical modelling of rotating packed beds used for <scp>CO₂</scp> capture processes: A review

Over the last decades, renewable and clean energy sources are being rigorously adopted along with carbon capture technologies to tackle increasing dioxide (CO2) concentration level in environment. CO2 is a quintessential option for tackling global warming issues. In this context, present paper has reviewed process intensification equipment called rotating packed bed (RPB), which highly industry applicable due high gravity (HiGee) force. This facilitates strong mass transfer characteristics, compact design, low consumption. review, current research scenario of RPBs using numerical, computational fluid dynamics (CFD), mathematical modelling, different machine learning approaches process, been reviewed. The geometry designs, hydrodynamic performance parameters, methods, their effects on removal efficiency have discussed. Furthermore, latest experimental studies also summarized, especially absorption adsorption domain. Finally, recommendations given support industrial commercial applications removal.
