To develop cost-effective CO 2 capture technology process intensification will play a vital role. In this work, the capabilities of a gas-liquid vortex reactor (GLVR) as novel process intensification equipment are evaluated by studying its interphase mass transfer parameters to build up the fundamentals for its future application to for example, CO 2 capture. The NaOH-CO 2 chemisorption system and Danckwerts' model are applied to obtain the effective interfacial area and liquid-side mass transfer coefficient. Results show that the gas-liquid contact in the GLVR is capable of both generating a large interfacial area in a small reactor volume and creating a region with high-energy dissipation to improve mass transfer. A comparison of the volumetric mass transfer coefficients with data reported in literature for conventional and intensified reactor types confirms a superior mass transfer efficiency and, most importantly, a favorable energetic efficiency of the GLVR.

The capture of CO2 in a rotating packed bed (RPB) using highly concentrated alkanolamine solutions has been proved to be an effective way to enhance the absorption efficiency of CO2. In this investigation, the effects of alkanolamine concentration on the CO2 removal efficiency and mass transfer coefficients (KGa) at various lean CO2 loadings were studied. Monoethanolamine and 2‐methyl‐amino‐ethanol solutions were used to absorb CO2 in an RPB. Experimental results showed that increasing the alkanolamine concentration effectively enhanced the CO2 absorption efficiency of a fresh absorbent. For an absorbent with a high CO2 loading, an optimal alkanolamine concentration was observed because the viscosity of the absorbent dramatically increased at high alkanolamine concentration and high CO2 loading. A correlation of KGa was proposed and the mass transfer coefficient can be expressed as a function of the free alkanolamine concentration and the viscosity of the absorbent.

Numerical modelling of rotating packed beds used for CO₂ capture processes: A review

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