“…With its intense fluid dynamics and mass transfer, low absorbent concentrations can be used in RPBs to achieve similar performance to that of a large conventional absorber column. Chamchan et al [53] observed that both the RPB and conventional packed bed absorbers demonstrated similar absorption performance and energy consumption in CO 2 capture at pilot scale but the RPB was associated with a 1/3 volume reduction compared to the conventional packed bed. In CC from flue gas with low CO 2 concentration, Xie et al [52] demonstrated the RPB to be capable of achieving a mass transfer coefficient around 2.7x higher than in a packed column, with a corresponding 2.6x reduction in equipment volume.…”

Process intensification technologies for CO2 capture and conversion – a review

With the concentration of CO 2 in the atmosphere increasing beyond sustainable limits, much research is currently focused on developing solutions to mitigate this problem. Possible strategies involve sequestering the emitted CO 2 for long-term storage deep underground, and conversion of CO 2 into value-added products. Conventional processes for each of these solutions often have high-capital costs associated and kinetic limitations in different process steps. Additionally, CO 2 is thermodynamically a very stable molecule and difficult to activate. Despite such challenges, a number of methods for CO 2 capture and conversion have been investigated including absorption, photocatalysis, electrochemical and thermochemical methods. Conventional technologies employed in these processes often suffer from low selectivity and conversion, and lack energy efficiency. Therefore, suitable process intensification techniques based on equipment, material and process development strategies can play a key role at enabling the deployment of these processes. In this review paper, the cutting-edge intensification technologies being applied in CO 2 capture and conversion are reported and discussed, with the main focus on the chemical conversion methods.

“…Many investigations have studied the capture of CO 2 in an RPB using various alkanolamine solutions, including monoethanolamine (MEA), 2‐amino‐2‐methyl‐1‐propanol (AMP), methyl‐diethanolamine (MDEA), 2‐(2‐aminoethylamino)ethanol (AEEA), diethanolamine (DEA), diethylenetriamine (DETA), 2‐methyl‐amino‐ethanol (MMEA) and piperazine (PZ) . Alkanolamines that react rapidly with CO 2 , such as MEA, MMEA, AEEA, DETA, and PZ are favored because of the short residence time in an RPB.…”

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.

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.
