A global net zero target by mid-century and keeping the maximum global temperature rise to below 1.5 °C was agreed by nearly 200 nations at the 26th UN Climate Change Conference of the Parties. The Intergovernmental Panel on Climate Change advises that emission cuts by 45% are needed by 2030 in order to maintain the global temperature rise below the 1.5 °C target. To achieve this target, it is necessary to investigate technological options that are economically viable and globally acceptable for commercial deployment. This review paper looks at the new technologies needed to reduce CO 2 emission and to motivate commercial deployment, considering that the commercial deployment of CO 2 has been slowed down as a result of high capital and operating expenses which invariably increase the cost of energy. The paper presents a review on early years of process intensification technologies as well as a discussion on potential new process intensification options for CO 2 capture, with suggestions on how to modify those technologies for suitable application to solvent-based carbon capture. The work further discusses current process intensification technologies used for CO 2 capture applications. Solvent developments for enhancing CO 2 capture also are discussed as they contribute to cutting down the sizes of the units as well as decreasing the cost of regeneration which leads to reduction in capital and operating costs. A process flow diagram using a mop fan for capture of CO 2 from buildings is proposed. In addition, a new flow diagram is proposed for using loop reactor technology to capture CO 2 from large point sources, and finally a new process diagram using rotating packed bed absorber combined with sono-assisted regenerator is presented for improved performance of CO 2 capture technology. Recommendations on these diagrams are made to help ensure transition toward the net zero target.

“…Enhancing mass transfer between liquid absorbent and CO 2 is essential in intensifying CC using chemical adsorption. Different strategies have been reported to enhance gasliquid mass transfer, including the use of rotating spiral contactors [30], spinning disc reactors (SDRs) [31], microreactors [32] and rotating packed beds (RPB). In rotating spiral contacting, as the name suggests, the rotation of a spiral channel causes a centrifugal acceleration, forcing the gas and liquid to flow in parallel layers of uniform thickness.…”

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.
