“…Other concerns that need to be addressed for effective application of DP packing in CO 2 capture include packing stability and its influence on solvent degradation, and whether the packing materials can endure high stripping temperatures and show both chemical and mechanical stability over a long period. This latter is because the packing can potentially enhance CO 2 stripping from solvent as a result of its better contact with steam and the turbulence effect 123 …”

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.

Development of enhanced three‐dimensional printed packings for scale‐up of distillation columns: A successful case study

et al. 2022

This publication presents a general approach for the enhancement of packings regarding scalability, separation efficiency, and fluid dynamic properties using threedimensional (3D) printing. The methodology is used to develop miniaturized, scalable packings for process development, and scale-up applications. For this purpose, a 3D printable computer-aided design version of the Rombopak 9M industrial packing (RP9M-3D), which is known for its positive scalability properties, was created. An initial characterization by means of computational fluid dynamics simulations and mass transfer measurements reveals positive but also negative design properties. These findings are used to create a more advanced, miniaturized packing structure, the XW-Pak. The evolved structure is compared to the RP9M-3D. The simulation and experimental results show that the enhanced packing, which is still in the early stages of development, exhibits higher separation efficiencies with improved scalability properties at the same void fraction and surface area than the RP9M-3D.

Carbonic anhydrase (CA) is an attractive biodegradable catalyst for CO2 absorption in solvent‐based CO2 capture. However, maintaining the stability of CA as a homogeneous component of the solvents is a challenge. Solvent regeneration temperature typically exceeds the enzyme thermal tolerance, which leads to CA deactivation. To reduce the need for frequent CA replenishment and to avoid inactive CA accumulation in the solvent, this work shows the benefits of an immobilization strategy where CA is fixed in a second‐generation design of textile structured packing (CATSP‐2) modules. The enzyme‐immobilized packing showed 1.5 times better performance in CO2 separation compared with traditional structured packing with a corresponding increased CO2 loading in the rich solvent. The modules exhibited good CA activity retention of ~80% during the tests without any CA replenishment. Applying CATSP‐2 could potentially decrease the packing height and absorber column size for a lower cost per amount of CO2 captured.
