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.

“…In effect, NTP decomposes CO 2 into carbon monoxide (CO) and oxygen (O 2 ) with the use of Ar as a diluent gas. 17 Alternatively, other studies have shown the possibility to perform the process in a nitrogen (N 2 ) environment, resulting in an overall lower cost. 18 Subsequently, the CO produced is usually coupled with a hydrogen source (H 2 ) to produce syngas (CH 4 ).…”

Carbon dioxide (CO2) transformation into added-value products through non-thermal plasma (NTP) represents a novel technology of interest. The process involves, apart from CO2, mixtures of different gases such as carbon monoxide (CO), oxygen (O2), nitrogen (N2), argon (Ar), and hydrogen (H2) for subsequent CO2 methanation. In this work, a preliminary study of the thermodynamic representation of the mixtures relevant in the context of carbon capture, utilization, and storage (CCUS) processes, but focused on the NTP conversion, is presented. The thermodynamic characterization is achieved through the application of the polar soft-statistical associating fluid theory (SAFT) equation of state (EoS), which allows molecular parameterization of pure compounds and the description of mixtures at different conditions of temperature and pressure. An accurate parametrization of all gases is carried out by explicitly considering the quadrupolar nature of CO2, CO, and N2. The characterization is then used to describe several single-phase densities, derivative properties, second virial coefficients, and the vapor–liquid equilibrium (VLE) of CO2 binary mixtures with Ar, O2, CO, N2, and H2, as well as combinations between some of these gases. A parametric analysis of the impact of the binary parameters on the equilibria description is carried out to assess the temperature dependency. The results have overall shown good agreement to experimental data in most conditions using one or two binary parameters. Finally, ternary systems involving CO2, O2, Ar, and N2 have been predicted in good agreement with the experimental data, demonstrating the capacity of the model to evaluate the behavior of multicomponent gas mixtures.

“…DBD plasma is advantageous for CO2 decomposition in terms of expandability and ease of operation. The CO2 conversion by the DBD plasma is up to 40%, but it is difficult to be used as a suitable technology for CO2 splitting due to its low energy efficiency of less than 10% [3]. MW plasma provides the high energy efficiency higher than 60% due to the combination of relatively high electron density and low field decay.…”
