“…The authors emphasised that the parameters for the electrostatic potential surface area are important and effective descriptors for predicting the toxicity of ILs. Borhani et al 76 used GA-MLR method to develop a model to predict the partial pressure of CO 2 , the heat of absorption, and K-values for CO 2 absorption in 30, 45, and 60 wt. % MEA aqueous solutions.…”

“…The energy requirement for solvent regeneration is a critical issue in using the absorption-desorption system which required around 20-30% of the power produced by a power plant [13]. The majority of energy consumption is related to the regeneration unit [22,23]. Therefore, the design and operation of the regeneration unit have high importance in the chemical absorption process.…”

Solvent selection and design are imperative in the CO2 capture process. The efficiency and the overall cost of the process are directly affected by the solvent as a consequence of the effect of solvent on factors such as CO2 absorption capacity, size of equipment, and solvent regeneration energy. This review paper aims to review the most important solvents and mixtures of solvents, absorbing CO2 via chemisorption, physisorption and chemi-physisoprtion. Characteristic and structure of different solvents are presented with the advantages and disadvantages of each being highlighted. Mixtures of solvents include chemical or physical solvents only, and combinations of physical and chemical solvents are categorised. In addition to common solvents, phase change solvents are also described. Once a comprehensive list of solvents is presented, different methods of solvent selection and design are illustrated, namely methods involving experiments, process and equilibrium models, predictive models, and computer-aided molecular design (CAMD). The importance of integrated solvent and process selection and design is also discussed. The most recent and selected progress studies in each section are reviewed in detail.

“…integrating the reboiler within the RPB desorber unit. The overall cost of CO 2 capture in a power plant deploying an RPB-based process has been evaluated to be marginally lower at 61€/ton CO 2 vs. 65€/ton CO 2 for a conventional packed column process [57]. Clearly, there is scope for further decreases in operating costs in such PI based processes via greater integration of energy across the absorption and desorption cycles and reduced energy consumption in the reboiler for the desorption process [56].…”

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.
