“…Likewise, Ma, Wang et al [83] used [bmim][PF 6 ] and [bmim][BF 4 ] for their analysis to separate CO 2 from flue gas and got the purity as 90% for the CO 2 rich stream after separation. [hmim][Tf2N] gave 93.7% pure CO 2 in an alternative study [84]. Khonkaen, Siemanond et al [58] Even though there has been a fast rise in attention in ILs over the past 20 years and a lot of research studies are being performed, only a small number of procedures have been commercialized for the treatment of industrial gas effluent as of yet.…”

The recent advancement in efficient and recoverable CO2 capture solvents has been stimulated by the environmental harm resulting from the accumulation of greenhouse gases. Ionic liquids (ILs) and IL-based solvents have given rise to a novel method of CO2 collection that is highly efficient, economical, and environmentally benign. However, there is a lack of knowledge about the implementation of this process on a wider scale, and it has limitations, including high solvent costs. This simulated study shows that [EMIM][NTF2] can remove up to 99.4% of the CO2 from industrial waste effluents using three distinct compositions. Following an economic study using a 20-year plant life estimate, with a plant capacity of 4000 kg/h (206.165 kmol/h) for the raw mixed stream flow (inlet) and a maximum CO2 capacity of 38.1 kmol/h, it was determined that the process’s overall annualized cost was USD 2.1 million with operating expenses being USD 1.8 million. The Aspen Activated Energy Analysis’s recommendation of adding a heat exchanger, with a payback year of 0.0586 years, a 23.34 m2 area, and potential energy cost savings of USD 340,182/Year was also implemented successfully. These findings propose a conceptual framework for the development of novel ionic liquids for CO2 capture. It also demonstrates that sustainable [EMIM][Tf2N]-based absorption techniques for CO2 capture have the potential to be an industrial technology.

“…Alternatively, multistage flash separation systems with two, three, or more units operating at different pressures and/or temperatures have been proposed for the IL regeneration stage to ensure the desired CO 2 stream purity (for example, suitable for transport and storage) and the recovery of the other relevant absorbed gas components (CH 4 , H 2 , etc.) from the IL-rich stream. ,,,,− ,,,− Thus, in the previously cited study by Basha et al, the IL-rich stream (at 30 bar) was regenerated using the pressure-swing option with three adiabatic flashes operating at 20, 10, and 1 bar. This flash train enabled the efficient regeneration of the exhausted IL and the separation of the absorbed gases from the IL and generated a CO 2 -rich gas stream.…”

“…Interestingly, the optimized IL chemical structure was different for each point on the Pareto curve, demonstrating that the IL and process design were strongly related. Leonzio et al used the ([hmim][NTf 2 ]) IL to optimize the carbon-capture process from flue gas, Aspen Plus software for rate-based process simulations with the APEA PR thermodynamic model for estimating process costs, and Minitab for the response-surface methodology to minimize the costs and maximize the amount of CO 2 captured through the response-surface methodology . The inlet temperature of the flue gas, absorption column pressure, CO 2 composition of the flue gas, and height of the absorption column were the considered factors, while the CO 2 recovery percentage, operating costs, and capital costs were the analyzed responses.…”

Ionic liquids (ILs) are promising alternative compounds that enable the development of technologies based on their unique properties as solvents or catalysts. These technologies require integrated product and process designs to select ILs with optimal process performances at an industrial scale to promote cost-effective and sustainable technologies. The digital era and multiscale research methodologies have changed the paradigm from experiment-oriented to hybrid experimental−computational developments guided by process engineering. This Review summarizes the relevant contributions (>300 research papers) of process simulations to advance IL-based technology developments by guiding experimental research efforts and enhancing industrial transferability. Robust simulation methodologies, mostly based on predictive COSMO-SAC/RS and UNIFAC models in Aspen Plus software, were applied to analyze key IL applications: physical and chemical CO 2 capture, CO 2 conversion, gas separation, liquid−liquid extraction, extractive distillation, refrigeration cycles, and biorefinery. The contributions concern the IL selection criteria, operational unit design, equipment sizing, technoeconomic and environmental analyses, and process optimization to promote the competitiveness of the proposed IL-based technologies. Process simulation revealed that multiscale research strategies enable advancement in the technological development of IL applications by focusing research efforts to overcome the limitations and exploit the excellent properties of ILs.

“…Room-temperature ionic liquids, which are relatively new compounds, have gained much attention in recent years, and had the potential to be considered as an alternative to conventional volatile organic solvents in the reaction and separation processes. Information about the solubility and the rate of solubility is a crucial factor for consideration of ionic liquids in potential industrial processes [2,3]. A large number of ionic liquids can be synthesized due to their special ionic structure.…”

Prediction of the Solubility of CO2 in Imidazolium Ionic Liquids Based on Selective Ensemble Modeling Method

Solubility data is one of the essential basic data for CO2 capture by ionic liquids. A selective ensemble modeling method, proposed to overcome the shortcomings of current methods, was developed and applied to the prediction of the solubility of CO2 in imidazolium ionic liquids. Firstly, multiple different sub–models were established based on the diversities of data, structural, and parameter design philosophy. Secondly, the fuzzy C–means algorithm was used to cluster the sub–models, and the collinearity detection method was adopted to eliminate the sub–models with high collinearity. Finally, the information entropy method integrated the sub–models into the selective ensemble model. The validation of the CO2 solubility predictions against experimental data showed that the proposed ensemble model had better performance than its previous alternative, because more effective information was extracted from different angles, and the diversity and accuracy among the sub–models were fully integrated. This work not only provided an effective modeling method for the prediction of the solubility of CO2 in ionic liquids, but also provided an effective method for the discrimination of ionic liquids for CO2 capture.
