Carbon utilization in natural gas combined cycle (NGCC) power plants has attracted great attention due to necessary carbon reduction demands. In this study, NGCC power plants integrated with the carbon capture and utilization process (CCU) were developed: Case 2 (NGCC power plant with CO 2 conversion on precarbon capture) and case 3 (NGCC power plant with CO 2 conversion on postcarbon capture). Integrated process configurations were evaluated and compared with case 1 (NGCC power plant only with postcombustion carbon capture) in terms of technical (net power generation, natural gas consumption rate, syngas production rate, CO 2 quantity released into the environment) and economic (total capital cost, total annual revenue, return on investment, payback period, and cash flow) performance. Here, case 2 represented the most environmentally friendly option with the lowest CO 2 released. Besides, case 3 generated the highest amount of electricity due to a lower compression pressure demand for CO 2 utilization than storage in case 1. The economic analysis indicated that the payback periods of cases 1, 2, and 3 were 9.2, 17.18, and 6.9, respectively. Case 3 was the best option under the least capital expenditure, operating expenditure, and the highest annual revenue. Additionally, case 2 was competitive in terms of low total capital cost as compared to case 1. Therefore, the suggested NGCC power plant processes with CCU are viable options for reducing CO 2 emissions and improving the economics of NGCC power plants. In addition, the process may be used as a model for further CO 2 utilization from flue gas released by gas power plants.

“…ILs are widely attractive due to their unique properties, including variable styles of anions and cations, good thermal and chemical stability, low melting point, low vapor pressure, good recycling, larger interface contact areas with vapors, and so on. According to their unique advantages, ILs are particularly suitable as promising adsorbents in various fields 27‐32 . To date, ILs, such as 1‐butyl‐3‐methylimidazolium aspartic acid [BMIM][ASP], 31 1‐butyl‐3‐methylimidazolium glycinate ([BMIM][Gly]), 33 and 1‐hexyl‐3‐methylimidazolium hexafluorophosphate [HMIM][PF 6 ], 34 have been explored in the research of CO 2 absorption.…”

BACKGROUND: Recent works have shown how to develop methods with specific economic and environmental aspects; this is the main motivation for research on energy efficient processes and environmentally friendly materials for formaldehyde (HCHO) storage. One specific goal is to improve the adsorption capacity for HCHO by constructing closely contacted connections with absorbents.RESULTS: In this study, two ionic liquids (ILs), 1-methylimidazole hydrogen sulfate [MIM][HSO 4 ] and Imidazole hydrogen sulfate [IM][HSO4] as newly developed absorbents for HCHO storage are applied for the first time. Based on thermogravimetric analysis (TGA) and nuclear magnetic resonance (NMR) results, it is concluded that their exceptional capacity for storage of HCHO is 31.07 and 34.60 (g formaldehyde)Á(mol ionic liquid) −1 , respectively. In addition, to study the renewability of HCHO, the decomposition rates of the reaction products (as a function of decomposition time and decomposition temperature) were measured. The optimal kinetic model was selected to satisfy the formation and decomposition processes of the products. Thereafter, the activation energy (E), pre-finger factor (A), decomposition rate constant of the decomposition reaction, and the rate constant of the reaction were determined. NMR results confirmed that the higher storage capacity of HCHO in [MIM][HSO 4 ] and [IM][HSO 4 ] is mostly attributed to the stronger covalent bonds between the ionic liquids (ILs) and HCHO.CONCLUSION: These ILs are, thus, promising candidates as adsorbents for the design of air depollution processes. This study may provide new insights into the use of ILs for storage of HCHO for low-cost, high-performance, and environmentally benign adsorbents for indoor air purification.

Ionic liquids have been studied as CO2 capture agents. However, they are rarely used in combined CO2 capture and conversion processes. Utilizing imidazolium‐based ionic liquids the conversion of CO2 to methanol was greatly improved in polyamine assisted systems catalyzed by homogeneous pincer catalysts with Ru and Mn metal centers. Among the ionic liquids tested, [BMIM]OAc was found to perform the best under the given reaction conditions. Among the polyamine tested, pentaethylenehexamine (PEHA) led to the highest conversion rates. Ru‐Macho and Ru‐Macho‐BH were the most active catalysts. Direct air capture utilizing PEHA as the capture material was also demonstrated and produced an 86% conversion of the captured CO2 to methanol in the presence of [BMIM]OAc.
