“…This is because power plants require a large amount of ammonia water solution during denitrification, making equipment modification relatively easy and operations relatively simple. However, ammonia water is highly volatile, and once heated during the capture process, it will quickly evaporate, easily causing secondary pollution to the environment and making it difficult to store and recycle ammonia water [9, 10]. Afterward, Chen [11], Prakash [12], Silva [13], Kruszczak [14] and others conducted research on ethanolamine, diethanolamine, triethanolamine, and their mixtures, and obtained relevant experimental results.…”

The combination of zeolitic imidazolate framework‐8 (ZIF‐8) and ionic liquids (ILs) to create porous ionic liquids (PILs) is highly significant for efficient carbon dioxide (CO2) capture and the advancement of carbon capture, utilization, and storage (CCUS) technologies. To further investigate the CO2 capture characteristics of different PILs, two different‐sized ZIF‐8 structures and two functionalized ILs were prepared. Additionally, the enhancement factor of the reaction process was calculated using the dual‐film theory and mass transfer coefficient. The results demonstrated that the original [PMIm]Cl had low CO2 absorption capacity at ambient temperature and pressure, whereas the functionalized ILs had a maximum CO2 capture capacity of approximately .31 mol/mol, with the 20 wt% concentration of tetraethylene pentamine‐2‐methylimidazole ([TEP][MIm]) exhibiting the highest CO2 capture capacity of around 1.93 mol/mol. The synthesized PILs demonstrated a maximum CO2 capture capacity of approximately 2.22 and 2.16 mol/mol at 20 and 10 wt% ionic concentrations, respectively, with a porous ionic liquid addition of 1.0/100 g. The corresponding enhancement factors were 1.53 and 1.59, respectively. These findings have significant implications for CCUS technology.

“…Carbon dioxide (CO 2 ) plays an important role in daily production and life. It mainly derives from the respiration of animals, plants, and microorganisms, decomposition of carbonic acid minerals, and combustion of fossil fuels. − Especially large amounts of CO 2 have been emitted into the atmosphere since the industrial revolution. CO 2 and CH 4 are greenhouse gases with a significant impact on global climate change. − …”

Carbon dioxide (CO 2 ) bubbles are common during carbon capture, utilization, and storage (CCUS) processes and have many impacts on water conservancy machinery, metallurgy, and the chemical industry. To explore the dynamic characteristics of CO 2 bubbles in different liquids in CCUS, the motion mechanism of CO 2 bubbles was integrated, and the effects of different liquid characteristics and different external conditions on the dynamic characteristics of CO 2 bubbles were classified and summarized. At the same time, the research progress of numerical simulation on CO 2 bubble dynamics is reviewed. Therefore, approaches and methods that can be further explored in theoretical analysis, experimental research, and numerical simulation of CO 2 bubble dynamics are proposed, which can provide reference and guidance for engineering practice, especially CCUS technologies.

“…In recent years, with the development of computer technology, numerical simulation technology has gradually matured [15][16][17][18][19]. Compared with the experiments, numerical simulations of the insulator are mainly based on hydrodynamics, low-frequency electromagnetic field and particle two-phase flow to study the deposition process and adhesion mechanism of contaminated particles.…”

When separated water droplets condense on the surface of a composite insulator, the electrical field on the insulator surface is distorted. In turn, such distortions change the trajectories of pollution particles. In this study, the COMSOL software is used to simulate such a process for the FXBW4-10/100 composite insulator with or without water droplets condensation under a 10 kV DC voltage. The influence of the wind speed and particles concentration on the contamination characteristics of the considered 110 kV insulator is analyzed. The results show that: 1) in the presence of water droplets on the insulator surface, the ratio of electrical field force and gravity acting on the particles is large; 2) the contamination on the insulator surface increases with the wind speed; 3) when the wind speed is small, the relationship between the contamination amount and the pollution concentration is essentially linear.
