“…While the CO2 loadings were much lower, the trend showed that duty decreased as the loading increased despite the lower CO2 loadings. Knudsen et al [48] showed the lowest specific reboiler duty at high CO2 loading and closely matched the current simulation results at 87% CO2 absorption. Table 6 presents the simulation kinetic data and a literature validation comparison.…”

Environmental preservation presents numerous challenges, particularly in capturing carbon di-oxide. Despite multiple studies on this topic, there remains a need for additional capture plants, particularly in the energy sector. The power industry emits flue gas during its post-combustion process, and capturing carbon dioxide from this gas would make power plants more environ-mentally friendly while aiding the preservation of the planet. The work conducted in This study aimed to investigate the gap in knowledge to contribute to the development of a better world without harming it. The identified research gap reveals no established optimal monoethanola-mine (MEA) solvent concentration for the process. A simulation was performed using Aspen Hysys to analyze the absorption efficiency at higher solvent concentrations and address this is-sue. The input data was obtained from a flue gas capture plant in the UK. The results obtained from discrete increments indicate an optimal solid result for an MEA concentration of 36 wt.%. Further analysis of temperature and pressure revealed that other solvents, such as diethanola-mine (DEA) and triethanolamine (TEA), are more stable at higher concentrations and that DEA and TEA at the same concentration as MEA consumed significantly less energy to capture carbon dioxide.

“…It can also be used in other industries: iron and steel, cement, synthetic fuel and ammonia production, biomass combustion, oil refineries, natural gas processing plants, etc. Post-combustion CO2 capture has been practiced for over 80 years; another option is to capture CO2 during combustion (before combustion); a third option is to replace combustion air with pure O2 mixed with recirculated flue gases [4][5][6]. This concept is commonly referred to as oxyfuel combustion; it produces a flue gas consisting only of CO2 and H2O.…”

The experience of technologically developed countries in solving the problems of improving the operational efficiency and environmental sustainability of coal-fired power generation of the Republic of Kazakhstan by involving H2C-technology and RE-components is summarized. It is shown that the successful example of technologically developed countries allows to use them as a transfer for energy systems of industrial heat generation in Kazakhstan.
