“…In total, 20 wt% monoethanolamine (MEA) is used as the absorbent due to its advantages of high absorption capacity, low volatility and regeneration energy, easy availability and cost effectiveness [23]. Specific to the membrane material, the polypropylene (PP) membrane is selected in this study due to its high void volume, wide commercial size, cost effectiveness, high chemical stability, and thermal stability [24]. The flue gas emitted from the power plant first passes through a heat exchanger chilled by air to reduce the gas temperature, and is further pretreated with desulfurization and dust removal processes before entering the hollow fiber membrane contactor.…”

In this study, a novel system which integrates solar thermal energy with membrane gas absorption technology is proposed to capture CO2 from a 580 MWe pulverized coal power plant. Technical feasibility and economic evaluation are carried out on the proposed system in three cities with different solar resources in China. Research results show that the output capacity and net efficiency of the SOL-HFMC power plant are significantly higher than those of the reference power plant regardless of whether a TES system is applied or not. In addition, the CEI of the SOL-HFMC power plant with the TES system is 4.36 kg CO2/MWh, 4.45 kg CO2/MWh and 4.66 kg CO2/MWh lower than that of the reference power plant. The prices of the membrane, vacuum tube collector and phase change material should be reduced to achieve lower LCOE and COR values. Specifically for the SOL-HFMC power plant with the TES system, the corresponding vacuum tube collector price shall be lower than 25.70 $/m2 for Jinan, 95.20 $/m2 for Xining, and 128.70 $/m2 for Lhasa, respectively. To be more competitive than a solar-assisted ammonia-based post-combustion CO2 capture power plant, the membrane price in Jinan, Xining and Lhasa shall be reduced to 0.012 $/m, 0.015 $/m and 0.016 $/m for the sake of LCOE, and 0.03 $/m, 0.033 $/m and 0.034 $/m for the sake of COR, respectively.

“…Energies 2024, 17,2371 and heat consumption are the primary contributors to environmental impacts, whi absorbent and uncaptured CO2 have influences on limited indicators. Therefore, fr perspective of environmental impact, more efforts should be made to optimize the efficiency of membrane gas absorption systems.…”

“…Attributed to its flexible operation, compact specification, high surface-area-to-volume ratio, linear scale-up feasibility, modular design and other benefits [14][15][16], membrane gas absorption technology has already been identified as one of the most promising alternatives to conventional technologies for CO 2 mitigation. In the past two decades, most of the research conducted has mainly focused on the technical and economic feasibility of membrane gas absorption for CO 2 capture from the perspectives of membrane materials, absorbent types and operating parameters through experimental and numerical simulations [17][18][19][20]. However, the environmental impact of the membrane gas absorption for CO 2 capture, which can be used to evaluate the real sustainability of the CO 2 capture processes regarding all environmental aspects, has seldom been studied in the previous literature.…”

Membrane gas absorption technology has been considered a promising approach to mitigate CO2 emissions from power plants. The aim of this study is to evaluate the environmental impacts of CO2 absorption and desorption processes by hollow fiber membrane contactors using a life cycle assessment methodology. On the basis of the ReCipe 2016 Midpoint and the ReCipe 2016 Endpoint methods, the research results show that membrane gas absorption systems exhibit the lowest environmental impacts across the majority of assessed categories in comparison with chemical absorption and membrane gas separation systems. The CO2 capture process via membrane gas absorption has the most significant impact on the METP category, with heat consumption as the primary contributing factor accounting for 55%, followed by electricity consumption accounting for 43.1%. According to the sensitivity analysis, heating by natural gas shows better performance than other heat supply sources in improving overall environmental impacts. In addition, the increasing utilization of renewable energy in electricity supply reduces the global warming potential, fossil resource consumption and ozone formation.
