“…Additionally, the selection of these specific molarity ratios was based on a comprehensive literature review and preliminary experiments. [ 41 ] The range of ratios that have been commonly studied in the field was taken into consideration and incorporated to cover a broad spectrum of concentrations, ensuring a comprehensive analysis of the system's behavior. As a result, the nine MEA–R 3 N–PZ blends were suggested: 3:1.75:0.25, 3:1.5:0.5, 3:1:1 (for 5 m ) and the nine AMP–R 3 N–PZ blends were suggested: 3:1.75:0.25, 3:1.5:0.5, 3:1:1 (for 5 m ).…”

The CO2 absorption–desorption performances of nonaqueous trisolvent blended amines, monoethanolamine (MEA), 2‐amino‐2‐methyl‐1‐propanol (AMP), methyl diethanol amine (MDEA), 1‐dimethyl amino‐2‐propanol (1DMA2P), diethyl ethanol amine (DEEA), and piperazine (PZ), are investigated in terms of desorption parameters. Two trisolvent amine combinations, primary amine (MEA)/sterically hindered amine (AMP) and tertiary amine (MDEA/1DMA2P/DEEA)‐polyamine (PZ), are prepared at 5 m total amine concentrations with different molarities. Response surface methodology based on a central composite design is used to obtain the optimal condition. This study aims to determine the molarity ratios of solvent systems and investigate their effects on objective functions: heat duty, desorption rate, and desorption factor. Surface analysis suggests optimum conditions as 3 m MEA–1.375 m MDEA–0.625 m PZ for the lowest energy consumption. The experimental results of the proposed system are compared with the 5 m MEA solution. The extensive energy penalty of the CO2 desorption of amine absorbents is reduced with the newly developed solution.

“…Mondal et al measured the vapor-liquid equilibrium data of CO 2 absorption using a mixture of polyamine bis (3-aminopropyl) amine (DPTA) and MEA in an aqueous solution, and found that its CO 2 loading capacity was 0.7 mol CO 2 /mol antioxidants [31]. Apaiyaku et al explored the potential of high-concentration AMP-PZ-MEA solvents to capture CO 2 from solvent precipitation, density, viscosity, and CO 2 absorption capacity, and found that, compared to an MEA solvent, they had an increase of 25% in their CO 2 loading [32].…”

As the global climate crisis escalates, reductions in CO2 emissions and the efficient utilization of carbon waste resources have become a crucial consensus. Among the various carbon mitigation technologies, the concept of power-to-liquid (PTL) has gained significant attention in recent years. Considering the lack of a timely review of the state-of-the-art progress of this PTL process, this work aims to provide a systematic summary of the advanced PTL progress. In a CO2 capture unit, we compared the process performances of chemical absorption, physical absorption, pressure swing adsorption, and membrane separation technologies. In a water electrolysis unit, the research progress of alkaline water electrolysis, proton exchange membrane water electrolysis, and solid oxide water electrolysis technologies was summarized, and the strategies for improving the electrolysis efficiency were proposed. In a CO2 hydrogenation unit, we compared the differences of high-temperature and low-temperature Fischer–Tropsch synthesis processes, and summarized the advanced technologies for promoting the conversion of CO2 into high value-added hydrocarbons and achieving the efficient utilization of C1–C4 hydrocarbons. In addition, we critically reviewed the technical and economic performances of the PTL process. By shedding light on the current state of research and identifying its crucial factors, this work is conducive to enhancing the understanding of the PTL process and providing reliable suggestions for its future industrial application. By offering valuable insights into the PTL process, this work also contributes to paving the way for the development of more efficient and sustainable solutions to address the pressing challenges of CO2 emissions and climate change.
