“With the development of CCS technologies, amine-based post-combustion technologies could approach a commercial-scale project first, which remains the preferred CO2 capture technology for the short and medium term [6,7]. However, high energy consumption obstructs the popularization and application of CCS [8]. In recent years, many researchers have given much attention to the development of new amine-based solvents. Table 1 summarizes the energy performance of three kinds of new amine-based solvents.”
