“…32 From the results, the average overall volumetric coefficients of mass transfer of MEA and the mixture based on it are higher compared to AMP. In addition, the MEA:AMP mixture gave a better performance in removing CO 2 compared to AMP alone, which is may be due a synergistic effect between the two solutions.…”

“…In the absorption experiment, the packed column [29][30][31], the wetted wall absorber [10,14,[32][33][34], the Rotating Packed Bed [4], the bubble column [11,[35][36][37][38], and other scrubbers [28,39] are often used. The operation of the packed column is complicated, and its operating costs are high, while the bubble column is characterized by its merits, as it has a controllable pH value, a high mass transfer coefficient, a high absorption factor, and it is easy to operate.…”

In order to select the best mixed amines in the CO2 capture process, the absorption of CO2 in mixed amines was explored at the required concentrations by using monoethanolamine (MEA) as a basic solvent, mixed with diisopropanolamine (DIPA), triethanolamine (TEA), 2-amino-2-methyl-1-propanol (AMP), and piperazine (PZ). Here, a bubble column was used as the scrubber, and a continuous operation was adopted. The Taguchi method was used for the experimental design. The conditional factors included the type of mixed amine (A), the ratio of the mixed amines (B), the liquid feed flow (C), the gas-flow rate (D), and the concentration of mixed amines (E). There were four levels, respectively, and a total of 16 experiments. The absorption efficiency (EF), absorption rate (RA), overall mass transfer coefficient (KGa), and scrubbing factor (<i>ϕ</i>) were used as indicators and were determined in a steady-state by the mass balance and two-film models. According to the Taguchi analysis, the importance of the parameters and the optimum conditions were obtained. In terms of the absorption efficiency (EF), the absorption rate (absorption factor) (RA/<i>ϕ</i>), and the overall mass transfer coefficient (KGa), the order of importance is D > E > A > B > C, D > E > C > B > A, and D > E > C > A > B, respectively, and the optimum conditions are A1B4C4D3E3, A1B3C4D4E2, A4B2C3D4E4, and A1B1C1D4E1. The optimum condition validation results showed that the optimal values of EF, RA, and KGa are 100%, 30.69 × 10−4 mol/s·L, 1.540 l/s, and 0.269, respectively. With regard to the selection of mixed amine, it was found that the mixed amine (MEA + AMP) performed the best in the CO2 capture process.
