The above paper reports the results and discussion about the influence of MEA concentrations on mass transfer coefficient at liquid flow rate of 7.6 × 10−4 m3/min (Figure 6 of the reference) and 11.4 × 10−4 m3/min (Figure 7 of the reference). In general, the increase of MEA concentration increased viscosity of the solvent and lowered the CO2 solubility in the solution. The influence of liquid flow rate (Figure 8 of the reference) on mass transfer was also reported.
