摘要：

Detailed concentration and temperature measurements are reported for the absorption of CO2 from air into aqueous NaOH, monoethanolamine (MEA) and 2-amino-2-methyl-1-propanol (AMP) solutions. An absorber (0.1 m i.d. packed with 12.7 mm Berl Saddles up to heights of 6.55 m) was used which operated in countercurrent mode and near ambient conditions. The measurements for the CO2-NaOH and CO2-MEA systems are compared with predictions from a mathematical model and gave generally good agreement, except at high CO2 loadings of MEA solutions. Compared with MEA, AMP was found to have superior CO2 absorption capacities and inferior mass transfer rates.
