“Figure 2 shows the solubility of CO2 in 30 %wt of 2-MAE, 15:15 %wt of MEA:2-MAE and 30 %wt
of MEA at the temperature of 40 ° C and 80 ° C and partial pressure of CO2 at 15 kPa. The results of
CO2 loading at 40 ° C shows that 30 %wt of MEA provides higher absorption capacity than that of
15:15 %wt of MEA:2-MAE and 30 %wt of 2-MAE for 4.51 % and 7.04 %, respectively. At 80 ° C, it
shows that 30 %wt of MEA provides much higher absorption capacity than that of 15:15 %wt of
MEA:2-MAE and 30 %wt of 2-MAE for 11.15 % and 19.38 %, respectively. This means that 30 %wt
of 2-MAE can absorb less at regeneration condition. At partial pressure lower than 15 kPa, 30 %wt of
2-MAE provides less absorption capacity than the mixed amine solution and 30 %wt of MEA
especially at the higher temperatures. ”
