“Figure 3 represents the solubility of CO2 in each amine solution at the partial pressure of CO2 from 5
to 100 kPa and temperature from 30 ° C to 80 ° C. The results can be observed that the solubility of
CO2 at higher temperatures have less capacity when compared with the solubility of CO2 at lower
temperatures. The absorption process is considered as absorption of CO2 at low temperature when the
temperature increases, it results in the lower CO2 loading capacity. At high temperature, it is
considered as a regeneration condition since the gas is removed from the solvent. In this study, the
temperature at 40 ° C and 80 ° C are considered as the absorption and regeneration conditions, respectively. Thus, it leads to an explanation of the cyclic capacity. In addition, the partial pressure of
CO2 increases from 5 to 100 kPa will become the mass driving force of CO2 in the gas phase transfer
to the liquid phase. Therefore, the higher of partial pressure of CO2 can capture the higher amount of
CO2. ”
