“As shown in Fig. 3, heat of CO2 desorption for the degraded solution was slightly larger than that for fresh solution. This result can be explained qualitatively by examining the heat of absorption and the CO2 loading range for the solutions. Figure 9 shows the heat of absorption at 120 °C calculated by Aspen Plus®. The heat of absorption for the degraded solution is roughly equivalent to that for the fresh solution at a given CO2 loading. As already discussed in Section 3.2, the presence of HSS reduces the CO2 loading range, thereby altering the heat for CO2 desorption. The CO2 desorption heat is determined as the function of the CO2 loading range. In the degraded solution, the CO2 loading range is shifted down. (cf. Fig. 9).
