The outputs of the process modelling are described in section 3.1 are detailed in Table . As previously described by Mullen et al. and Su et al. , when lean loading is reduced accordingly as CO2 capture fraction increases and regeneration conditions are optimised, minimal differences in the specific energy requirements are observed, and in some cases, a reduction is seen. This is most pronounced in the CCGT case as the driving force of absorption at the top of the absorber is still moderately low, even for a 95% CO2 capture rate at a lean loading of 0.2 mol/mol. A reduced SRD is predicted in all 95% CO2 capture cases if lean loading is reduced below 0.2 mol/mol, as per Mullen et al. and Su et al. However, this research aims not to optimise thermal efficiency but to compare solvent degradation rates at typical operational conditions with those considered beneficial when achieving 100% added CO2 capture. Nonetheless, an additional case was included where a 95% CO2 capture rate was achieved for a CCGT flue gas at 0.1 mol/mol lean loading and 24m of absorber packing. A 15.3% reduction in SRD was observed, representing a substantial energy saving at the expense of a 23.7% increase in solvent degradation rates, which is discussed in section 3.2, and an undetermined effect on plant CAPEX and CO2 compressor power. This demonstrates that the energy benefits of low lean loading operation aren't specific to high CO2 capture fractions and must be a project-by-project cost optimisation decision. Indeed, if solvent degradation is more critical to a project than thermal efficiency, lean loadings sufficient to achieve high CO2 capture fractions can be achieved at lower pressure/temperature regeneration conditions.
