When considering the absorber sump, the sensitivity of the stored rich solvent is highly dependent on the assumptions made regarding the degree of O2 mass transfer into the rich solvent. Where no mass transfer of O2 occurs, analogous to an independent storage system with minimal contact with atmospheric air or gas capping, no increase in oxidative degradation occurs as the degradation reaction quickly reaches equilibrium as the dissolved O2 in the solvent is consumed. However, if the stored solvent remains saturated with O2, the increase in degradation is linear with residence time. As previously mentioned, the likely effect is somewhere between these two extremes; however, the reduction of absorber sump residence times with independent rich solvent storage systems may provide a benefit if longer-term storage is required.
