The difference between no degradation and fast degradation is less significant for sorbents with working capacities above 2.0 mmol/g, but continuing to use these sorbents past the optimum replacement time will increase the cost. Additionally, it is clear that using a sorbent with a high capacity and high degradation rate can be less economically viable than a sorbent with a low capacity and low degradation rate. Similarly, sorbents with fast kinetics (i.e., short cycle times) and high degradation rates can be higher in cost than sorbents with longer cycle times and low degradation rates. A single sorbent property cannot be used as a predictor for economic viability of DAC.
