Table 1. Diffusion coefficients of water, equilibrium times of water and CO2 in four samples.
D(m2/s × E-12) | Tw (s) | Tc(s) | ΔT (s) | |
---|---|---|---|---|
(A)P-100-90C | 6.503 | 1020 | 1086 | 66 |
(B)P-100-50C | 2.536 | 1740 | 2462 | 722 |
(C)P-100-25C | 1.842 | 7200 | 10628 | 3428 |
(D)I-200 | 58.464 | 6300 | 8970 | 2670 |
D is the diffusion rate of H2O; Tw is the equilibrium time of absorbed H2O by absorbent; Tc the equilibrium time of desorbed CO2 by absorbent. ΔT = Tc−Tw
