Dual-mode sorption behavior, effect

These two effects are summarized in Table 20.4-8. Moreover, the percentage reduction in flux for each component dne to nonideal gas-phase effects is listed in Table 20.4-8. Ii is clear ther the redaction in fugacity driving force is very smell (0.5%) for methane, which tends to he an ideal gas under these conditions. For CO2, however, rhe effects amonnt 10 roughtly 7,5% and account for a roughly 6,9% reduction in the ides] separation factor. To reemphasize, these effects would be observed even if the polymer-phase sorption and transport behavior did not show dual-mode effects and were perfectly ideal.
