| Methane | 97.5 | 1.56 b | 2.7 c | — |
| Ethylene | 152.5 | 2.8 b | — | 4.5 d |
| Ethane | 67.5 | 1.38 b | — | 1.63 d |
aFeed pressures corresponding to the average ICR concentrations obtained from simulations are 3.9 bar for methane, 4.8 bar for ethylene and 4.8 bar for ethane.
bFeed pressure = 1 bar, Pan et al.;40.
cFeed pressure = 1 bar, Bux et al.;42.
dFeed pressure = 6 bar, Bux et al. 41 (see Table S3 for the computed fluxes used for the calculation of permeabilities).
