Novel dense perovskite BaBi0.05Sc0.1Co0.85O3-δ (BBSC) membranes showed promising flux performance to separate oxygen from air. The oxygen transport through BBSC in discs and hollow fibres geometry were modelled as a function of oxygen partial pressure in the permeate side and temperature using simple correlations. The oxygen diffusion (DO) and surface exchange (kS) coefficients and also the characteristic thickness (LC) were extracted from the series of flux data based on disc membranes. Employing the obtained oxygen diffusion coefficient, the surface exchange coefficients (kf and kr) for the hollow fibre geometry can then be obtained from another tubular correlation by fitting with flux data based on hollow fibre membranes. The physical importance of the parameters (i.e. DO, kS, LC, kf and kr) was discussed. The effects of controllable variables, i.e. temperature and oxygen partial pressure, in the permeate side onto oxygen flux performance were also elaborated.
