Production of pure oxygen from BSCF hollow fiber membranes using steam sweep

► Oxygen flux increased as a function of the steam sweep flow rate and temperature, reaching 9.52 ml min −1 cm −2 at 950 °C. ► Oxygen flux remained stable up to 20 h, though undergoing a significant reduction afterwards, while oxygen purity reduced after 40 h testing. ► Steam leached the elements of...
