| Abstract | Article history: Received 11 January 2017 Received in revised form 17 February 2017 Accepted 17 February 2017 Available online 8 April 2017 Amathematic model is developed for the perovskite-typemixed ionic-electronic conducting (MIEC)membrane, which makes it possible to simulate the process of oxygen separation in the U-shaped Ba0.5Sr0.5Co0.8Fe0.2O3 − δ hollow-fiber membrane. The model correlates the oxygen permeation flux to the measurable variables. The trends of calculated results for purge operation coincide well with the experimental data, therefore the model is considerable for flux prediction under vacuum operation. Higher oxygen separation efficiency can be achieved with vacuum operation than purge operation. Parameter study with vacuum operation reveals that oxygen permeation flux increases with higher vacuum levels, and vacuum pressure of around 1.013 × 10 Pa is the optimal. Also, vacuum operation on the lumen side ismuchmore efficient to achieve higher oxygen permeation flux compared with compression mode on the shell side. © 2017 The Chemical Industry and Engineering Society of China, and Chemical Industry Press.
