Membrane technology is extensively used for industrial gas separation. A steady-state model for gas permeation by hollow membrane fibers is developed for a multicomponent ideal gas system in countercurrent flow. Gas phase diffusion is shown to dominate transport in the substrate making local bore concentration, not diffusing species flux fraction, the appropriate measure of permeate activity for this experimental system. The model is able to predict the experimental trends in a O{sub 2}/N{sub 2}/polysulfone system.
