Abstract
A steady-state model for gas permeation by hollow membrane fibers is d eveloped for a multicomponent ideal gas system in countercurrent flow. Gas phase diffusion is shown to dominate transport in the substrate m aking local bore concentration, not diffusing species flux fraction, t he appropriate measure of permeate activity for this experimental syst em. The model is able to predict the experimental trends in a O-2/N-2/ polysulfone system.
