In the separation of a more readily diffusing component from a gaseous mixture containing same and at least one less readily diffusing component, by diffusion via semipermeable membranes, a gas is fed to the passage side of the membranes, this gas being essentially free of ingredients of the more readily diffusing component, or in the alternative, such a gas also exhibiting a substantially higher rate of diffusion than the more readily diffusing component is fed to the barrier side. |
