Abstract

This study was undertaken because of the concern over the influence of back-diffusion (defined as molecular diffusion counter to the flow of a fluid in a conduit) on the contamination of cryogenic liquids stored for long periods. There appeared to be a possibility that contamination of stored liquid oxygen, for example, might occur because of back-diffusion of carbon dioxide and water through the venting apparatus, Carbon dioxide and water vapor have partial pressures in the atmosphere much higher than the vapor pressures of their solid phases at liquid-oxygen temperatures.
