Abstract

Oxygen-ion conducting ceramic membrane materials (pure ionic or mixed ionic / electronic conductors) allow selective transport of oxygen in the form of ionic flux at high temperatures and can be used for the production of high purity oxygen. Such materials are also more appropriate for gas purification (residual oxygen removal) and control of oxygen levels in a gas stream to produce gases with known oxygen partial pressure. In this paper, operation and limitations of laboratory scale prototypes constructed from tubular zirconia — yttria membranes have been described for the removal of oxygen from air and low oxygen containing gases to produce oxygen-free gas streams and generation of calibration gases with pre-defined levels of oxygen.
