Xenon separation technologies

Krypton/ Xenon separation technologies from reprocessing/recycling plant. 

By far the most fully developed application for carbon molecular sieves is in the separation of small gas molecules. A large number of patents describe claims for materials and processes that include carbon-based sieves. Separations that have been accomplished include oxygen and nitrogen, hydrogen and coke gases, methane and carbon dioxide, methane and xenon, ethylene and ethane, propylene and propane. A number of companies in Europe and the United States have recently offered commercial systems for the separation of nitrogen from air. A review of the use of carbon molecular sieves in separation technology is well beyond the scope of this article and the interested reader is referred to recent reviews and references sited therein (12,18.). ... 

Different combinations of stable xenon isotopes have been sealed into each of the fuel elements in fission reactors as tags so that should one of the elements later develop a leak, it could be identified by analyzing the xenon isotope pattern in the reactor s cover gas (4). Historically, the sensitive helium mass spectrometer devices for leak detection were developed as a cmcial part of building the gas-diffusion plant for uranium isotope separation at Oak Ridge, Tennessee (129), and heHum leak detection equipment is stiU an essential tool ia auclear technology (see Diffusion separation methods).
