Halogen Removal from Tritium Gas Streams
Halogen impurities are poisonous and/or corrosive • Poison for catalysts and equipment • Causes pitting in most austenitic stainless steels • Minimized to prevent damage over time • Prone to appear in certain processes • Appear if certain materials degrade (i.e., elastomers, etc.) • Present as trace impurities in a large number of metals and zeolites (<200 ppm)
