Model 7029-ISS-001 - Isotopic Separation System Brochure

This equipment is based on two molecular sieve packed columns, each cryogenically cooled with liquid nitrogen, and can alternatively be heated in small increments along their length. Mixed isotopes of hydrogen from an electrolyzer are batch injected into the system and deposited onto one of the two cooled columns. Temperatures are regulated to allow the isotopes to come off the first column in order of molecular size. By manipulating both columns simultaneously and transferring between the columns, it is possible to achieve a clean cut between the different isotopes and to deposit clean pure tritium onto a getter bed, and to discharge pure hydrogen to the stack thus reducing the volume before adding another batch.
